The invention relates to the technical field of
film coating, in particular to a method for rapidly preparing a colorful
titanium oxide thin film on the surface of substrate material. The method comprises the following steps: at first, a layer of
titanium film is sprayed on the surface of the substrate material through the magnetron
sputtering technology, then, the substrate material is put into an
electrolytic cell which has been set up, the
electrolytic cell is filled with
electrolyte, the to-be-coated substrate material is put on the
cathode, and a stainless steel plate is hung on the
anode. Generation and color of the
titanium oxide thin film are controlled through changing the
voltage of the
electrolytic cell, so that the titanium film on the surface of the substrate material generates oxidizing reaction to generate a layer of colorful
titanium oxide thin film to protect the titanium film. The
electrolyte can be recycled and meets the requirements of
environmental protection and industrial production; and in addition, the generated
titanium oxide thin film can alleviate abrasion, scratch and contact
corrosion of titanium, so that the problems about maintenance and abrasion during the using process of titanium are solved. With adoption of the method, the
titanium oxide thin film can be rapidly prepared on the surface of common substrate material, and in addition, the colorof the titanium
oxide thin film is easy to control and uniform. The thickness of the titanium oxide thin film prepared through the method is slightly influenced by the material shape.
