METHOD FOR THE DEPOSITION OF A COATING

The method for depositing a coating, primarily on a substrate made of carbon-containing material of a metal-cutting tool, provides for evaporating a carbide-forming material by means of an arc discharge in vacuum. Then, a working surface of the substrate is cleaned and heated by cathode bombardment,...

Beschreibung
Zusammenfassung:	The method for depositing a coating, primarily on a substrate made of carbon-containing material of a metal-cutting tool, provides for evaporating a carbide-forming material by means of an arc discharge in vacuum. Then, a working surface of the substrate is cleaned and heated by cathode bombardment, which is effected by ions of the carbide-forming material, up to the temperature at which the carburization reaction of the carbide-forming material takes place with carbon of the substrate material. Then, the ions of the carbide-forming material are condensated on the working surface of the substrate. Le procédé de dépôt d'un revêtement, essentiellement sur un substrat constitué en un matériau contenant du carbone d'un outil de coupe de métaux, consiste à effectuer l'évaporation d'un matériau de formation de carbure par décharge en arc sous vide. Ensuite, une surface de travail du substrat est nettoyée et chauffée par bombardement cathodique, effectué par des ions du matériau de formation de carbure, jusqu'à atteindre la température à laquelle la réaction de carburation du matériau de formation de carbure a lieu avec le carbone du matériau du substrat. Ensuite les ions du matériau de formation de carbure sont condensés sur la surface de travail du substrat.
