摘 要：A uniform,compact,and well adherent conversion coating of magnesium hydroxide has been formed on bioresorbable magnesium disks by means of a hydrothermal technique Electrochemical results indicate that the coating brings about a significant reduction in magnesium corrosion in phosphate buffered saline(PBS)solution.It is also observed that corrosion resistance of the coating increases with an increase in treatment time,which in turn,increases the coating thickness.The protective behavior of magnesium hydroxide coating is attributed to its chemical inertness in PBS solution.The coatings are found to be free from pores that reduce the direct contact between corroding media and underlying magnesium.
