Özet:

 In this study, TiN films were coated on the surface by cathodic arc physical vapor deposition CAPVD method in order to improve the corrosion resistance and hydrophobic properties of 316L stainless steel, which is used as a biomaterial. The surface morphology, surface composition, corrosion resistance, and wettability of the coated samples were characterized and the characterization of the coatings was done by XRD, SEM and EDS. After electrochemical experiments in simulated body fluid  SBF solution, it was observed that the corrosion resistance of the coating film increased. In addition, contact angle measurements were taken with distilled water, n-hexadecane, ethylene glycol, and SBF solutions to determine the wettability and free surface energy properties of untreated and coated samples. The hydrophobic and oleophobic properties of the surfaces were obtained after the coating film, and the contact angle value increased from 92 to 119 after the contact angle measurement with the SBF solution. According to the measured contact angle values, the surface free energy values of the untreated and TiN coated stainless steel samples were calculated as 26.7 mNm and 18.5 mNm, respectively, according to the measured contact angle values.

 Bu çalışmada, biyomalzeme olarak kullanılan 316L paslanmaz çeliğin korozyon direnci ve hidrofobik özelliklerinin iyileştirilmesi amacıyla TiN filmler katodik ark fiziksel buhar biriktirme CAPVD yöntemi ile yüzeye kaplanmıştır. Kaplanmış numunelerin yüzey morfolojisi, yüzey bileşimi, korozyon direnci ve ıslanabilirliği karakterize edilmiş ve kaplamaların karakterizasyonu XRD, SEM ve EDS ile yapılmıştır. Yapay vücut sıvısı SBF çözeltisinde yapılan elektrokimyasal deneyler sonrasında kaplama filminin korozyon direncini artırdığı görülmüştür. Ayrıca, işlemsiz ve kaplanmış numunelerin ıslanabilirlik ve serbest yüzey enerjisi özelliklerinin belirlenmesinde saf su, hekzadekan, etilen glikol ve SBF çözeltileri ile temas açıları ölçümleri alınmıştır. Yüzeylerin kaplama filmi sonrasında hidrofobik ve oleofobik özellikleri elde edilmiş olup, SBF çözeltisi ile yapılan temas açısı ölçüm sonrasında temas açısı değeri 92den 119ye kadar artmıştır. İşlemsiz ve TiN kaplanmış paslanmaz çelik numunelerin serbest yüzey enerjisi değerleri ölçülen temas açısı değerlerine göre sırasıyla 26.7 mNm ve 18.5 mNm olarak hesaplanmıştır.
