What are the main oxide ceramic material? Oxide ceramics are commonly used ceramic coating material. Classified according to their composition, mainly alumina oxide, ho Department, titanium, chromium, mullite, spinel ceramics. Have a high melting point oxide, mostly above 2000 ℃. The vast majority oxide in an oxidizing atmosphere is stable, mostly oxides having heat insulating properties and electrical insulating properties, strength characteristics in a high temperature environment. Most important feature of ceramic oxide ceramic coating process on thermal spray process, it can be sprayed, does not require a vacuum or protective atmosphere conditions directly in the atmosphere, which for equipment manufacturing, paint shop has a great design and cost benefits . Therefore, the oxide ceramic thermal spray technology has become the most widely used, up to the amount of the ceramic coating material. An oxide-based ceramic thermal spray coatings wide range of applications of ceramic coating, including the use of its chemical properties and corrosion candle metallurgy petrochemical, metallurgy, etc; use the wear resistance of the machinery, transportation field; use of its heat engine in the field of aerospace thermal barrier properties; and other utilization of electrical insulation, magnetic shielding, a solid electrolyte, infrared radiation and other properties of functional coatings fields. Thermal spray technology is currently in the country has made more widely applied ceramic coating technology, the development trend in recent years, and is characterized by: (1) a large area of ??long-term protection technology has been widely used for the steel structure long-term exposure to outdoor atmosphere pieces, spraying lead, zinc and alloy coating instead of the traditional method of high temperature ceramic paint spraying, make long-term implementation of cathodic protection of atmospheric corrosion, have developed rapidly in recent years. Such as television towers, bridges, road infrastructure, water gates, microwave towers, high-voltage transmission towers, underground cable bracket, buoy floating drums, Vertical Shaft and other large projects have adopted the spray of lead, zinc and its alloys for corrosion protection methods. Currently there are dozens of specialized coating plant working in this area, spraying an area of ??several million square meters per year. This technology is not only widely promoted in the country, but also in foreign aid projects has also been a good application. (2) thermal spray technique to repair and strengthen the large imports of key equipment and parts made in recent years in this area there are many examples of successful application. Such as: seven meters mill, high speed fan rotor, large extruder embolism, large gears, electrode extrusion spray, high power automotive crankshaft, etc., carry out these tasks, namely, the urgent need to solve the production; the second is to save a lot of foreign exchange . (3) the application of technology HVOF thermal spray technology as China's development and improvement of the quality of coating layer requirements are also increasing. In recent years, the United States and other countries to develop a high-speed gas (HVOF) method is a new process for the preparation of high-quality coatings. Because HVOF method has many advantages, currently has successively introduced from abroad nearly piece of equipment in the industrial sector plays an important role.
