| Abstract: |
| Using electroless plating process, the coating was prepared on the surface of aluminum alloy 6063 to improve braze welding performance. The orthogonal experiment was designed to optimize electroless nickel plating process. The brazing property of coating surface was excellent. SEM and EDS methods were applied to investigate the composition, microstructure and surface morphology of the electroless plating nickel coating. The results show that the optimized process which is in favor of improving the brazing property of the electroless plating nickel coating obviously is as follows : boric acid concentration of 5 g/L, nickel sulfate concentration of 30 g/L, sodium hypophosphite concentration of 30 g/L, temperature of 50℃ . |
