Abstract :
لايه نازك نيتريد تيتانيوم-مس با روش رسوب گذاري فيزيكي بخار توسط دستگاه لايه نشاني يوني مجهز به تفنگ تخليه الكتريكي كاتد توخالي در دماي زيرلايه C?350 بر روي زيرلايه استيل316 لايه نشاني شد. تاثير ميزان مس در بازه 7-2 د ر صد بر ساختار ريز ، مورفولوژي و خواص مكانيكي لايه نيتريد تيتانيوم–مس بررسي شد. جهت مشخصه يابي نمونه ها آناليز تفرق اشعه ايكس(XRD)، ميكروسكوپ الكتروني روبشي(SEM)، طيف سنجي تفرق انرژي اشعه ايكس (EDX) و ميكروسكوپ نيروي اتمي(AFM) مورد استفاده قرار گرفت. اندازه گيري نانوسختي و ضريب الاستيسيته به روش دندانه گذاري نانويي انجام شد. نتايج نشان مي دهند با افزودن فاز نرم مس به لايه NiT، سختي لايه هاي TiN ازGPa 30 به GPa 8/2 به سبب اثر روان كننده ذرات مس بين دانه هاي فاز سخت TiN كاهش مي يابد. نتايج آناليز تفرق اشعه ايكس نشان مي دهند كه فاز هاي مس و نيتريد تيتانيم به طور جداگانه رشد نموده و پيوند شيميايي بين اتم هاي مس و تيتانيم تشكيل نمي گردد.
Abstract :
Titanium nitride-Copper (TiN-Cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. The influence of Cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. Structural properties of the films were studied by X-ray diffraction pattern. Topography of the deposited films was studied using atomic force microscopy. Film hardness was estimated by a triboscope nanoindentation system. However, X-ray photoelectron spectroscopy analysis was performed to study the surface chemical bonding states. It was found that addition of soft Cu phase above 2 at.% to TiN film drastically decreased the film hardness from 30 to 2.8 Gpa due to lubricant effect of segregated copper particles. X-ray photoelectron spectroscopy results showed that Cu and TiN phases grew separately. In our case,the formation of a solid solution or chemical bonding between Cu and Ti was rejected.
