Ni-SiC nano composite coatings were prepared on pure copper substrate. The surface morphology and distribution of nanometer particles of the composite coatings were observed by scanning electron microscope (SEM), micro-hardness of coatings was tested by HXD-1000 microharder. The results showed that microstructure of Ni-SiC nano composite coating is different from that of electrodeposited nickel coatings. Its electrodepositing process abided by the principal of adsorption. By adding nanometer particles, the structure of composite coatings can be effectively fined, microhardness of composite coatings is improved apparently by comparing with that of electrodeposited nickel coatings. Abrasion resistance of Ni-SiC nano composite coatings is excellent.

The objective of this work is the characterisation of the composite deposits Ni-Cr2O3 on copper substrate; these deposits are obtained from bath of electro-deposition of Nickel watts. The different electrodeposited layers are characterized by various analytical techniques such as adhesion quality, corrosion tests, Vickers microhardness, morphology by scanning electron microscopy Followed by EDX microanalysis and X-ray diffraction. The corrosion tests are realized in a solution of 3.5 % NaCl using lost mass method, polarization and impedance spectroscopy techniques. It was found that the composite coatings Ni-Cr2O3 have an homogeneous and compact morphology, well crystallized and exhibit a high degree of codeposition of Cr2O3 particles incorporated in the nickel matrix. The co-deposited films have very good hardness, adhere perfectly to the substrate and are more resistant to corrosion.
