Abstract In this paper, the microstructures and rolling contact fatigue behaviors
of laser cladding Inconel 625 coatings with or without post-heat treatments were
analyzed. The results revealed that the fatigue resistance of the laser cladding
coating after any post-heat treatment was worse than that of the as-deposited coating. First, through the finite element analysis, the distribution of stress along the
thickness direction of the coating was obtained, and it was concluded that the
bonding interface between the coating and the matrix had little effect on the fatigue properties of the coating. Then X-ray diffraction (XRD), scanning electron
microscopy (SEM) and energy… More >
