Anodizing technology of titanium and titanium alloys

With the development of society and economy and the emergence of modern technologies, as well as the continuous expansion of titanium and alloy applications, the research on titanium alloy surface treatment technology has been strengthened all over the world in recent decades. Nanometer preparation on titanium and alloy surface by anodic oxidation process to improve the wear resistance, corrosion resistance and biocompatibility of titanium alloy has become one of the research hotspots in the current field. Titanium Tube Supplier says the anodizing process is a process that uses electrolysis to form an oxide film on the surface of the metal. It is a method of forming oxygen on the anode in an electrochemical manner and reacts with the titanium surface of the anode to form an oxide film. Its simple operation, easy to control, by adjusting the anodizing parameters voltage, current, electrolyte concentration can be obtained with different structures and different chemical properties of the anodizing, thereby expanding the application field of titanium and titanium alloys, so as to improve the performance of titanium and titanium alloys in an effective way. The anodized film of titanium and titanium alloy has higher hardness, strength, corrosion resistance and wear resistance than titanium and can prevent oxygen infiltration, and can show a variety of colors, is the ideal protective layer and decorative layer. To realize the anodizing of titanium and titanium alloy, it is necessary to wash the surface of titanium materials in advance. Then the color will shine brightly. Titanium and titanium alloy surface oxidation treatment can produce a variety of colors, which are gray, brown, brown, purple, ultramarine, dark blue, Marine blue, gray blue, yellow, rose red, light yellow, green and other ten kinds of color film, and the surface of the film layer is smooth, smooth, continuous, uniform, dense, and firmly combined with the matrix metal. At the same time for TC4, TC1, TC2, TA1, TA2 titanium alloy basic application, can do process decoration and marking. With the improvement of people's living standard, the demand for colored titanium is increasingly urgent, so in the color of titanium products themselves, they also need to use anodic oxidation coloring technology.
