【Abstract】 The technological characteristics of laser cladding of Ni-Cr alloy of Al alloys and some properties of the cladding layer are reported, it is found that the cladding layer has a smooth surface, a thickness of 1 mm, and a highest microhardness with HV680. Moreover, the abrasion resistance of the cladding layer is 9 times as high as that of the Al alloy substrate.更多还原
