A method for coating a component of an aircraft engine with a wear-resistant layer, wherein the component is first coated at least regionally with a nickel- or cobalt-based alloy and subsequently aluminized. Also disclosed is a method for producing a spray powder for producing a wear-resistant layer of a component of an aircraft engine.

Coated articles and methods for applying coatings are described. In some cases, the coating can exhibit desirable properties and characteristics such as durability, corrosion resistance, and high conductivity. The articles may be coated, for example, using an electrodeposition process.

A sintered friction material for brake having a high friction coefficient, with which reduction of the friction coefficient is prevented at high temperature and stable brake performance is maintained. It comprises: a metal matrix of Ni or Ni+Fe (small amount); a solid lubricant (a); and a friction adjusting material (b) including: metal or alloy particles (b1) having an average particle size of 50 μm or more and containing at least one selected from W, Mo, Cr, and FeW; and inorganic particles (b2) containing at least one selected from oxides, nitrides, carbides, and intermetallic compounds. An average particle size d.sub.b1 of b1 and an average particle size d.sub.b2 of b2 satisfy d.sub.b1<d.sub.b2. Dispersing, in the metal matrix, b1 and b2 satisfying particular conditions as the friction adjusting material can produce a geometrical structure (particle structure with a high filling density) suitable for preventing plastic deformation of the sintered friction material.
