AUTOCATALYTIC NICKEL-BORON COATING PROCESS FOR DIAMOND PARTICLES

摘要

A method for preparing coated diamond particles comprising the steps of coating the diamond particles with nickel in the presence of a reducing agent having a pH ranging of from about 6 to 10, and recovering the diamond particles coated with nickel / boron (Ni/B) wherein the Ni/B coating contains less than about 5 wt-% boron content. Coated diamond particles are used in abrasive tools / cutting elements such as grinding wheels, saw segments, drill bits and the like.
