Abstract

A stannate conversion coating was designed for AM60B magnesium alloys. The influences of temperature and time on the surface morphology and phase composition have been tested using scanning electron microscope (SEM) and X-ray diffraction (XRD), respectively.Additionally,potentiodynamic polarization tests have been used to estimate the corrosion resistance of unprotected and protected AM60B Magnesium alloy with a stannate conversion coating in 3.5% NaCl solutions.Plenty of coating particles form a stannate coating at 80 ,consisting of MgSnO3-3H2O. At different temperature the corrosion potential is nearly the same as -1.31V while with time increase it moves towards to positive and reached to -1.01V .Both of corrosion potentials of stannate conversion coatings are more positive than that of AM60B substrate (-1.48V).
