    • Abstract
  • The microstructure of laser forming repaired 10Cr5NiMoV steel with Inconel 625 powders was analyzed. The tensile strength,corrosion resistance and wear-resisting properties of the repaired component were investigated. The results show that fine dendrites are compactly formed without defects in laser forming repaired zone,the width of heated affected zone is less than300 μm and precipitated phases,Nb C and Laves are distributed between dendrite arm spaces. The tensile strength of the interface between laser forming repair zone and base metal is not less than 854 MPa. The micro-hardness of laser forming repaired zone is higher than that of the base steel. The corrosion resistance of laser cladding layers is 15 times the base metal under salt spray corrosion conditions,and the wearing resistance is 1. 6 times better than that of the base metal.
