METHOD FOR DIAMOND-COATING SURFACES

摘要

The invention relates to a method for coating surfaces with diamond from the gaseous phase, wherein the surface to be coated is pre-treated in an atmosphere consisting of hydrogen and a hydrocarbon at a high temperature in a high-frequency discharge, followed by coating by deposition of diamond from the gaseous phase. A very high diamond nucleation density is achieved with said pre-treatment even on electric insulating substrates.
