Magnesium Alloy cardiovascular stent with the micro-arc oxidation coating

摘要

1)The micro-arc oxidation coatings have porous micro structures and some volcano top-like pores distribute disorderly on the coating surface.2)From XRD it can be concluded that the main phase composition of Micro-arc oxidation coating was consists of MgAl_2O_ 4 and MgSiO_3.3)The corrosion resistance of the Micro-arc oxidation coatings was obviously prior to the untreated.
