ABSTRACT:
A method of forming a diamond coating on an iron-based substrate, comprising: providing an iron based substrate with an outer layer which substantially comprises metal borides; and depositing the diamond coating on the outer layer using a process of Chemical Vapor Deposition (CVD). An outer layer may be formed by deposition, by depositing a metal layer which is capable of being boronized followed by boronizing the metal layer, or by boronizing the iron-based substrate. The invention is also related to the use of an iron-based substrate comprising an outer layer with borides for hosting a CVD diamond coating.
