Abstract
A low wear coating formed on a metal substrate to serve as a high temperature rubbing seal layer, comprising a surface layer made fundamentally of a wear resistant metal oxide such as nickel oxide and a solid lubricating material such as calcium fluoride and at least one intermediate layer made fundamentally of the metal oxide optionally with the addition of the lubricating material, wherein at least an outmost intermediate layer as well as an inmost region of the surface layer is impregnated with a brazing solder. The solder is added in the form of powder to the material of the intermediate layer prior to a flame spraying process and later caused to melt and permeate into the surface layer formed by flame spraying.
