| Abstract: | Using laser cladding technology on the surface of 45 steel, iron-based powder coating was prepared. In the certain range of craft parameter, the micmstructure of cladding zone and combination zone were analyzed, the law of change was found. The results show that the lair power and .scanning speed have regularity influences on microstructure and resistance wear of iron-based laser cladding coating. Finally, p =2.5 kW,v =3 -4 mm/s was determined as the best craft parameter. |
