铜-金刚石复合镀层金刚石颗粒复合量的研究

摘要

Diamond particle content is the key to the performance of diamond composite coating.Selecting different volume fractions of alkyl bromide as the additives, we studied the effect of additive volume fraction on the composite amount of diamond particles and selected the optimum fraction of the addictive.We also studied the influences of current density and diamond particle mass concentration on the amount of diamond particles.The results showed that the composite amount of diamond particles increased first and then decreased with the increase of additive volume fraction with the optimum additive fraction of 0.8 mL/L, and that the composite amount of diamond particles increased continuously when controlling the mass concetration of diamond particles in the range of 2.5~40 g/L.Current density had an obvious effect on the compound amount of diamond particles, which increasing rapidly and then decreasing slowly with the increase of current density.%金刚石颗粒复合量是衡量复合镀层性能好坏的重要指标.选用烷基溴化物作为添加剂,研究不同体积分数添加剂对金刚石颗粒复合量的影响,优选出添加剂最佳体积分数;同时,深入研究电流密度、金刚石颗粒质量浓度对金刚石颗粒的影响.研究结果表明:随着添加剂体积分数的提高,金刚石颗粒复合量先增后减,体积分数为0.8 mL/L时,金刚石颗粒复合量最佳;控制镀液中金刚石颗粒质量浓度在2.5~40 g/L范围,金刚石颗粒复合量不断增加;电流密度对金刚石颗粒复合量的影响较为明显,随着电流密度增大,金刚石颗粒复合量呈现先快速增加后呈缓慢下降趋势.
