Anodizing technology of titanium and titanium alloy
Anodizing technology of titanium and titanium alloy
With the social and economic development and the continuous emergence of various new technologies, as well as the continuous expansion of the application fields of titanium and alloy, the research on the surface treatment technology of titanium alloy has been strengthened around the world in the past ten years. The preparation of nano particles on the surface of titanium and its alloys by anodic oxidation process to improve the wear resistance, corrosion resistance and biocompatibility of titanium alloys has become one of the research hotspots in the current field.
The anodic oxidation film of titanium and titanium alloy has higher hardness, strength, corrosion resistance and wear resistance than that of titanium and its alloys, can prevent oxygen permeation, and can present various colors. It is an ideal protective layer and decorative layer. To realize the anodic oxidation of titanium and titanium alloys, the surface of titanium materials needs to be cleaned in advance. In this way, the color will be shiny and bright.
The surface oxidation treatment of titanium and titanium alloy can produce a variety of colors, including gray, brown, brown, purple, ultramarine, dark blue, sea blue, gray blue, yellow, rose red, light yellow, green and more than ten kinds of color films, and the surface of the film is flat, smooth, continuous, uniform, dense, and firmly combined with the base metal. At the same time, it is basically applicable to TC4, TC1, TC2, TA1, TA2 and other titanium alloys, and can be used for process decoration and marking.
With the improvement of people's living standards, the demand for colored titanium is becoming increasingly urgent. Therefore, in terms of the color of titanium products, it is also necessary to use anodic oxidation coloring technology.
