摘　　要：为寻求新的能量输入方式、在降低施镀温度的前提下改善化学镀层的耐蚀性能,将超声波技术引入化学镀工艺制备了N i-P化学镀层,利用孔隙率测试方法、扫描电子显微镜、X射线衍射仪、动电位极化曲线及交流阻抗等手段,分析了镀层的孔隙率、组织结构和形貌以及镀层的耐腐蚀性能,并将超声波化学镀层与常规化学镀层进行了性能比较。结果表明,超声波技术的应用能有效地降低化学镀层的孔隙率,提高镀层的耐腐蚀性能。Ultrasonic technology was used to prepare electroless Ni-P coating.The porosity,microstructure,morphology,and corrosion resistance of the coating were investigated making use of porosity measurement device,scanning electron microscope,X-ray diffractometer,dynamic potential polarization curve measurement device,and electrochemical impedance spectroscope.And a comparison was made between the ultrasonic electroless Ni-P coating and conventional electroless Ni-P coating.It was found that the ultrasonic electroless Ni-P coating had a decreased porosity and increased corrosion resistance than conventional electroless Ni-P coating.
