The surface morphology, the structure and composition as well as the corrosion resistance of the prepared silane composite fihn were investigated by SEM, AFM, XPS and electrochemical test. The experimental results showed that the structure of the silane composite film was composed of Si-O-Si three-dimensional network doped with ZrO2 showing excellent corrosion resistance, because the structure of this kind of composite film has much less micropore which improves the uniform and density of the silane film.展开更多

It was shown that the picking-up of the zinc coating on die strengthened with the increasing of friction factor which was originally affected by the coating's structure. Duing forming, (00X) planes (X= 2, 4) preferential orientation of zinc deposits increased, which resulted in enhanc ing the coating's friction behaviors. Therefore, the forming mechanism of electrogalvedzed deposit was demonstrated that both friction and the stricking -up behaviors of the coating are intensified simultaneously and affect each other.展开更多
