摘要
在普通Ni-P-SiC化学镀工艺基础上,添加纳米SiC微粒,采用超声波分散工艺,基于单因素试验结果,进行三因素五水平二次正交旋转组合试验,探索试验参数对复合镀层性能的影响规律。结果表明:镀液pH=6±0.5,施镀温度为(86±1)℃,镀液中纳米SiC浓度为3 g/L时,所获得的复合镀层经480℃热处理后显微硬度达1700 HV,复合镀层耐磨性最好。
On the basis of technology of general Ni-P-SiC electroless plating, nano-partiele SiC was put into Ni-P solution by strong scattering action of ultrasonic. Based on the results of single factor experiment, the authors investigated the influence regularity of preparation process parameters （temperature, pH value, the concentration of SiC nanopartieles） on coating by the method of quadratic orthogonal rotation combination design test with three factors and five levels. When the temperature is 86℃, pH value is 6±0.5 and concentration of SiC nanoparticles is 3 g/L, the hardness of the coating is over 1700HV after heat treatment, and the wearability is the best.
