| Abstract: | Ce-Mn conversion coating was prepared on AZ91 magnesium alloy at room temperature by dipping the specimens into solutions containing Ce(NO3)3,KMnO4 and fluoride.The surface morphology,composition and corrosion resistance of the conversion coating which was treated for various time were investigated.The results show that Ce-Mn conversion coating can be formed rapidly at room temperature by adding a little fluoride.The conversion coating which is mainly composed of Al,Ce,Mn and O elements is integrated and un... |
