اگرچه مواد فلزی مختلفی برای ترمیم و جایگزینی در بدن موجود زنده در دسترس است ولی به دلیل نگرانی از خوردگی فلز و آزاد شدن یون ها و پیامدهای احتمالی آن فقط تعداد محدودی از آلیاژها جهت تهیه ایمپلنت های بدن کاربرد کلینیکی یافته اند و تلاش برای بهبود رفتار خوردگی و زیست-سازگاری فلزات جهت استفاده در بدن ادامه یافته است. در پژوهش حاضر کوشش شد تا برای دستیابی همزمان به دو هدف؛ بهبود مقاومت خوردگی ایمپلن...

In order to further enhance tribological properties 316 Low carbon stainless steel (L SS) used on mechanical parts. CrN/TiN with DC magnetron sputtering sources was carried out on PVD 316 L SS. The micro structure of the CrN/TiN coatings were investigated by Scanning electron microscope (SEM), X-ray Diffraction (XRD) and tribology properties were investigated on a Pin on Disc friction and wear ...
PURPOSE The objective of this systematic review was to summarise the outcome after cast wedging due to loss of angulation in conservative fracture treatment of children's fractures. METHODS Electronic searches were performed using MEDLINE, PubMed, OVID, CENTRAL and EMBASE without language restrictions. RESULTS Three studies comprising 316 patients (210 radius, 52 forearm/both bone forearm f...
