Abstract

There are still some challenges to use metal matrix composites reinforced with diamond particles in grinding field because it is difficult to find a suitable metal matrix to balance the mechanical properties and grinding performance. In order to solve this problem, CuSnFeSn/diamond composites were fabricated by introducing hybrid microwave sintering with diamond concentration ranging from 40 to 70%. The microstructure, physical and mechanical properties, and critical grinding performance were investigated. Best balance of mechanical properties and grinding surface roughness occurred when the diamond concentration is 60%. It holds a hardness of 98.5 ± 0.5HRB, a flexural strength of 266.98 ± 15.6 MPa, an elastic modulus 46.62 ± 8.48GPa, and WC sample surface roughness Ra14.92 ± 2.92 nm. The grinding experiment results reveal that there are three wear modes in the processing, which are adhesive wear, plastic deformation, and sliding friction.
