Abstract
The technology and composition of electroless composite (Ni-B)-SiC plating on Al-Si alloy (LG12) substrate were studied.The single factor which affects the coating deposition was explored.As a result,the best processing and parameter of electroless composite (Ni-B)-SiC plating were found out.And the structure and performances of the composite electroless coating were analyzed.The result shows that dispersion particles can not change the original amorphous structure on the whole.And after heat treatment at 450 the coating emerges tiny crystal and its Vickers hardness (HV) reaches the maximum of 1473.[
