Wear cemented borides

Most of the developments in cemented borides aim at the high wear resistance due to the superior hardness compared to carbide-based hard metals. One of the most important applications are, therefore, the cutting tools where cemented boride have to compete with tungsten carbide, titanium carbonitride, and ceramic materials as well. 

Compares the wear, scuffing, and spalling resistance of sheet-metal dies coated by the following surface-hardening processes uncoated, nitrided, borided, nitrogen ion implanted, chrome plated, sulfiirized, uncoated cemented carbide, TiC -I- TiN by CVD, TiC by CVD, VC by TRD, and NbC by TRD...
