VERFAHREN ZUM BESCHICHTEN VON SINTERMETALLCARBID-SUBSTRATEN MIT EINER DIAMANTSCHICHT

摘要

A method for coating a sintered metal carbide substrate with a diamond film is disclosed, which comprises subjecting the substrate to a selective tungsten carbide etching step; subjecting the substrate to a selective Co etching step; and subsequently coating a desired section of the substrate with the diamond film, and where after completion of the selective tungsten carbide etching step and prior to diamond coating the substrate is nucleated with diamond powder through friction contact.
