Abstract
The paper reports on the enhanced hardness of nanocomposite coatings, their thermal stability, protection of the substrate against oxida- tion at temperatures above 1000 °C, X-ray amor- phous coatings thermally stable above 1000 °C and new advanced nanocomposite coatings composed of small amount of nanograins dispersed in an amorphous matrix which, due to low values of the effective Young's modulus E* satisfying the condi- tion H/E* > 0.1, are very elastic and exhibit strongly improved tribologi...Morecal properties; here E* = E(1 – ν2), E is the Young's modulus and ν is the Poison's ratio. Trends of next development of hard nanocomposite coatings are outlined.
