Abstract
This work gathers a comparative study of the mechanical and tribological behaviour (microhardness under load, Young modulus, elasticplastic properties, friction and wear coefficients) of TiN/CrN and TiN/AlTiN multilayers deposited by conventional industrial PVD techniques. PVD multilayers with about between 50 nm individual layer thickness were deposited on flat samples of Co-cemented WC achieving a total thickness of about 2 microns. Mechanical and Tribological tests include microhardness under load at final loads between 10 mN aand 750 mN, Young modulus calculations and friction and wear tests.<br><br>El presente trabajo recoge un estudio comparativo de las propiedades mecánicas y tribológicas (microdureza, fluencia, módulo elástico, coeficientes de fricción y desgaste), de multicapas TiN/AlTiN y TiN/CrN depositadas mediante técnicas industriales de PVD. Las capas, de espesores comprendidos entre 25nm y 100nm, se depositaron secuencialmente sobre substratos de WC, hasta obtener un espesor total de unas 2 micras. El estudio mecánico y tribológico comparativo incluyó ensayos de microdureza a cargas entre 10 mN y 750 mN, módulo elástico, comportamiento frente a fluencia y coeficientes de fricción y desgaste.
