Ni-based alloy flame sprayed-welding layers refusioned under different laser processing parameters, microstructure and phase identity in different temperature drawing temper were investigated using optical microscope (OM), scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The hardness test and wear resistance were also performed. The experimental results show that the phases of the remelted flame sprayed-welding layers mainly consist of γ-(Ni,Fe), Cr23C6, Cr7C3, Cr2B, CrB, Cr5B3, Fe3B and Fe2B. Compared with the flame sprayed-welding layers, microstructure of the remelted sprayed-welding layers are further refined, hardness and wear resistance are obviously enhanced. Under the same technological conditions, microstructure would be more compacted and finer, hardness and wear resistance would be higher with the quicker laser scanning speed, but the penetration of the remelted sprayed-welding layers is relatively shallower. The hardness of the remelted sprayed-welding layers after different temperature drawing temper is increased furtherly and the hardness of the remelted sprayed-welding layers after drawing temper of 600 ℃×3 h with the scanning speed of 360 mm/min is the highest. It indicates that adopting appropriate laser refusioning treating technology and subsequently heat treatment, Ni-based alloy flame sprayed-welding layers would be further strengthened and service performance would be further improved.
