Silicon Carbide occurs in nature only as the extremely rare mineral moissanite. Synthetic Silicon Carbide has been mass-produced since 1893 for use as an abrasive. Silicon Carbide (SiC) is produced at a high temperature in an electrical resistance arc furnace with quartz (silica) and petroleum coke (carbon) as its primary raw materials. The final product is sharp and friable with outstanding
Dense silicon carbide (SiC) coatings by chemical vapour deposition (CVD) technique Overview Theoretically dense SiC coating processed by chemical vapour deposition (CVD) exhibits superior physical, mechanical, thermal and optical properties with excellent wear, abrasion and chemical corrosion resistance.

Hardest thermal spray coating in the world | …
The answer: Seram Coatings claims it is the first in the world to have developed an anti-corrosion and wear-resistant coating based on silicon carbide, one of the world´s hardest compounds. Because this material has no melting point, it has not previously been possible to use it for coating.
HVOF Sprayed WC-Co, WC-Co-Cr Coatings
Thermal Spray Coatings of WC-Co and WC-Co-Cr Thermal spray coating is a surface modifiion process where molten or softened particles are applied by impact onto a surface such as stainless steel. High Velocity Oxy-Fuel (HVOF) Tungsten Carbide Cobalt (WC-Co) coatings produce extremely dense, near zero porosity and wear resistant surfaces.

Thermal Spray & Fuse -A Thermal Spray Process This technology uses an oxygen and acetylene flame to atomize self-fluxing alloy metal powders into a fine spray of particles. During the 1st phase , these sprayed particles are projected with a thermal spray powder gun/assely onto a previously prepared object surface which builds up to form a solid metal coating.
