| چکیده | ||
| در این پژوهش، تأثیر نانو ذرات زئولیت بر خواص سایشی پلی اتیلن با وزن مولکولی بسیار بالا که کاربرد فراوانی در کاشتنی‌های ارتوپدی دارند، مورد مطالعه قرار گرفته است. بهبود خواص سایشی این پلیمر، از جمله چالش‌های صنعت پزشکی می‌باشد و تأثیر مستقیم بر عمر کاشتنی‌های ارتوپدی دارد. نمونه‌های استوانه‌ای نانوکامپوزیتی بر پایه آمیخته پلی اتیلن با وزن مولکولی بسیار بالا حاوی نانوذرات زئولیت (2، 4 و 6 درصد وزنی) به روش اکسترودر و قالب‌گیری تزریقی تولید شد. شکل شناسی نمونه‌ها با میکروسکوپ الکترونی روبشی مطالعه شد. با استفاده از آزمون پین روی دیسک، مقدار سایش، دما و ضریب اصطکاک تحت نیروی فشاری N 50 و سرعت ثابتm/s 5/0 اندازه‌گیری شد. مقدار سایش، دما و ضریب اصطکاک در نمونه حاوی 4 درصد وزنی از نانو زئولیت، پس از 4500 متر، به‌ترتیب حدود 56، 32 و 26 درصد کمتر از نمونه پلی اتیلنی خالص مشاهده شد. در مقابل، بکارگیری 6 درصد وزنی از نانو ذرات زئولیت، منجر به کلوخه شدن ذرات و افزایش مقدار سایش، دما و ضریب اصطکاک، نسبت به نمونه‌های نانوکامپوزیتی شد. علاوه‌براین، مورفولوژی نمونه‌های نانوکامپوزیتی، پس از آزمون، سطح صافتر و با آثار سایش خراشی کم عمق‌تر نسبت به سطح ساییده شده نمونه پلی اتیلنی خالص نشان داد. | ||

| چکیده [English] | ||
| In this research article, the effect of zeolite nanoparticles on the tribological properties of ultra-high molecular weight polyethylene, which are widely used in orthopedic implants, and its nanocomposites have been studied. Improving the tribological properties of this polymer is one of the medical industry challenges which has an important effect on the lifetime of orthopedic implants. Nanocomposites based on ultra-high molecular weight polyethylene blend, containing 2 to 6 wt. % of nano-zeolite were prepared via melt compounding followed by injection molding. The morphology was studied using scanning electron microscopy. The wear rate and contact temperature of specimens, as well as friction coefficient, were characterized by employing a pin on disk wear test under 50 N and sliding velocity of 0.5 m/s. The wear rates, contact temperature, and friction coefficient of nanocomposite containing 4 wt. % of nano-zeolite, were 56, 32, and 26%, respectively, lower than those of neat ultra-high molecular weight polyethylene. In contrast, the application of 6 wt. % of nano-zeolite led to agglomeration and increased wear, temperature, and coefficient of friction compared to nanocomposite samples. In addition, the morphology of nanocomposite samples, after testing, revealed a smoother surface with mild abrasion marks than that of pure ultra-high molecular weight polyethylene sample. | ||
