Abstract

Cette invention a trait à une électrode (10), pratique à utiliser, pour traitement de surface par décharge. On utilise cette électrode, qui possède les qualités requises de résistance et d'innocuité et qui se désagrège facilement, pour traiter une surface par décharge afin de former un revêtement dur à la surface d'un matériau non traité. Ce dépôt est le fait d'une énergie de décharge produite entre l'électrode et le matériau. Le procédé de production de cette électrode consiste à mélanger du TiC en poudre (11), poudre de carbure métallique, avec du TiH2 (12), poudre d'hydrure métallique, à mouler par compression ce mélange et à traiter à chaud le produit moulé afin de libérer l'hydrogène présent dans le TiH2 (12), ce qui permet d'obtenir du titane (Ti) en poudre (13).
