“…In consideration of the fact that the top surface becomes smooth owing to thermal flow by fluidization phenomenon, and due to a decrease in the viscosity of electrodeposition coating resin at baking, we can consider the result of the decreased surface roughness to be quite reasonable. 35) However, in the case of DAF, the surface roughness did not decrease, but became from Ra ¼ 6:8 to Ra ¼ 7:2. No decrease in the surface roughness Ra was observed following application of electrodeposition coating on DAF.…”

In this study, we compared and examined the corrosion resistance of the magnesium alloy with the composite film of 2 kinds of coating on 3 kinds of surface treated film as the substrate treatment. 3 kinds of surface treated film stands for conventional DOW17 anodized film (DAF), chemical conversion treatment JISA3-type MX3 film (CCF), which contain hexavalent chromium, fluorine and phosphorus compounds, and environmentally friendly silicate anodized film (SAF) containing no hazardous substances and 2 kinds of coating stands for organic coating and electrodeposion coating. As a result of the analysis, we could observe that it was extremely effective for magnesium alloy AZ91D to apply the composite film of environmentally friendly SAF with cationic electrodeposition coatings to obtain superior corrosion resistance to that of the composite film of conventional DAF or CCF with organic spray coating. At the same time we could take an action for the environment countermeasure by using the environmentally friendly SAF with the water base cationic electrodeposition coatings as a countermeasure for VOC (Volatile Organic Compound) regulations.
