Titanium alloy screw is a kind of very active metal, its equilibrium potential is very low, in the medium, its thermodynamic corrosion tendency is high. However, titanium screws belong to machinery and industry equipment industry, it can be divided into fasteners, connectors, which has been recognized by the majority of customers products. After processing of the thread surface of titanium screws, it has special glue, which greatly enhanced the anti loosing characteristics of the screw. The internal fixation with plate and screws has been established for many years, and the development of the internal fixation technique has improved.

In order to improve the corrosion resistance of titanium, oxidation, electroplating, plasma spraying, ion nitriding, ion implantation and laser processing surface treatment technology is studied, which can protect the titanium oxide film and obtain the desired corrosion resisting effect. In order to meet the need of metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high temperature wet chlorine gas and high temperature chloride, a series of titanium-molybdenum, titanium, titanium-palladium molybdenum-nickel and other corrosion resistant titanium alloys have been developed. Ti -32 Mo alloy is used for titanium castings.

Applications: titanium and titanium alloy screws are widely used in industrial electroplating, chemical industry, light industry, textile, medical and petrochemical fields.
