Influence of Ultrasonic on the Property of Electroless Plating Ni-Cu -P Alloy Coating at Low Temperature
The action mechanism of ultrasonic was investigated when the ultrasonic wave as a new kind of energy importation way was introduced in the technology of electroless plating at low temperature. Compared with common electroless plating coatings, influence factors of improving the properties of the Ni-Cu-P Alloy coating under ultrasonic were analyzed through hardness, dense nitric acid spot testing metallographic structure observation and EDS. Experimental results show that, under the effect of ultrasonic, the obtained Ni-Cu-P coating has more fine crystal grain, even and dense surface morphology. Its corrosion resistance and hardness have been improved obviously.
