Abstract ：
Copper particles emitted from braking have become a significant source of environmental pollution. However, copper plays a crucial role in resin-based braking materials. Developing high-performance braking materials without copper has become a significant challenge. In this paper, the resin-based braking materials were filled with fly-ash cenospheres to develop copper-free braking materials. The effects of fly-ash cenospheres on the physical properties, mechanical and friction and wear properties of braking materials were studied. Furthermore, the wear mechanism of copper-free resin-based braking materials filled with fly-ash cenospheres was discussed. The results indicate that the inclusion of fly-ash cenospheres in the braking materials improved their thermal stability, hardness and impact strength, reduced their density, effectively increased the friction coefficient at medium and high temperatures, and enhanced the heat-fade resistance of the braking materials. The inclusion of fly-ash cenospheres contributed to the formation of surface friction film during the friction process of the braking materials, and facilitated the transition of form from abrasive wear to adhesive wear. At 100-350 celcius, the friction coefficient of the optimal formulation is in the range of 0.57-0.61, and the wear rate is in the range (0.29-0.65) x 10-7 cm3 center dot N-1 center dot m-1, demonstrating excellent resistance to heat-fade and stability in friction coefficient. This research proposes the use of fly-ash cenospheres as a substitute for environmentally harmful and expensive copper in brake materials, which not only improves the performance of braking materials but also reduces their costs.

Abstract ：
The surface of TC11 titanium alloy was polished and strengthened using ultrasonic rolling process (USRP) technology. The effects of USRP on the surface quality, friction and wear properties, corrosion resistance, and wear mechanisms of TC11 titanium alloy at room temperature, low temperature (-60 degrees C), high temperature (400 degrees C), and in corrosive environments were investigated by using optical microscope, microhardness tester, electrochemical workstation, multifunctional friction and wear tester, SEM, EDS, XRD, and XPS. The results indicate that USRP can effectively refine the surface grains of titanium alloy, reducing its surface roughness parameter by 80.4 % and increasing surface hardness and residual compressive stress by 21.7 % and 97.1 %, respectively. USRP is advantageous for producing a layer of TiO2 on the surface of titanium alloys, effectively enhancing the corrosion resistance of titanium alloy surfaces. USRP technology can improve the stability of surface hardness values of titanium alloys in harsh environments. The results of dry friction and wear tests using GCr15 steel balls as the counter material show that the USRP technology can effectively reduce the friction coefficient and wear loss at room, high and low temperatures. The results of corrosion and wear tests using Si3N4 as the counter material indicate that the USRP technology can effectively reduce the friction coefficient and wear volume in seawater corrosion environments. The USRP technology is most effective in reducing the hightemperature friction coefficient of titanium alloys and improving their wear resistance in low-temperature and corrosive environments. The primary wear form of TC11 titanium alloy after USRP has shifted from adhesive wear to abrasive wear.

Abstract ：
Inertial-based upper limb motion capture technology is widely applied in directly controlling robots through human motions due to its low cost and portability. Most upper limb motion capture models typically focus solely on estimating the wrist position (WP) while neglecting the motion of the wrist. Moreover, these models struggle to precisely estimate joint positions, especially in the presence of magnetic disturbances. In this article, a two-layer upper limb motion capture model is proposed. In the upper layer of the model, a hand center position estimation method (HCPEM) is presented to estimate accurately hand center position (HCP) regardless of magnetic field interference. In the lower layer of the model, an optimized sensor-to-segment alignment algorithm based on physical constraints (OABPCs) is proposed to align sensors and segments with the aim of improving the precision of the estimated HCPs. The UR3 robotic experiment platform was designed to verify the accuracy of the HCPs. For different motion tasks and different mounting positions of the inertial measurement units (IMUs), the performance of the proposed two-layer model was further investigated through experiments. The results show that the HCP estimated by the proposed two-layer model achieves root-mean-square errors (RMSEs) below 2.5 cm for different motion tasks and various IMU mounting positions, even in the presence of magnetic field disturbances. Compared with the existing algorithm, the RMSE of the joint position measurements is improved by 1 cm. This study enables flexible, accurate, and convenient control of the robot through human motion.

Abstract ：
Ti-steel laminated metal composites have been widely used in shipbuilding and the chemical industry due to the superior corrosion resistance of Ti and the favorable mechanical properties of stainless steel. In this paper, Tisteel laminated metal composites without Ti-Fe IMCs have been fabricated by directed energy deposition-arc method using a Cu-Ni transition interlayer. Based on the analysis of microstructure analysis, the crosssectional microstructure can be divided into 304SS / Cu-Ni interface containing (Fe, Cr) and (Cu) solid solution, Cu-Ni deposition layer containing (Fe, Cr) and (Cu) solid solution, and TA2/Cu-Ni interface containing Ti2FeCu and Ti-Cu IMCs. Besides, the Cu-Ni deposition layer contains a small content of recrystallized grains with {100}<100> texture and a large content of deformed grains with{100}<110> texture due to the impact of arc and droplets during continuous depositions. Furthermore, the peak hardness is decreased to 518 Hv and the mean value of compressive shear strength is enhanced to 195.27 MPa, which can be attributed to the elimination of interfacial Ti-Fe IMCs, defect-free microstructure, and residual stress relief. Based on polarization curves and electrochemical impedance spectroscopy, the corrosion resistance reduction of the cross-section is due to the formation of a mass of primary battery systems. Furthermore, based on the thermodynamics calculation of Fe-CuNi, Ti-Fe-Cu, and Ti-Ni-Cu ternary systems, the alloying mechanism is that Ti-based IMCs with lower Gibbs free energy will be formed instead of brittle Ti-Fe IMCs, resulting in the elimination of Ti-Fe IMCs and the formation of less brittle phases at both 304SS / Cu-Ni interface and TA2 / Cu-Ni interface.

