The process of magnesium ion modification of titanium surface and the sustained-release of magnesium ions from its surface.

This study explored modification of an alkaline heat treated titanium surface, using magnesium ions, to improve bone compatibility through the sustained release of magnesium ions. Pure titanium surface was first subjected to alkaline treatment using 5 M NaOH then modified with magnesium through immersion in magnesium chloride solution before heating in a furnace at 600°C for 1 h. Use of at least 0.
