Abstract
NOVELTY - In the CVD of composite gradient layers containing diamond and carbide phases in the presence of a gaseous hydrocarbon, a carbide forming metal is transformed from the solid phase to the gaseous phase by evaporation from an electrically heated crucible or a hot wire containing the metal and/or by electron bombardment. USE - The process is useful for applying composite gradient layers containing diamond and carbide phases for wear protection of tools and components. ADVANTAGE - Control of carbide formation is improved compared with prior art processes.
