| Abstract: | In order to develop an environment-friendly method to form a chemical conversion film on aluminium surface without the toxic hexavalent chromium compounds, a process with sodium molybdate and potassium permanganate as the oxidants in the treating solution has been investigated. Solution components and preparing parameters have been optimized. Micro-structure and components of the conversion film have been studied by various micro-analysis methods, and the growth mechanism of the chemical conversion film has also been investigated. |
