Title CUBIC BORON NITRIDE COATING METHOD AND MATERIAL PRODUCED BY THE METHOD
Abstract Disclosed is a method for coating a substrate containing an iron-group transition metal such as a WC-Co super-hard alloy with a film of cubic boron nitride (cBN), which involves a preliminary step of forming a boride or silicide of an iron-group transition metal on the substrate. The process enables the production of a coated material in which crystalline cBN is coated at a high adhesion degree.
