Protective coating, a coated member having a protective coating as well as method for producing a protective coating

摘要

The invention relates to a protective coating, having the chemical composition CaSibBdNeOgHlMem, wherein Me is at least one metal of the group consisting of {Al, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W, Y, Sc, La, Ce, Nd, Pm, Sm, Pr, Mg, Ni, Co, Fe, Mn}, with a+b+d+e+g+l+m=1. According to the invention, the following conditions are satisfied: 0.45≦a≦0.98, 0.01≦b≦0.40, 0.01≦d≦0.30, 0≦e≦0.35, 0≦g≦0.20, 0≦l≦0.35, 0≦m≦0.20. The invention relates also to a coated member having a protective coating, as well as to a method for producing a protective coating, in particular a multilayer film for a member.
