“…It is obvious that the measured friction coefficients of the AlTiN-Cu and AlTiN-Ni coatings are lower than that of the AlTiN coating. The metallic Ni and Cu phases in the AlTiN-Cu and AlTiN-Ni coatings may provide lubricant effects during the sliding process [15]. The friction coefficient was measured as the ratio of the tangential force to the normal force.…”

“…The incorporation of Cu(Ni) into TiAlN coatings has also been studied. Cu(Ni) forms as crystals, rather than dissolving into the TiAlN matrix because Cu(Ni) is mutually immiscible with TiAlN and because its nitride is thermally unstable [15]. TiAlN coatings doped with Cu (Ni) have been shown in previous studies to eliminate the columnar crystal structure, and to both decrease a coating's friction coefficient and increase its toughness [15][16][17][18][19][20][21].…”

In this study, three kinds of coatings, AlTiN, AlTiN–Ni, and AlTiN–Cu were deposited via the cathodic arc evaporation method. The microstructure, mechanical properties, oxidation resistance, and cutting behavior of these coatings were then investigated. The incorporation of Cu(Ni) into AlTiN eliminated its columnar structure and led to an increase in the growth defects of its macroparticles. The addition of Cu and Ni decreased the hardness of the coatings, their elastic moduli, and their friction coefficients. All of the AlTiN, AlTiN–Ni, and AlTiN–Cu coatings presented sufficient adhesion strength values. The oxidation resistance of these three coatings was determined to be in the following order: AlTiN > AlTiN–Ni > AlTiN–Cu. Titanium turning experiments indicated that the cutting force was reduced and the tool life was improved through doping with Cu(Ni) elements, dependent on cutting speed. The AlTiN–Ni coating showed the best performance at a high cutting speed, whereas the AlTiN–Cu coating was more successful at a lower cutting speed.

Películas delgadas de ZrTiSiNiN fueron depositadas sobre sustratos de vidrio y silicio mediante co-sputtering reactivo con magnetrón usando blancos de Ti5Si2, Zr. En esta investigación se varío el contenido de Ni en los recubrimientos mediante la adición de cubos de Ni ubicados sobre el blanco de Zr. La morfología superficial, la estructura cristalina y el espesor de las películas fueron evaluadas mediante microscopía electrónica de barrido (SEM), difracción de rayos X (XRD) e interferometría respectivamente. La resistividad eléctrica se midió mediante el método de cuatro puntas y sus propiedades ópticas se caracterizaron por espectroscopía ultravioleta / visible (UV/Vis). Con base en los resultados de XRD se observó que el Níquel actúa como refinador de grano al lograr disminuir el tamaño de cristalito de 27 nm hasta 15 nm cuando la concentración de Níquel aumenta de 0 at% a 6,8 at%. Tanto la resistividad eléctrica y el “band gap” óptico de los recubrimientos aumentaron con la disminución del tamaño del cristalito como resultado del aumento de la densidad de límites de grano y del efecto de confinamiento cuántico.

The macrostressed state of (Ti,Al)N–Cu and (Ti,Al)N–Ni ceramic–metal coatings obtained by the arc-PVD method has been studied using X-ray diffraction and by measuring the radius of curvature of a coating–base composite sample (Stoney’s method). It is established that the presence of a tough metal phase favors significant reduction in the level of macrostresses in these structures as compared to those in (Ti,Al)N ceramic coatings, the absolute values of which decrease from 4.7–4.3 to 0.17–0.32 GPa. At the same time, both Ti–Al–Cu–N and Ti–Al–Ni–N coatings retain high hardness of 43 and 51 GPa, respectively, versus 29 GPa for Ti–Al–N coatings. The obtained results give grounds to suppose that the high hardness of the ceramic–metal coatings studied is determined by their nanocrystalline structure rather than by compressive macrostresses.
