Abstract

An abrasive coating system (16) for a substrate (14) of an airfoil (12) in a turbine engine high pressure compressor, comprising a plurality of grit particles (18) adapted to be placed on a top surface (26) of the substrate (14); a matrix material (20) bonded to the top surface (26); the matrix material (20) partially surrounds the grit particles (18), the matrix material (20) consisting of unalloyed chromium and unalloyed aluminum distributed throughout the matrix material (20), wherein the grit particles (18) extend above the matrix material (20) relative to the top surface (26); and a film of oxidant resistant coating (28) applied over the plurality of grit particles (18) and the matrix material (20).
