Wear & Abrasion Resistant Coating
Hardness, wear and abrasion resistance are key characteristics of Hardide CVD coatings, which have been extensively tested in the laboratory and proven in industrial environments.
Under abrasion testing ASTM G65, the Hardide-T coating is:
- 6 x more wear resistant than HVOF WC-83%/Co-17%
- 24 x better than hard chrome plating
- 30 x better than D2 tool steel
- 46 x better than Stellite 6
- 500 x better than Inconel 718
This outstanding wear resistance is achieved through an optimum combination of coating hardness and toughness. Enhanced hardness protects the coating from ploughing, cutting and fragmentation by hard abrasives. Increased toughness, ductility and compressive stresses of the coating reduces the effects of surface fatigue and prevents micro-cracking - typical wear mechanisms that affect ultra-hard materials.
Unlike HVOF or cemented tungsten carbide materials, Hardide coatings are homogeneous and binder-free which eliminates particle pullout and improves wear and erosion resistance.
