Tungsten carbide coatings replace chromium
hardness of HVOF tungsten carbide coatings is greater than 70 Rc (Rock-well scale) compared with typical values of 60 to 70 Rc for hard chrome plating. Microhardness values for the tungsten carbide coating are on the order of 1050 DPH 300 (Diamond Pyramid Hardness) compared with values of 750 to 850 DPH that are typ-ical of hard chrome plate.

Difference Between Aluminum Oxide and Silicon Carbide
Dec 20 2017 · Silicon Carbide The melting point of silicon carbide is 2 830 °C and it has no boiling point since it sublimes. Thus the melting point is actually the sublimation temperature of silicon carbide. Conclusion. Both aluminum oxide and silicon carbide are inorganic compounds. Although aluminum oxide is naturally occurring on earth crust silicon

Silicon Carbide SiC Material PropertiesAccuratus
Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
