Abstract
Abstract A method of making a diamond cutting and abrading tool. The method includes the following steps: (A) Mixing molybdenum with a braze which alloys with the carbide forming substance and a temporary binder to provide a coating material; (B) Applying said coating material to a tool substrate; (C) Applying at least a monolayer of diamond particles thereover; and (D) Heating the product of step (C) at a temperature sufficient to initially form a metal carbide coating on the diamond and thereafter to braze the carbide coated diamond to the tool substrate.
