WebAug 16, 2024 · Metal-based diamond cutting tools are widely used for sawing and grinding hard-brittle materials, such as stone, concrete, and ceramics [ 2 ]. Currently, the main strategies for manufacturing the metal matrix diamond tools include traditional hot pressure sintering (CHPS) and conventional pressureless sintering (CPS) [ 3, 4 ]. Diamond is a metastable state of carbon and starts converting into graphite at ≈700 °C in air; high sintering temperatures should then be avoided to prevent oxidation and graphitization. Alternatively, diamond grits can be protected by a coating to withstand the sintering conditions.
