Particle impacts cause erosion of leading edges of the compressor airfoils as well as the side or surface of the airfoil beyond the leading edge. Although erosion resistant coatings have been developed and applied on the airfoils during the past decade or two and that have protected the side or surface of the airfoil quite satisfactorily, the erosion of the leading edge is still a serious issue. This Small Business Innovation Research Phase I project explores the feasibility of producing an erosion resistant leading edge of compressor airfoils using advanced surface engineering technologies. The modified leading edges will be tested for erosion and corrosion resistance.
