Wear-resisting ceramics is a special corundum ceramics made of AL2O3 as the main raw material, rare metal oxide as the flux, and roasted at high temperature of 1,700 degrees, and then combined with special rubber and high strength organic / inorganic adhesive respectively.
Performance Characteristics
1. Large hardness
Its Rocowwell hardness is HRA 80-90, the hardness is second only to diamond, far exceeding the wear resistance of steel and stainless steel.
2. Excellent wear resistance
According to the determination of powder Metallurgy Institute of Zhongnan University of Technology, its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. Under the same working conditions, the service life of the equipment can be extended by at least more than ten times.
3. Light weight
Its density is 3.6-3.9g/cm3, only half of the steel, which can greatly reduce the load of equipment.
4. Solid bonding and good heat resistance
Wear-resistant ceramic sheet are best use high strength ceramic structure adhesive, which can ensure that the ceramics does not fall off for a long time under high temperature.
Our company can customize a variety of special parts, high precision wear parts and ceramic metal composite parts. Each kind of engineering ceramic material has its own advantages and disadvantages, so it is necessary to fully analyze and study the working conditions of ceramics. In all the ceramic materials, the main use of alumina and silicon carbide ceramics two kinds. Alumina ceramic has a very high resistance to the general corrosion and abrasion, and the highest performance and price ratio, suitable for most occasions. Sintered silicon carbide is only considered at higher temperature, higher toughness and wear resistance.
