摘要

摘要:在6061铝表面电沉积Ni-α纳米Al2O3颗粒。本研究优化的电沉积条件分别为40°C、2 A/dm2、6 g/L的温度、电流密度和粒子浓度百分比。进一步扩展田口法，对L27正交参数阵列优化得到的优化条件进行优化研究，得到涂层温度为40℃、电流密度为1.75 A/dm2、颗粒浓度为4.5 g/L时，涂层耐磨性较好。颗粒的分散更加均匀，很少有枝晶结构的镍晶体。图形抽象

Study on dry sliding wear behaviour of nanocomposite coatings – an extended Taguchi’s method

ABSTRACT Electrodeposition of Ni-α nano Al2O3 particle was carried out on Aluminium 6061. The study optimized electrodeposition conditions were found to be 40°C, 2 A/dm2, 6 g/L of temperature, current density, and percentage of particle concentration respectively. Further Taguchi method was extended to fine tune the optimized conditions obtained by L27 orthogonal array of parameters for modified study which resulted in better wear resistance with coating conditions of 40°C, 1.75 A/dm2 and 4.5 g/L of temperature, current density and percentage of particle concentration respectively. The dispersion of particles was found more uniform with very few nickel crystals with dendrite structure. GRAPHICAL ABSTRACT
