Depositing carbide coatings, pref. on cutting tool substrates

Coating is formed, by: evaporating a carbide-forming material (I) in a vacuum arc discharge; and bombarding the substrate surface with ions of (I) so that the surface becomes cleaned and heated to a temp. at which the ions of (I) are carburised by the C content of the substrate and form a condensed...

Zusammenfassung:	Coating is formed, by: evaporating a carbide-forming material (I) in a vacuum arc discharge; and bombarding the substrate surface with ions of (I) so that the surface becomes cleaned and heated to a temp. at which the ions of (I) are carburised by the C content of the substrate and form a condensed carburised coating. (I) is pref. Ti (alloy) TiN or a double source of Ti and Mo.
