The concentration of titanium alloy casting in HF and HNO3 in the mixed solution with HF and HNO3 dissolved quantity related, the former molar concentration is high, dissolving capacity of the latter molar concentration is low.
Lower concentration of HF on the dissolution of Titanium amount is small, but can get the surface is smooth, and easy to master the dissolved quantity.
Titanium is a metal having a high degree of chemical activity. However, it emerged in many corrosive media particularly excellent corrosion resistance. The reason is titanium and has a good affinity for oxygen, react with oxygen to produce highly strong and dense layer of oxide film on the surface of the blunt.
