| Abstract: |
| Electroless silver plating on A231 Mg alloys via electroless plating and organic coatings ( organosilicon heat-resisting vamish) was studied. The organic coating was made after simple immersion of the samples in organosilicon heat-resisting vamish. In this method the organic coating acted as the interlayer between the substrate and the silver film. When the reaction started, silver would deposit virtually onto the interlayer. Metallized films-ray diffraction and SEM analysis were used to investigate the morphology of the interlayer and silver film growing process. The silver coatings have a rather perfect crystal structure. Also, the potentiodynamic polarization curves for corrosion studies of the coated magnesium alloys were performed in a corrosive environment of 3. 50-/o wt NaCl at neutral pH (7) . The results reveal: comparing with the substrate, the corrosion resistance of coated A231 magnesium alloys increases greatly. The method proposed in this work is environmentally friendly : non-toxic chemicals are used. In addition, it provides a new concept for the corrosion inhibition of magnesium alloys. |
