Development of Biodegradable Coating for Controlled Dissolution of a Magnesium Alloy as an Implant

Abstract:

In the present study, combinations of a Phosphonato silane DEPETES with MTEOS silane, in various ratios were applied on Mg6ZnCa alloy. The coating morphology was characterized using scanning electron microscopy (SEM) and hydrogen evolution and pH variation of the samples were studied. The results showed that the sol-gel coatings reduced the hydrogen evolution rate of the magnesium alloy in m-simulated body fluid (m-SBF) solution. Moreover, biological response like cell attachment on the coated sample was found to be enhanced considerably compared to the bare alloy
