Reinforcement mechanism and wear resistance of Al2O3/Fe-Cr-Mo steel composite coating produced by laser cladding

The nanometer Al2O3 dispersion strengthened Fe–Cr–Mo composite coatings by crosscurrent CO2 laser on 316L steel were produced. The microstructure and phase composition of the coatings were examined through optical microscopy and X-ray diffraction analyses. Hardness distribution, tensile properties a...
