چکیده

در این تحقیق با هدف کنترل خوردگی و امکان کاربرد کلینیکی منیزیم، پوشش دولایه هیدروکسی ‏آپاتیت -پلی ‏لاکتیک‏ گلیکو لیک ‏اسید به ترتیب با روش‌های رسوب دهی الکتریکی و غوطه وری بر نمونه منیزیمی اعمال گردید. مشخصه ‏یابی پوشش‌ها با کمک پراش پرتو ایکس و میکروسکوپ الکترونی روبشی، نشان دهنده تشکیل یکنواخت پوشش ها با ضخامت µm 30 – 20 بر سطح منیزیم است. آزمون‏ الکتروشیمیایی پلاریزاسیون تافل بر نمونه‌ها نشان داد که با اعمال پوشش دو لایه هیدروکسی ‏آپاتیت- پلی ‏لاکتیک ‏گلایکولیک ‏اسید بر منیزیم، پتانسیل خوردگی از V 82/1- به V 4/1- افزایش و چگالی جریان خوردگی از µA/cm2 3/2 به µA/cm2 37/0 کاهش می‏ یابد. نتایج آزمون MTT نیز نشان داد که مقدار تکثیر سلولی در مجاورت عصاره 48 ساعته نمونه‏ های منیزیمی با پوشش دو لایه بیشتر شده است، که حکایت از کاهش مقدار یون آزاد شده از سطح منیزیم با کمک اعمال این پوشش ها است.

چکیده [English]

In this study, intending to control the corrosion of magnesium and its clinical application, a double-layer coating of Hydroxyapatite- Poly lactic-co-glycolic acid was applied on Mg by means of the electrodeposition and the dip method, respectively. X-ray diffraction (XRD) and scanning electron microscopy (SEM) are used to characterize the phase and morphology of the coatings. The results show a homogeneous coating with a thickness of 20-30 µm. Potentiodynamic polarization of the samples revealed that the double-layer coating exhibited a significant increase in corrosion potential, ranging from -1.82 to -1.4 V, and a decrease in corrosion current, ranging from 2.3 to 0.37 µA/cm2. Moreover, the MTT assay of the samples revealed that the amount of cell proliferation in the vicinity of the 48-hour extract of magnesium samples with double-layer coating had increased, indicating a decrease in the amount of ions released from the surface of magnesium by applying this coating.
