摘要
用化学镀的方法制备了Ni-P-纳米SiC复合镀层,并采用正交试验方法研究了Ni-P-纳米SiC复合镀的工艺中颗粒含量、超声时间、搅拌转速对镀速和硬度的影响。结果表明:随着颗粒含量和转速的增加镀速先上升后下降;随着颗粒含量和超声时间的增加硬度先增大后减小;在此基础上确定了其最佳工艺参数为SiC含量2 g.L-1,超声时间30 min,搅拌转速200 r.min-1,在此条件下复合镀层显微硬度为714.81 HV,镀速为10.2 mg/(cm2.h)。
Ni-P-SiC nanometer composite coating was prepared by electroless plating method.The effects of SiC concentration,ultrasound time,stirring speed in process of electroless Ni-P-SiC nanometer composite coating on deposition rate and hardness were studied by way of orthogonal experiments.With the increase of SiC concentration and stirring speed,the deposition rate of coating firstly increased and then decreased.With the increase of SiC concentration and ultrasound time,coating hardness firstly increased and the...
