Abstract

The article reports on the enhanced hardness of nanocomposite coatings, their thermal stability, protection of the substrate against oxidation at temperatures above 1000°C, X-ray amorphous coatings thermally stable above 1000°C and new advanced hard nanocomposite coatings with enhanced toughness which exhibit (i) low values of the effective Young's modulus E satisfying the condition H/E >0.1, (ii) high elastic recovery W e≥60%, (iii) strongly improved tribological properties, and (iv) enhanced resistance to cracking; here E =E(1-ν 2), E is the Young's modulus and ν is the Poison's ratio. At the end trends of next development of hard nanocomposite coatings are briefly outlined.
