The characteristics of Ti-TiN-(Ti,Cr,Al)N and Zr,Hf-(Zr,Hf)N-(Zr,Hf,Cr,Mo,Al)N coatings, which have a nanolayer structure of the outer layer, are compared. While the hardness of the Ti-TiN-(Ti,Cr,Al)N coating is higher, it also exhibits increased adhesion when paired with a nickel alloy. As a result, the coefficient of friction of the sample coated with Zr,Hf-(Zr,Hf)N-(Zr,Hf,Cr,Mo,Al)N at is much lower. The study of the tribological properties and wear resistance of coatings in the temperature range of 400 - 900 °C revealed that the Ti-TiN-(Ti,Cr,Al)N coating is characterized by significant adhesion with the Inconel 718 nickel alloy, and the wear rate is due to crack formation. For a sample coated with Zr,Hf-(Zr,Hf)N-(Zr,Hf,Cr,Mo,Al)N, oxidation processes dominate, resulting in the formation of a (Zr,Hf)O2 film on the surface. [ABSTRACT FROM AUTHOR] |
