The development of a conversion coating in a stannate bath on magnesium-based ZC71 alloy and on a metal matrix composite (MMC), comprising a ZC71 alloy matrix and 12 vol% SiC particles, has been studied using weight gain behaviour, measurements of corrosion potential, X-ray diffraction and microscop...
