At present, the type II oxidation of titanium alloy used in the medical industry is actually a kind of micro-arc oxidation of titanium alloy, which was originally derived from the application in the aerospace field. Its main advantages are: increase fatigue strength, increase wear resistance, increase product self-lubricating ability, strong corrosion resistance, enhance biological compatibility and so on. Due to its excellent performance, it should have many benefits when applied to the medical device industry, whether it is human implants or surgical tools.

At present, Tianda Aluminum mainly uses type II oxidation of alkaline solution system. After the oxidation of products, only a small amount of Na and Si elements will be introduced in addition to the product substrate, and the product performance fully meets the requirements of YY/T 1615-2018, with stable production and qualified quality, providing customers with more choices for products with high performance requirements.
