چکیده

استفاده از نانوافزودنی­ها در روان­کننده­ها یکی از مؤثرترین روش­های کنترل اصطکاک و سایش است که برای حفظ انرژی، کاهش آلاینده­ها و حفاظت از محیط زیست از اهمیت بالایی برخوردار است. با رشد علم و فناوری، پیشرفت­های زیادی در زمینه افزودنی­های نانو­ روان­کار در تحقیقات علمی و کاربردهای صنعتی حاصل شده است. در این تحقیق به طور خلاصه به دسته بندی مواد افزودنی نانو­ روان­کار و بررسی خواص تریبولوژیکی این افزودنی­ها پرداخته شده است. بر اساس عناصر تشکیل دهنده نانو مواد، افزودنی­های نانو روان­کار برای سه گروه افزودنی­ها بر پایه نانو فلزات، افزودنی­ها بر پایه نانو کربن و افزودنی­ها بر پایه نانوکامپوزیت تشریح گردیدند. علاوه بر این انواع مکانیزم­های روان­کاری افزودنی­های نانو روان­کار شامل تشکیل تریبو فیلم، عملکرد خود ترمیم کننده و اثر هم افزایی نیز بیان شده است. درنهایت، چالش­ها و چشم انداز افزودنی­های نانو روان­کارها بیان شده است که طراحی و سنتز افزودنی های جدید با خاصیت روان کنندگی و ضدسایش در آینده را نشان می­دهد.
