HVOF Tungsten Carbide Coating Properties, Structure And Applications WC-Co tungsten carbide coatings are probably the second most widely used wear resistant coatings after WC-10Co-4Cr.Kermetico HVAF and HVOF tungsten carbide coatings have excellent resistance to sliding wear, abrasion and erosion despite lower corrosion resistance than WCCoCr.The Kermetico HVAF WCCo coatings are gas-tight (non-permeable to gas and liquid) at 50 microns | 2 mils.
