Manufacture and mechanical-tribological assessment of diamond-reinforced Cu-based coatings for cutting/grinding tools

This work proposes the design of laser-textured patterns for development surfaces with high anchor densities capable promoting solid mechanical bonding highly abrasive sintered diamond/carbide-reinforced. Cu-based composite coatings excellent wear resistance. The results show dense and well-adhered onto how higher nucleation TiC/Fe3C on diamond favours its greater within matrix, preventing graphitization, detachment. Reductions above 40% 60% in CoF were observed, under dry conditions, reinforced 10 & 30 wt% diamonds, respectively. Depending percentage used, best glass/coating alumina/coating volume ratios around 20 6. These values would indicate that these performance therefore could be used to make tools grinding and/or cutting glass ceramic materials.
