Abstract: A corrosion resistant aluminum alloy abradable coating for use as a seal material consists of a porous base metal alloy layer containing corrosion inhibiting metal compounds dispersed throughout the porous base metal alloy layer. A method of forming a corrosion resistant aluminum alloy abradable coating consists of co-thermal spraying aluminum alloy powder plus polymer powder and particles containing corrosion inhibiting metal compounds.
