Abstract
A monolayer diamond tool is made by coating diamond abrasive particles with a carbide-forming metal and then brazing the coated diamond to a tool substrate.
Claims12
A method of making a diamond cutting or abrading tool comprising the steps of:
- (A) pre-coating diamond particles with a carbide-forming metal;
- (B) heating the pre-coated diamond of step (A) to a temperature sufficient to form a metal carbide coating thereon;
- and
- (C) brazing the coated diamond with a braze which alloys with said metal carbide coating.

A method of making a diamond cutting or abrading tool comprising the steps of:
- (A) pre-coating diamond particles with a carbide-forming metal powder comprising molybdenum;
- (B) heating the pre-coated diamond of step (A) to a temperature sufficient to form a molybdenum carbide coating thereon;
- and
- (C) brazing the coated diamond with a braze which alloys with said molybdenum carbide coating and which comprises from about 1% to about 20% molybdenum.

A method of making a diamond cutting or abrading tool comprising the steps of:
- (A) pre-coating diamond particles with a carbide-forming metal powder comprising iron;
- (B) heating the pre-coated diamond of step (A) to a temperature sufficient to form an iron carbide coating thereon;
- and
- (C) brazing the coated diamond with a braze which alloys with said iron carbide coating and which comprises from about 1% to about 10% iron.