Abstract ：
To reveal the internal mechanism of the radial clearance between the inner and outer tubes on the microstructure of the electromagnetic pulse welding joint interface, the formation and evolution mechanism of interface microstructure are studied by changing the radial clearance between the 304L stainless steel and T2 copper tube combined with microscopic characterization and numerical simulation. The study shows that the interface presents a wave shape, which is due to the Kelvin-Helmholtz interfacial instability effect caused by the high-speed collision. As the radial clearance increases from 1.65 mm to 2.15 mm, magnetic intensity maximum, impact speed, impact angle, the length of the wavy unbonded region and the wavelength of the wavy interface increase. Meanwhile, the stress distribution appears S shape. The interface element distribution is a combination of local high-temperature melting and element interdiffusion at less high-temperature. And the formation of the steel-copper electromagnetic pulse welding joint includes the arcing of upper surface of the outer tube, the fragmentation of the end of the outer tube, the generation of unbonded areas and the generation of bonded areas. The reason is that the outer tube undergoes different plastic deformation under the combined effect of the propagation direction, the sound wave, and the reflected wave of the shock wave. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.

Abstract ：
In this paper, inertia friction welding (IFW) is used to enable a high-quality and efficient joint between 2205 duplex stainless steel and 316 L stainless steel. Specifically, stainless steel bars (2205/316 L) with a diameter of 35 mm and length of 120 mm are used. In addition, the effect of IFW speed on the microstructure and properties of welded joints is assessed using scanning electron microscopy, electron backscattered diffraction, energy dispersive X-ray spectroscopy, microhardness test, and tensile tests. The results indicate that dynamic recrystallization of the microstructure of joints occurs during IFW welding, which causes grain refinement. The diffusion of Ni from the 316 L base metal to the 2205 base metal, as well as the diffusion of Cr from the 2205 base metal to the 316 L base metal, results in a strong metallurgical bond between the two materials. In addition, the microhardness of the welding area exceeds that of the base metal (the closer to the weld zone, the greater the microhardness value). The tensile strength of the joints initially increases with increasing IFW speed, but then it starts decreasing beyond a certain point. The optimal welding parameters for achieving high-quality joints between 2205 duplex stainless steel and 316 L stainless steel are as follows: axial pressure = 5 MPa, rotational inertia = 4.17 kg.m(2), and IFW speed = 2700 r/min.

为揭示内外管径向间隙对电磁脉冲焊接头界面微观组织的内在作用机理，本文通过改变304L不锈钢与T2紫铜管的径向间隙，结合微观表征和数值模拟，深入研究微观组织演化机理。研究表明，试样界面呈现倾倒波浪状是高速碰撞引起的开尔文-亥姆霍兹界面失稳效应造成的。随着径向间隙由1.65 mm增加到2.15 mm，磁场强度峰值、碰撞速度及碰撞角度增加，界面微观组织的未结合区域增加，波浪状界面波长变大，且应力分布呈现S型。界面元素分布是局部区域高温熔化和较高温度下元素互扩散的综合作用引起的。接头形成过程包括外管上表面弧形化、外管端部的破碎化、未结合区域以及结合区域的形成四个阶段，其原因是在冲击波、反射波以及冲击波传播方向的综合叠加作用下，金属管不同部位发生了不同的塑性变形。

Abstract ：
Duplex stainless steel was formed through welding wire and arc additive manufacturing (WAAM) using tungsten inert gas. The effects of wire feeding speed (WFS), welding speed (WS), welding current, and their interaction on the weld bead width and height were discussed. Back-propagation (BP) neural network algorithm prediction model was established by taking the bead width and height as the output layer, and the network weight and threshold values were optimized using the particle swarm optimization (PSO) algorithm to obtain the prediction model of bead width and height. The predicted results were verified by experiments. Results show that the weld bead width increases with the increase in WFS and the welding current and decreases with WS. The smaller the WFS, the faster the WS, which is beneficial for the generation of equiaxed crystals. The smaller the welding current, the faster the cooling speed of the metal melt, which is conducive to the formation of dendrites. The interaction among WS, wire feed speed, and welding current has a significant effect on the bead width. The weld bead height is positively correlated with the wire feed speed and negatively correlated with the WS and current. The interaction between the wire feed speed and WS is significant. The optimized WAAM process parameters for duplex stainless steel are a wire feed speed of 200 cm/min, WS of 24 cm/min, and welding current of 160 A. The maximum error of the BP neural network in predicting the weld bead width and height is 7.74%, and the maximum error between the predicted and experimental values of the BP-PSO neural network is 4.27%. This finding indicates that the convergence speed is fast, improving the prediction accuracy.
