摘      要：The biodegradation behavior of Mg,coated by polymethyl methacrylate as well as polymethyl methacrylate(PMMA)−bioactive glass(BG)composite was *** deposition and dip coating techniques were adopted to prepare composite coating using a suspension of different percentages of the above two chemical *** deposited coatings were characterized using SEM,EDS,FTIR,and water contact angle *** behavior study of the coated Mg was performed using linear polarization,impedance spectroscopy,and immersion tests in simulated body *** compact and homogeneous composite coating was developed as evidenced by electron microscopy *** water contact angle measurement showed a 44°increase in the contact angle of the composite coated Mg compared to the uncoated *** composite coating was covered by a bone-like hydroxyapatite layer after 336 h,indicating that the coating has an excellent in vitro *** electrochemical testing results confirmed a significant reduction,96.9%,in the biodegradation rate of Mg coated with the composite prepared from 45 g/L PMMA+3.5 g/L 45S5 GB suspension compared to that of the uncoated ***,the composite coated Mg can be proposed as a promising material for biodegradable implant application.
