Abstract ：
This study investigated the fabrication of a strengthened Ti-TiO2 material with adding 0.5 wt.% TiO2 nanoparticles via selective laser melting process in comparison with CP-Ti. Through the process parameters optimized by response surface methodology, the Ti-TiO2 material fabricated by SLM showed remarkable tensile strength of 800.6 MPa and elongation of 14%, as compared to the fabricated CP-Ti with tensile strength of 594.0 MPa and elongation of 21%. The x-ray diffraction patterns of fabricated specimens showed the expansion of the hcp-Ti lattice along the c-axis due to dissolved oxygen atoms from the decomposition of TiO2 nanoparticles. The microstructure analysis observed remains of incompletely decomposed TiO2 and TiO phases in SLMed Ti-TiO2 material, which was distinguished from former studies. Consequently, the decomposition behavior of added TiO2 nanoparticles associated with the dissolved oxygen in the Ti-matrix during the SLM process was discussed. Based on the evaluation of both the solution effect of oxygen atoms and the reinforcing effect of undecomposed nanoparticles, the dissolved oxygen from decomposed TiO2 was considered the primary factor in the intensified strength of SLMed Ti-TiO2 material. These results could offer novel insights into the additive manufacturing of high-strength and biocompatible titanium alloy via the SLM process.

Abstract ：
目的 研究稠化剂组分中二元酸和硼酸对润滑脂在摩擦副表面润滑性能的影响.方法 分别建立具有正弦曲面凸峰的粗糙面边界润滑系统模型,以及光滑壁面的反应力场边界润滑系统模型,通过分子动力学模拟方法研究 12-羟基硬脂酸/壬二酸润滑脂体系(A润滑脂)、12-羟基硬脂酸/十二烷二酸润滑脂体系(B润滑脂)和12-羟基硬脂酸/壬二酸/硼酸润滑脂体系(C润滑脂)的承载能力、抗剪切能力、摩擦性能,并对C润滑脂进行成键和摩擦化学反应膜分析.结合润滑脂的微摩擦磨损试验,揭示二元酸链长和硼酸对润滑脂摩擦性能的影响.结果 在加压阶段,随着压力的增加,润滑脂密度增大,且分层现象越明显.当压力 Pz=50 MPa时,组分中含硼酸的C润滑脂在各处的密度均较小,表现出最佳的承载能力.在剪切过程中,C润滑脂始终将 2 个粗糙峰隔开,油膜不破裂,承载能力最高;含长链二元酸的B润滑脂和含硼酸的C润滑脂的最大应力相较于A润滑脂,分别降低了 27.1%、57.1%.同时,C润滑脂的摩擦因数相对稳定,在 0.075～0.095范围内波动,其均值为 0.090,相较于 B 润滑脂和 A 润滑脂,分别降低了 16.7%、22.2%,具有优良的力学性能.摩擦磨损结果表明,在稠化剂组分中添加硼酸后,润滑脂的理化性能得到显著提升,摩擦因数及均值分别为 0.085～0.095 和 0.091,模拟结果与试验结果一致.结论 相较于稠化剂中含短链二元酸的润滑脂,含长链二元酸的润滑脂表现出较好的抗剪切能力和摩擦性能.在稠化剂中添加硼酸后,稠化剂的结构得到强化,润滑脂表现出更为优异的抗磨减摩性能.这是因为在硼酸的作用下,润滑脂中的锂皂和硼酸基团不仅形成了配位键,而且能在固体壁面上形成摩擦反应膜,显著提高了润滑脂的物理化学性能.

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 ：
The surface of the TC11 titanium alloy is significantly strengthened through the ultrasonic tumbling process. The effect of ultrasonic tumbling process parameters on the microstructure and surface roughness of a titanium alloy using multiple techniques are investigated, including OM, white light interferometry, SEM, EDS, and XRD. The hardness, friction, and wear properties of the rolling surface are analyzed using a microhardness tester and a multifunctional friction-wear tester. The results indicate that the surface roughness of the titanium alloy decreases initially and then increases with an increase in rolling power, rolling times, static pressure, reduction, spindle speed, and feed rate. The lowest value is achieved with the following parameters: 660 W rolling power, 5 rolling times, static pressure of 0.20 MPa, reduction of 0.15 mm, spindle speed of 200 r·min−1, and feed rate of 0.10 mm·r−1. With an increase in power, the surface hardness of titanium alloy increases, which leads to a reduction in friction coefficient and wear loss. As the rolling times, static pressure, reduction, spindle speed, and feed rate increase, the surface hardness initially increases and then decreases. Meanwhile, the friction coefficient and wear loss tend to decrease initially and then increase. When the rolling power is set to 990 W, the rolling frequency is 5 times, the static pressure is 0.20 MPa, the reduction is 0.15 mm, the spindle speed is 200 r·min−1, and the feed rate is 0.10 mm·r−1, the hardness reaches its maximum value, while the friction coefficient and wear loss reach their minimum values. Response surface optimization was conducted to obtain the optimal process parameters, including a rolling power of 990 W, rolling frequency of 5 times, static pressure strength of 0.20 MPa, reduction of 0.15 mm, spindle speed of 198 r·min−1, and feed rate of 0.10 mm·r−1. Compared to the surface of the titanium alloy before rolling, the hardness increased by 36.4% from 337 HV to 461 HV, the surface roughness decreased by 89.9% from 1.88 μm to 0.19 μm, and the wear loss decreased by 83.3% from 0.60 mg to 0.10 mg. © 2024 Chinese Mechanical Engineering Society.

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 ：
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.
