Abstract:Ti-6Al-4V alloy composite membrane for internal combustion engine was prepared by adding SiC particles into micro arc oxidation electrolyte. The microstructure and friction properties of the composite film were studied by SEM and friction-wear test. The results show that many net micropores form on the surface of the sample without SiC. When the SiC content is lower than 5.0 g/L, uniform microporous structure forms on the membrane surface. With the increase of SiC content to 7.5 g/L, the number of pores in the membrane layer decreases. The membrane layer and the substrate of Ti-6Al-4V alloy is bonded well and almost no crack is found. Moreover, partial pore structure forms in the interface area of the membrane layer. The film thickness decreases with the increase of SiC content. The friction coefficient decreases first and then increases with increasing SiC content, many grooves with larger width and depth form in the alloy matrix. The wear mechanism is abrasive wear.
