Abstract (en)
[origin: EP2537959A1] A coating layer comprises multilayer film (3) consisting of sublayers (4-7) of different hardness. The multilayer film comprises repeated sequence of hard and soft sublayers. The outermost sub-layer is a hard layer. The layer (2) with high hardness is formed using dispersed particles containing cobalt-molybdenum chromium silicon alloy, cobalt-chromium-tungsten-silicon alloy, metal (M)-chromium-aluminum-yttrium alloy, their oxide, nitride and/or boride (M is iron, cobalt or nickel). An independent claim is included for manufacture of coated component (1).
