Abstract
Plasma electrolytic oxidizing (PEO) of aluminium alloys is an advanced technique to deposit a thick and hard ceramic coating on a number of low Si content aluminium alloys. The rapid growth in the tribological applications of high Si cast Al-Si alloys has been motivating this study, i.e., development of a PEO coating with high wear resistance and low friction for high Si content cast Al-Si alloys. In this research, the effect of substrate materials (i.e., silicon contents, Chapter 4) and process parameters (Chapter 5) on the PEO coating formation, microstructure, and composition were investigated in details. An oxide/graphite composite coating with low friction and high wear resistance was particularly developed and studied (Chapter 6). Based on the observations of coating surface morphology change during the treatment, a coating growth model on the Si region was developed in Chapter 4. The PEO process had four stages where each stage was corresponding to different coating surface morphology, composition, and phase structure, characterized by different coating growth mechanisms.
