The wear behaviour of electro-codeposited Ni-SiC composites

In this study, attempt has been made to investigate the wear resistance of Ni-SiC composites manufactured by electro-codeposition process, which is significantly correlated to the vol.% SiC in the matrix. In addition, the vol.% of SiC is closely related to the concentration of submicron SiC and the surfactant in the bath. It is found that the surfactant CTAB can not only disperse the SiC particles well in the electrolyte therefore leading to better homogeneously distributed SiC particles in the matrix but also enhances the SiC vol.% embedded in codeposition layer. It is confirmed that the wear resistance of codeposited layer increases with increasing submicron-size vol.% SiC. (C) 2002 Published by Elsevier Science B.V.
