For us, metal, is a very familiar material, the author of daily life, a very wide range of USES, and we use metal history, is quite long. As early as 3-4000 years ago, we ancient people began to use iron products as tools.
With the development of society, smelting technology also develops slowly. There are more and more kinds of metal products with better performance. All kinds of alloys we use in modern times are characterized by high hardness, light weight and strong corrosion resistance, which play a great role in the modernization of society. So many alloys, there is an alloy, better performance, is also a very wide range of USES, that is titanium alloy.
It is the lightest and strongest metal on earth. It has developed rapidly, mainly due to the development of military industry.
As mentioned above, titanium alloy, with excellent performance, is mainly used in the military field at the beginning of development, and the military field has very high requirements on materials, because the operating environment of fighter aircraft and other equipment is very demanding. Pure titanium has the highest strength-to-weight ratio of any metal on earth. It's as strong as steel, but 45% lighter. At present, titanium alloy products, mainly used in aircraft engines, aircraft fuselage, rockets and so on. The airbus A380, the world's largest passenger plane, contains 70 tonnes of titanium, mainly used in engines. In the submarine, is also very widely used, such as Russia's famous "typhoon" class nuclear submarine, with a large number of titanium alloy. Of course, titanium alloy can reduce the weight of the body, but the cost is relatively high.
Titanium products, however, will not have such a problem, we do not need to apply a layer of anti-rust agent. Because titanium is coated with a thin layer of titanium dioxide (TiO2), it actually protects the underlying titanium from any type of corrosion, including electrochemical, microbial, and stress corrosion.
Due to this feature, make titanium alloy products, is a good way to play a role in all kinds of high corrosion environment, as previously mentioned the submarines, perennial soak in water for submarines and other naval vessels, and the water is rich in all kinds of ions, corrosion resistance is strong, general metal products will soon be corrosion, the titanium alloy was don't have to worry about the problem.
