Les outils de coupe devant supporter des contraintes au cours de leur emploi en usinage, nous etudions des outils qui non seulement resistent a l'usure mais conservent aussi leurs proprietes mecaniques -- aptitude a supporter la coupe interrompue, le choc thermique, et des charges cycliques, aussi bien que la resistance a l'usure. Dans le present travail, nous comparons les resultats d'essais de rainurage et de fraisage effectues avec des metaux durs de type ISO K25 et ISO K35 revetus par les procedes de revetement C.V.D. et P.V.D. Les revetements C.V.D. sont TiCN ou une combinaison de TiN et TiC . A titre de comparaison, les memes substrats ont ete revetus de TiN ou (Ti,Nb)N par deux procedes P.V.D.Because cutting tools must withstand the ...
