主　　题：mechanical coating technique photocatalytic activity TiO_(2) milling time oxidation temperature 

摘      要：The titanium coatings were prepared on Al_(2)O_(3) balls by mechanical coating technique (MCT),and then the coatings were oxidized to titanium oxides(TiO_(2)) films at 300-600 ℃.The effects of different milling time and oxidation temperature on thickness of films were *** composition and microstructure of the films were analyzed by scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS).The results show that the thickest coatings with an average thickness of 20 μm were obtained at the milling time of 15 *** addition,with the increase of the oxidation temperature,the oxidation of the film is *** the milling time is 15 h,the oxidation temperature is 500 ℃,and the addition of photocatalyst is 1 g/*** films have the best photocatalytic performance when the degradation rate of methyl orange solution reaches the maximum value of 74.9 %,and the films have a good reusability.
