摘要
采用正交实验方法,对金刚石表面金属化进行研究,重点考察了硫酸镍浓度、次磷酸钠浓度、施镀时间、pH值、施镀温度等因素对镀层质量的影响。研究表明:硫酸镍浓度是显著性影响因素,得出了最佳的镀镍工艺参数。对比研究了不同金刚石粒度对金刚石/铜复合材料热导率的影响,发现随着金刚石粒度增大,复合材料的热导率也增大。
A research on surface metallization of diamond was carried out by orthogonal experiment method to investigate the influences of factors such as concentration of nickel sulfate,concentration of sodium hypophosphite,plating time,pH value and plating temperature on the coating quality.Results showed that the concentration of nickel sulfate was a significant influencing factor.Then the optimum nickel plating process parameters was obtained.Meanwhile,the effects of different diamond particle sizes on the thermal conductivity of diamond or copper composite material were compared.It is concluded that the thermal conductivity of composite materials was increasing with the increase of diamond particle sizes.
