A method for forming an abrasive surface includes applying an electric current through a plating solution so as to cause an abrasive grit to be deposited onto a workpiece and varying a waveform of the electric current while building up a matrix material at least partially around the abrasive grit.

A repaired oxidation and corrosion resistant coating may comprise a repair material applied to a damaged portion of the oxidation and corrosion resistant coating. The repair material may be free of hexavalent chromium and may be compatible with a plurality of oxidation and corrosion resistant materials that comprise hexavalent chromium. The repair material may be burnished. The oxidation and corrosion resistant coating may comprise hexavalent chromium.

Green repair of oxidation and corrosion resistant coatings

An article comprises a metal alloy substrate and a plated wear interface layer disposed over a surface of the metal alloy substrate. The wear interface layer has a chemical composition including between about 0.005 wt % and about 0.050 wt % of antimony (Sb), and the balance silver (Ag) and incidental impurities.

The present invention relates to a zinc-diffused nickel alloy coating for corrosion and heat protection and to a method for forming such a coating. The coating method broadly comprises the steps of forming a plain nickel or nickel alloy coating layer on a substrate, applying a layer of zinc over the nickel or nickel alloy coating layer, and thermally diffusing the zinc into the nickel alloy coating layer. The coating method may further comprise immersing the coated substrate in a phosphated trivalent chromium conversion solution either before or after the diffusing step. The substrate may be a component used in a gas turbine engine, which component is formed from a steel material.
