Abstract. A new method for assessing the hardness of materials by testing their samples for wear by the chord method (“block-on-ring”) is proposed. It is based on the principles of determining hardness with stationary hardness testers and results of a previously performed analysis of the correlation dependence of Mohs hardness on the material resistance to wear. Such dependencies are obtained by measuring the wear segment chord from cutting a disk into a flat sample for a selective set of materials in a wide range of hardness.
