METHOD FOR APPLYING A DIAMOND LAYER ON SUBSTRATES MADE OF SINTERED METALLIC CARBIDE

摘要

The present invention relates to a method for increasing the adhesion of diamond layers which are applied on substrates made of sintered metallic carbide. This method comprises submitting the substrate made of sintered metallic carbide to a first selective etching using WC and to a subsequent coselective etching, and priming the formation of germs using diamond powder before the diamond layer is applied.
