HVOF and HVAF 86/10/4 WC-Co-Cr coatings are used for deposition of wear-resistant coatings which have Excellent resistance to sliding wear, cavitation, abrasion and erosion. HVAF TC Coatings have a high fracture toughness coefficient and offer good fatigue and impact resistance. HVAF and HVOF WC-Co-Cr coatings have good corrosion resistance except in a high pH environment … WC-10Co-4Cr- Tungsten Carbide Cobalt Chrome

HVAF and HVOF WC-Co tungsten carbide coatings exhibit excellent resistance to sliding wear, abrasion and erosion but have slight lower corrosion resistance than WC-CoCr. HVAF WC-Co thermal spray coatings are non-permeable to gas and liquid at even 50 microns. Tungsten carbide WC-12Co layers are resistant to sliding wear, impact, abrasion and fretting at temperatures up … WC-Co Tungsten Carbide
