Wear-resistant Blades for Decanter Centrifuges

Titanium-based cermet is a composite material sintered from ceramic hard phases and metal binder phases via powder metallurgy technology. It not only possesses the characteristics of ceramic materials, such as high hardness, high wear resistance, corrosion resistance, high-temperature resistance and oxidation resistance, but also retains the favorable toughness of metal materials as well as good physical electrical and thermal conductivity. Meanwhile, its density is less than half of that of tungsten steel, endowing it with advantages in cost reduction and energy conservation.

    Low density: The density is only about 50% of tungsten cobalt hard alloy, and the quantity of products per unit weight is twice that of tungsten cobalt hard alloy.


    High strength: The bending strength is comparable to tungsten carbide.


    Energy saving: The weight of products with the same quantity is significantly reduced, which lowers the energy consumption of equipment operation.
