Structure and Mechanical Properties of Multilayered Nanostructured TiN/ZrN Ion-plasma Coatings

Multilayered coatings based on TiN/ZrN with different thickness of bilayers were deposited on steel substrates using vacuum arc deposition of a cathodes (C-PVD method). Thickness of bilayer strongly depended on deposition conditions and varied in the range 39 – 305 nm, total thickness of the coatings were 11-19 μm. Mechanical and tribotechnical characteristics of the coatings were investigated in the paper as well as its microstructure. Influence of the bilayer thickness on the properties of the coatings were explored.
