With the economic development of society and the emergence of various new technologies, as well as the continuous expansion of titanium and alloy application fields, in the past decade, the research on titanium alloy surface treatment technology has been strengthened all over the world. Nanometer preparation on the surface of titanium and alloy 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 field.

Titanium and titanium alloy anodized film has higher hardness, strength, corrosion resistance and wear resistance than titanium and can prevent oxygen infiltration, and can show a variety of colors, is an ideal protective layer and decorative layer. To achieve the anodizing of titanium and titanium alloys, it is necessary to clean the surface of the titanium material in advance. So that the color will shine bright.

Titanium and titanium alloy surface oxidation treatment can produce a variety of colors, which are bronze, brown, dark blue, blue, light yellow, golden, magenta, purple red, cyan, green and other more than ten kinds of color film, and the surface of the film layer is smooth, smooth, continuous, uniform, dense, and firmly combined with the base metal. At the same time, TC4, TC1, TC2, TA1, TA2, TA3 and other titanium alloys are basically applicable, and can be used as process decoration and marking.

In 2018, Tianda Aluminum set up a special titanium alloy anodizing division, mainly for the orthopedic implant industry, the current titanium alloy color anodizing technology has been verified by a number of customers in the industry, not only fully in line with the industry requirements of YY/T 1615-2018, but also in appearance standards, is better than other manufacturers in the same industry. With excellent quality and intimate service to win the praise of customers.
