Influence of Deposition Parameters of the Ti-Al-N/Zr-Nb-N-Cr-N Multilayered Nanostructured Coating Obtained by the Arc-PVD Method on Their Physicomechanical, Tribological, and Operational Properties

摘要

Physicomechanical, tribological, and operational properties of the Ti-Al-N/Zr-Nb-N-Cr-N multilayered coatings obtained by the arc-FVD method are investigated. Dependences between the controlled deposition parameters (the bias potential across the substrate and the revolution rate of the sample relative to sputtered cathodes) and the characteristics of the coatings having hardness up to 37 G Pa and adhesion strength of over 100 N are established. Comparative investigations into the tribological properties of multilayered coatings of various compositions showed that the developed coatings are characteristic of the lowest friction factor. A cutting tool with such coatings possesses high resistance properties in conditions of the interrupted and continuous cutting of gray cast iron (SCh30) and steels (St. 45, X18H10T).
