| Abstract: | The macroscopic appearances of the Ni based metal powder melted under the laser clad are supplied and analyzed. For the idea characteristcs of the reinforce functional layer on aluminium surface obtained by laser clad, the key parameters among the laser, the contains and size of the powder and the matrix material that will be reinforced must be very important. The results show that the surface of the matrix material can be reinforced because of the right formulation of metal powder and laser technological parameter. |
