Improving the Attachment and Wear Resistance of Diamonds in Tools

Abstract

It is expedient to use an adhesive coating with insular structure to bind diamonds in tools. The vacancies in the defective sections of the diamond surface are saturated with metal atoms. The reliability of diamond retention may be assessed by applying cyclic dynamic loads to simulate the forces on the diamond in tool operation. The influence of a titanium–nickel coating on the diamond retention and the wear resistance of the diamond tool is investigated.
