在钢基体上电沉积镍-纳米和微米碳化硅复合材料。沉积物共沉积技术在常规的瓦特浴中使用，四甲基氢氧化铵（TMAH）作为表面活性剂。通过改变镀液中SiC的量和操作条件，获得了具有不同体积%的SiC的沉积物。对复合材料的耐磨性、耐刮擦性和表面粗糙度进行了测试和比较。它被证实，对于给定的体积%的颗粒在存款，Ni-SiC，纳米复合材料表现出低得多的磨损量和较高的抗划伤性相比，Ni-SiC微复合材料。
Nickel-nano and micro Silicon carbide composites were electrodeposited on steel substrates. Sediment co-deposition technique was used in a conventional Watts bath with Tetra Methyl Ammonium Hydroxide (TMAH) as the surfactant. Deposits with varying volume% of SiC were obtained by varying the amount of SiC in bath and the operating conditions. Resistance of the composites to wear and scratch and their surface roughness were measured and compared. It is confirmed that, for a given volume% of the particles in the deposit, Ni–SiC, nano composites exhibit much lower wear loss and higher scratch resistance compared to Ni–SiC micro composites.
