| Abstract: | According to the criteria for forming ability and the law of cluster line of amorphous composition,an alloy of Ni_(60)Zr_(20)Nb_(15)Al_5,which has a great glass-forming ability(GFA) in preparation by conventional methods,was chosen to prepare coatings on 45 carbon steel surface by laser cladding.The microstructure,mechanical and corrosion property of the coatings prepared with different laser power were studied.The results showed that the clad coating could be differentiated in a clad zone,a transition zone... |
