Titanium is a metal with a strong passive tendencies. Dielectric oxide film of titanium at temperatures below 315 ℃ always maintain this characteristic. In order to improve the corrosion resistance of titanium, developed oxidation, electroplating, plasma spraying, ion nitriding surface treatment technology, ion implantation and laser processing of titanium oxide film played a role in enhancing the protection, access to the desired corrosion resistance effect. For sulfuric acid, hydrochloric acid, methyl amine solution, the high temperature and high temperature chloride wet chlorine produced in the need for metal materials, development of a titanium - molybdenum, titanium - palladium, titanium - molybdenum - and a series of corrosion resistant nickel titanium alloy.
-32 Titanium castings using a titanium-molybdenum alloy, for often pitting or crevice corrosion environments using titanium -0.3 -0.8 partial molybdenum-nickel alloy or titanium equipment -0.2 using titanium-palladium alloy, have received a very good use effect. Good heat resistance of titanium wire, new titanium or long-term use at higher temperatures 600 ℃.
