Abstract
In this study,a stannate chemical conversion coating was obtained by using sodium stannate and potassium dihydrogen phosphate solution on Mg-10Li-1Zn.The microstructure,formation mechanism and corrosion resistance of this coating were investigated.Results indicated that the conversion coating was uniform and continuous,which was composed of MgSnO3,Mg3(PO4)2 and SnO.Results of corrosion resistance tests showed that such conversion coatings improved the corrosion resistance of the bare alloys.
