Titanium Equipment Analysis: Titanium And Gas Reaction Can Produce Magical Effect
Mar 18, 2017

Titanium on the liquid and solid can not produce a reaction, can not be combined, Wang Shui also can not do it, however, titanium is very much on the gas, like with nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, methane and many other gas combination. Titanium of this feature can produce magical, for our use.


Presumably we all enjoy the festive night colorful fireworks, right? There is a lot of money here! When the titanium powder and oxygen quickly combined and burned, can produce a strong high temperature and glory. Fireworks can not only enhance the joy of the atmosphere in the festival, but also as a military signal bombs, used to indicate the target or to convey the order. Adding an appropriate amount of titanium compound to the arc lamp increases its brightness. The use of titanium on the strong absorption of air, you can remove the air, causing a vacuum. For example, the use of titanium made of vacuum pump, you can put the air to only one hundred thousandths of a million. In the metallurgical industry, add a small amount of titanium to steel or other metals, "eat" inside the gas and impurities, can play a good role in deoxidation and nitrogen removal, but also to eliminate the harmful effects of sulfur, thereby improving the steel and The mechanical properties of other alloys improve their corrosion resistance.


Industrial pure titanium is classified according to the content of impurity elements


Titanium has many distinct advantages: low density (4.5kg / m3), high melting point (1660 ℃), strong corrosion resistance, high specific strength, good plasticity, but also through the alloying and heat treatment method to create high mechanical properties Of the various alloys, is the ideal aerospace engineering structural materials. Containing a certain amount of oxygen, nitrogen, carbon, silicon, iron and other elements of the α-phase titanium impurities. It has excellent stamping process performance, good welding performance, is not sensitive to heat treatment and organization type, and has certain strength under satisfactory plastic condition.


Industrial pure titanium is classified according to the content of impurity elements. Its strength depends mainly on the gap element oxygen, nitrogen content. It has high corrosion resistance in seawater, but is poor in inorganic acids. Generally used in the manufacture of -253 ~ 350 ℃ temperature work, the force is not a variety of sheet parts or forgings, but also the manufacture of rivet wire and pipe. Application examples: In addition to industrial use of industrial pure titanium manufacturing parts, the extensive use of titanium alloy. It has been widely used in the aerospace, aerospace, chemical, shipbuilding and other industrial sectors, manufacturing gas turbine components, making prosthetic devices and other biological materials.


Titanium alloy density is generally about 4.5g / cm3, only 60% of steel, pure titanium strength is close to the strength of ordinary steel, some high-strength titanium alloy than the strength of many alloy structural steel. So the titanium alloy specific strength (strength / density) is much larger than other metal structure materials, see Table 7-1, can produce a unit of high strength, good rigidity, light weight zero parts. At present the aircraft engine components, skeleton, skin, fasteners and landing gear and so on are using titanium alloy.


Titanium alloy is a new type of structural material, it has excellent overall performance, such as the density is small (4.5gcm-3), specific strength and toughness than the fracture toughness, fatigue strength and crack resistance, good toughness, good corrosion resistance, corrosion resistance Excellent, some titanium alloy maximum operating temperature of 550 / C, is expected to reach 700 / C. So it is in the aviation, aerospace, chemical, shipbuilding and other industrial sectors have been increasingly widely used, the rapid development. (Σ0.2 / density) of light alloy, steel and so on, the ratio of titanium alloy is higher than that of other light metals, steel and nickel alloy, and this advantage can be maintained to about 500 / C, so some titanium alloy Suitable for the manufacture of gas turbine components. I produce titanium rods, titanium plate: TC4, TA0, TA1, TA2, TC3 titanium production in about 80% for the aviation and aerospace industry. For example, the United States B-1 bomber body structure materials, titanium alloy accounts for about 21%, mainly for the manufacture of fuselage, wing, skin and bearing components. F-15 fighter body structure materials, titanium alloy consumption of 7000kg, about 34% of the weight of the structure. Boeing 757 aircraft structural parts, titanium alloy about 5%, the amount of up to 3640kg. MacDonald Douglas / company's DC10 aircraft, titanium alloy consumption of 5500kg, accounting for more than 10% of the weight of the structure. In the chemical and general engineering areas of titanium consumption: the United States accounted for about 15% of its output, Europe accounted for about 40%. Due to the excellent corrosion resistance of titanium and its alloys, good mechanical properties, and qualified tissue compatibility, making it for the production of prostheses and other biological materials titanium application Titanium in military applications


Titanium is the post-World War II to the late 40s to 50 years and industrial production and gradually developed a high-performance important structural materials. From the earliest application, is for the military aviation industry to provide high-performance materials. With the development of national military industry, titanium applications are constantly widening. So far, titanium has been in aerospace, nuclear energy, ships, weapons and many other areas of access to more and more applications, as an important strategic metal materials. Its application level has also become a measure of a country advanced state of weapons and equipment, reflecting a country's military level and military strength of the important indicators.
