Titanium and titanium alloy is widely used in various industries
Titanium material because of its affinity to oxygen at large, can produce a layer of dense oxide film in the surface, can make the titanium element is not subject to the medium, so it is particularly strong corrosion resistance.
In most aqueous solutions, dititanium can produce passivated oxide film on the surface.
Titanium and titanium alloy in acidic, alkaline, saline solution because of the generation of passivation oxidation film, so has a good stability, than stainless steel and other non-ferrous metal corrosion resistance are better, because of its excellent corrosion resistance and affinity, titanium has been widely used in many industries.
1. Chemical industry
Titanium has good stability in various acid, alkali and salt media.
For example, the use of titanium anodes and titanium wet chlorine coolers in the chlor-alkali industry has a good economic effect.
2. Oil industry
Titanium has very strong stability in organic compounds.
Therefore, titanium is an excellent structural material in petroleum refining and chemical industry, which can be used to make various titanium heat exchangers, titanium reactors, titanium high pressure vessels and titanium distillation tower.
3. Metallurgical industry
(1) titanium is an active metal with good inspiratory property and is an excellent degassing agent in the steelmaking industry. Titanium can precipitate oxygen and nitrogen in the cooling process of the combined steel, which can make the steel tough and elastic.
(2) titanium has good corrosion resistance and stability in acidic solution containing metal ions. Therefore, titanium electrolytic plate has been widely used in the electrolytic production of non-ferrous metals such as copper, nickel, cobalt and manganese in the hydrometallurgical industry.
4. Chemical fertilizer industry
Urea is an important chemical fertilizer, which is highly corrosive at high temperature. The use of titanium equipment can greatly increase the service life of the equipment and reduce the maintenance time.
Therefore, titanium equipment is used in urea production.
5. Desalination and shipbuilding
Titanium has excellent resistance to seawater corrosion, and has special stability in both stationary and high-speed seawater.
Therefore, titanium is the ideal material for seawater desalination plant.
Titanium has strong resistance to seawater and Marine air corrosion, strong strength and light weight, making it an ideal structural material for shipbuilding industry.
6. Power industry
Titanium has good stability in hot water containing chloride, sulfide and many other corrosive properties. Replacing cu-ni alloy pipe with titanium pipe can greatly improve service life and reduce maintenance time, and the economic effect is very significant.
7.The health care industry
Medical titanium can resist the corrosion of human body, and harmless to human body, has good biocompatibility and good comprehensive mechanical properties.
As a result, medical titanium is widely used in the medical device and pharmaceutical industry sectors, as well as in human implants.
