Problems solved by technology

However, in these methods, the emission and storage of harmful gases in chemical vapor deposition limit its application; the laser-assisted deposition equipment is complex and costly, and is not suitable for large-scale applications; although the cost of multi-arc ion plating is low, its stability is poor, arc light The number of large droplets ejected at the moment of discharge is large, which increases the number of large particles in the film and seriously affects the quality of the film.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a method for quickly preparing a colored titanium oxide film on the surface of a base material. Background technique [0002] Titanium has been widely used in the aviation and aerospace industry because of its high specific strength and good corrosion resistance. However, its full utilization is limited by its tendency to be prone to wear, abrasion and contact corrosion. In order to prevent and reduce the wear, abrasion and contact corrosion of titanium, anodic oxidation can be performed on the surface of titanium and its alloys to form an oxide layer on the surface. [0003] The color of titanium oxide film is colorless and transparent. Titanium metal is oxidized as the anode loses electrons in the electrolytic cell. In the initial stage of oxidation, a dense oxidation barrier layer will be formed on the surface of the titanium film, and the fluorine ions in the electrolyte and...
