【Abstract】 Micro/nano multi-scale structure on the surface of 45 steel was prepared by using the anodic oxidation process and the effect of temperature and oxidant on 45 steel surface morphology was analyzed. Its surface properties were studied by the thermal shock resistance test and vulcanized test. The results show that when the temperature decreases,the formation of micro/nano structure gets slowly,multi-scale nanostructure is less. Adding oxidant,the reaction rate increases, surface nanostructure is being disorder and uneven distribution;vulcanization fouling gets less,surface corrosion is also lighter.更多还原
