| Abstract: | Ni-coated Nano-Al_2O_3 powder with different propotions are put in the surface of stainless steel and cladded by the 7kw CO_2 laser . The structure and properties of the coating are studied by SEM and. other equiments . results show the dispersed Nano- Al_2O_3 strength the surface and their wear resistance increase by 2-3 time . |
