Wear and Abrasion Resistant Surface Coating

Hardness, wear and abrasion resistance are the key characteristics of Hardide which have been extensively tested in the laboratory and proven in industrial environments.

Under abrasion testing (ASTM G65) Hardide is up to four times more wear resistant than HVOF Tungsten Carbide with a wear rate 40 times lower than abrasion resistant steel AR-500 and 12 times lower than Hard Chrome. 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 is homogeneous and binder-free which eliminates particle pullout and improves wear and erosion resistance.
