Manyetik Alanda Sıçratma Tekniğiyle Co-Cr-Mo Alaşımı Yüzeyinde Büyütülen TiN, NbN ve VN Kaplamasının, Yapısal ve Mekanik Özelliklerinin Araştırılması

Co-Cr-Mo alaşımları uzun yıllardan beri biyomedikal uygulamalarda kullanılmaktadır. Ancak malzemelerin vücut içerisinde hem tribolojik, hem de korozif ortamlara maruz kalması ve vücuda zararlı iyon salınımı gibi olumsuz özellikleri sebebiyle yüzey özelliklerinin geliştirilmesi önem arz etmektedir. Bu çalışmada fiziksel buhar biriktirme (PVD) manyetik alanda sıçratma tekniği kullanılarak Co-Cr-Mo alaşımı yüzeyine TiN-NbN ve VN esaslı biyouyumlu nitrür kaplama büyütüldü. Büyütülen kaplamanın yapısal ve morfolojik özellikleri XRD ve SEM analizi ile, kimyasal kompozisyonu EDS analizi ile gerçekleştirildi. Kaplama ve taban malzemenin korozyon davranışı potansiyodinamik polarizasyon testi ile %3.5'lik bir NaCl çözeltisiyle belirlendi. Son olarak çizilme testi ile kaplamanın yüzeye yapışma (adezyon) mukavemeti incelendi. Elde edilen veriler ışığında kaplamanın yüzeyde homojen bir dağılım gösterdiği görüldü. Korozyon testi sonucunda üretilen nitrür esaslı kaplama korozyon direncini yaklaşık olarak 2,5 kat arttırmıştır. Elde edilen kaplamanın korozyon sonrası SEM görüntüsü de korozyon hasarının önemli oranda engellendiğini göstermektedir. Kaplamanın çizilme testi sonuçları ise kaplamanın kritik yapışma mukavemeti değerinin yaklaşık 42 mN olduğunu göstermiştir. Daha düşük yükler ile yapılan testlerde sürtünme katsayısı ve sürtünme kuvvetinde önemli bir artış gözlemlenmemiştir. Bu veriler ışığında Co-Cr-Mo alaşımı yüzeyinde elde edilen TiN, NbN ve VN esaslı kaplama biyomedikal uygulamalarda kullanılabilecek uygun bir adaydır

Investigation of the Structural and Mechanical Properties of TiN, NbN, and VN Coating Deposition on the Co-Cr-Mo Alloy by Magnetron Sputtering

Co-Cr-Mo alloys have been used in biomedical applications for many years. However, it is important to improve the surface properties of materials due to their harmful properties, such as exposure to tribological and corrosive environments in the body and the release of toxic ions in the body. In this study, TiN-NbN and VN-based biocompatible nitride coating was grown on the Co-Cr-Mo alloy surface using the physical vapor deposition (PVD) magnetron sputtering. The structural and morphological properties of the grown coating were determined by SEM analysis, EDS, and XRD analysis. The corrosion behavior of the coating and substrate was determined by the potentiodynamic polarization test in a 3.5% NaCl solution. Finally, the adhesion strength of the coating to the surface was examined with the scratch test. In the light of the data obtained, it was seen that the coating showed a homogeneous distribution on the surface. The nitride-based coating produced as a result of the corrosion test increased the corrosion resistance approximately 2.5 times. The post-corrosion SEM image of the obtained coating also shows that corrosion damage is significantly prevented. The scratch test results of the coating showed that the critical bond strength value of the coating was approximately 42 mN. No significant increase in friction coefficient and friction force was observed in the tests performed with lower loads. In the light of these data, TiN, NbN, and VN-based coating obtained on the surface of Co-Cr-Mo alloy is a suitable candidate for biomedical applications.
