| Abstract: | The craft and microstructure of laser cladding on copper alloy surface were studied. The result indicated that a non-crack tin bronze coating which has a metallurgy union with the substrate was obtained on the brass substrate by using the optimal laser power and scanning velocity. And the clad coating has a character of rapid solidification structure. The distribution of the structure is fine butcher shape crystal, thick branch crystal , thin branch crystal and butcher shape crystal from the bottom to the top of the cladding coating. |
