Abstract

Commercially pure titanium (CP Ti) has gained significant attention for biomedical applications due to its favorable strength-to-weight ratio and excellent biocompatibility. Nonetheless, its inherent corrosion resistance remains insufficient for certain functional environments, necessitating surface modifications to enhance its durability. In this context, the present study focused on improving the tribological and surface characteristics of CP Ti by depositing chromium carbonitride (CrCN) films via physical vapor deposition (PVD). The morphological and structural differences between uncoated and coated specimens were analyzed through X-ray diffraction (XRD) and scanning electron microscopy (SEM). Furthermore, a comparative assessment of wear performance was conducted using a pin-on-disk tribometer. The findings revealed that the CrCN-coated samples demonstrated superior wear resistance, which was attributed to their increased surface hardness and reduced roughness compared to the uncoated specimens.

Özet

Ticari olarak saf titanyum (CP Ti), uygun mukavemet-ağırlık oranı ve mükemmel biyouyumluluğu nedeniyle biyomedikal uygulamalarda büyük ilgi görmektedir. Bununla birlikte, doğal korozyon direnci belirli fonksiyonel ortamlar için yetersiz kalmakta ve dayanıklılığını artırmak için yüzey modifikasyonları gerekmektedir. Bu bağlamda, mevcut çalışma, fiziksel buhar biriktirme (PVD) yoluyla krom karbonitrür (CrCN) filmleri biriktirerek CP Ti'nin tribolojik ve yüzey özelliklerini iyileştirmeye odaklanmıştır. Kaplanmamış ve kaplanmış numuneler arasındaki morfolojik ve yapısal farklılıklar, X-ışını difraksiyonu (XRD) ve taramalı elektron mikroskobu (SEM) ile analiz edilmiştir. Ayrıca, pin-on-disk tribometre kullanılarak aşınma performansı karşılaştırmalı bir değerlendirme yapılmıştır. Bulgular, CrCN kaplı numunelerin, kaplanmamış numunelere kıyasla artan yüzey sertliği ve azalan pürüzlülüğü sayesinde üstün aşınma direnci gösterdiğini ortaya koymuştur.
