Effect of laser power on microstructural evolution and wear-corrosion resistance of laser-cladded Fe-based alloy on 40Cr steel surface

Fe-based alloy cladding layers were fabricated on 40Cr steel substrates by laser cladding. The effects of different laser powers (2100, 2200, 2300, and 2400 W) on the phase composition, microstructure, microhardness, wear resistance, and electrochemical corrosion behavior of the...
