Abstract

La pièce mécanique à surface antiabrasion est caractérisée en ce qu'elle comprend un corps métallique fritté obtenu par métallurgie des poudres et un revêtement en cermet déposé par la technique au laser. Le revêtement a une certaine épaisseur dont une portion est métallurgiquement liée au corps métallique. Le dépôt par laser permet de fondre en surface la pièce frittée à revêtir sous l'effet du faisceau laser. La surface de la pièce frittée à recouvrir est donc fusionnée sur une épaisseur pouvant aller de 10 .mu.m à 1mm, ce qui permet la fermeture des pores en surface, typique aux pièces frittées et, par conséquent, l'accroissement de sa résistance au choc. De plus, la faible surface couverte à un instant donné par le laser permet l'autotrempage de la zone exposée, suite au déplacement du faisceau, par effet de puits de chaleur du volume métallique environnant. Le revêtement obtenu selon la présente invention présente aussi une très faible porosité à cause de la fusion complète des poudres de la pièce frittée par le laser.
