| Abstract: | The mass transfer processing is studied by SEM, EDS and ICP-AES. The results are that there are a lot of procedures in micro-arc oxidation. One procedure is that some elements in the matrix diffuse into the coatings and then into electrolyte. The second procedure is that the ions in electrolyte diffuse into coatings and then into matrix. The mass transfer processing has important influence to the growth of MAO coatings, which can affect the element distribution and the phase growth. |
