Paper Title:
Effect of Ultrasonic Wave on Ni-P-Al2O3 Electroless Composite Coating on Magnesium Alloy
  Abstract

The coating was obtained by electroless plating Ni-P nano Al2O3 on AZ91D magnesium alloys under ultrasound wave. The metallographic microscope and micro sclerometer were used to characterize the structures and hardness of coating. The results showed that in the optimal conditions, ultrasonic electroless plating can increase the coating hardness value by 170HV and extend the coating corrosion resistance time by 130s; inorder to reach the same corrosion resistance time or hardness value, the temperature under ultrasonic decreases 20°C than that without ultrasonic wave; ultrasonic wave can improve the deposition rate, refine the grains and inhibit the nano particles to agglomerate.
