Hardness (Wear Resistance)

The hardness of Fine Ceramics is generally indicated using a Vickers hardness number. The method for measuring the hardness of Fine Ceramics is defined in JIS R 1610 (ISO 14705: 2000). Vickers hardness is a resistance value obtained by pressing a diamond indenter onto a test specimen. Extreme hardness is the primary feature that endows Fine Ceramics with their superior wear resistance. This has led to the use of Fine Ceramics in a wide range of applications, including pump components, cutting tools, seal rings, bearings and a multitude of wear-resistant components for industrial equipment.
