Abstract
A direct method for composite coating of Ni/SiC on aluminium is described which consists of a minimum number of operating sequences such as degreasing, electrolytic etching in HCl, plating in a Watts nickel bath containing SiC suspension followed by a heat treatment. The picking conditions were optimized and the effect of current density and SiC particle content in the bath on the vol. % inclusion of SiC in the deposit is studied. Results of hardness and wear rate of the deposit with respect to vol. % inclusion was discussed
