Translated Title
Preparation of a Solar Thermal Absorbing Ni-Al_2O_3 Film
Translated Abstract
The effects of aluminum substrate treatment,sintering temperature and film thickness on solar absorptance of the Ni-Al_2O_3 composite films were investigated. The optimal coating on aluminum substrates treated by a H_3PO_4-CrO_3 solution after mechanical polishing had a nickel mole fraction of 80%,a sol concentration of 0.8 mol/L. The suitable sitering temperature is 600 ℃. Such prepared film has a good solar absorptance.
