With the economic development of society and the continuous emergence of various new technologies, as well as the increasing demand for titanium and its alloy products, it is of great significance to study how to continuously improve the wear resistance, corrosion resistance and biocompatibility of titanium alloys. of. Among them, some breakthroughs have been made in anodizing technology, which is often used for surface treatment of aluminum alloy products.
The anodic oxidation process is a process of forming an oxide film on the metal surface by electrolysis, electrochemically generating oxygen on the anode, and reacting with the titanium surface of the anode to form an oxide film. It mainly obtains oxide film coatings with different structures and different chemical properties by adjusting anodizing parameters such as voltage, current, electrolyte concentration, etc., thereby expanding the application field of titanium and titanium alloys.
The process is not only convenient to operate and low cost, but also the anodic oxide film produced by it has the advantages of high hardness, high wear resistance and corrosion resistance, strong oxidation resistance, good durability, smooth surface and uniform and dense structure. It can present a variety of good-looking eye colors, and is an ideal protective layer and decorative layer.
