Titanium is strong, and the tensile strength of pure titanium can reach the highest
180kg/mm2. Some steels are stronger than titanium alloys, but the specific strength (the ratio of tensile strength to density) of titanium alloys exceeds that of high-quality steels. Titanium alloy has good heat resistance, low temperature toughness and fracture toughness, so it is mostly used as aircraft engine parts and rocket and missile structural parts. Titanium alloy can also be used as fuel and oxidant storage tanks and high-pressure vessels. Titanium alloys have been used to make automatic rifles, mortar seat plates and recoilless gun launch tubes. In the petroleum industry, it is mainly used for various containers, reactors, heat exchangers, distillation towers, pipelines, pumps and valves. Titanium can be used as electrodes and condensers in power stations and environmental pollution control devices. Titanium-nickel shape memory alloys have been widely used in instruments. In medical treatment, titanium can be used as artificial bones and various appliances. Titanium is also a deoxidizer for steelmaking and a component of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints. Titanium carbide and titanium hydride are new types of cemented carbide materials. Titanium nitride has a color close to gold and is widely used in decoration.
Titanium and titanium alloys are widely used in the aviation industry and are called "space metals"; in addition, they are increasingly widely used in the shipbuilding industry, chemical industry, manufacturing mechanical parts, telecommunications equipment, and cemented carbide.
In addition, because titanium alloy has good compatibility with the human body, titanium alloy can also be used as artificial bone.
Corrosion resistance of titanium Zirconium is a kind of chemical material used in the atomic energy industry and used as a corrosion-resistant chemical material under high temperature and pressure, but its activity in solution is second only to sodium.
Then, add a lively solution of zirconium nitrate to the titanium hydroxide solution, and you will find that titanium excludes zirconium nitrate.
As you can see, there are obvious layers in the picture, with zirconium nitrate on the top and titanium hydroxide on the bottom.
We know that the density of titanium hydroxide is less than that of zirconium nitrate, but it can still maintain obvious stratification and keep zirconium nitrate on the upper layer, which proves the corrosion resistance of titanium.
According to experiments, titanium will not be corroded when placed on the seabed for 20-50 years.
