Powdermetallurgically fabricated diamond grinding tools for the machining of concrete and natural stones have a high demand regarding their abrasive behavior and wear resistance. Because of the high hardness of the synthetic diamond grits used, which are embedded in the metal matrix, the main focus lies on the wear behavior of these diamonds. Especially the break out, respectively the retention of the diamond grains during the machining process influences the cutting performance of the tools directly. Therefore, an important research topic focuses on the interface reactions between the metallic binder and the diamond surface. The addition of small amounts of carbide forming metals such as Cr or Ti, completely inhibit graphitization and lead to a strong carbidic interface with a chemical bonding of the diamonds. Based on these results, this paper focuses on the influence of carbide forming elements on the wear performance and diamond retention.
