| Abstract: | The morphology, chemical composition and phase structure of SIMOXIDE chromium-free chemical conversion coating on Mg alloy were introduced. The formation process and electrochemical characteristics of the conversion coating were described. The production process was presented. The chemical conversion film possesses low electrical resistance, high adhesion to paint and excellent corrosion resistance. The major performances of the conversion coating reach and even exceed those of the traditional chromate conversion coating. |
