In order to reach the purpose of using pre-laser cladding method preparation of Ni-based amorphous alloy coatings on 45 steel substrate surface by the method was carried out. The principles of the three clusters and the amorphous line of the law of composition rules were used. The Ni59.35Nb34.45Sn6.2 alloying powder which has a great glass-forming ability in conventional preparation methods of amorphous alloys was chosen. In the protection of atmosphere, the amorphous surface coating was prepared. The microstructure, micro-hardness and performance of the different output power of the laser cladding were analyzed.
