  • The inhibiting effect of Cr coating on diamond oxidation in diamond/Al-borosilicate glass composites was studied. Coated diamonds with different Cr layer thickness was sintered with Al-borosilicate glass at the same process. The samples were tested and observed for volume expansion rate, bending strength and section morphology. The single particle compressive strength of sintered diamonds and the composition at the interface were analyzed. Results show that Cr coatings could protect the diamond through both isolation and consumption of oxygen, which effectively inhibits the oxidation of diamonds. Meanwhile, the thickness of coating layer has significant influence on diamond oxidation. If the coating is too thin, it could not continuously protect the diamond during high temperature sintering. If the coating is too thick, there would be cracks and flake spalling on it due to the thermal stress mismatch, exposing the diamond to oxygen environment and failing to protect. For 140/170 diamond, the optimum coating thickness is 1.58 μm.
