Özet:

 Titanium implants are mechanical systems where tribocorrosion is frequently observed at the interface between the implant and the abutment alloy. In this paper, important parameters in terms of tribocorrosion such as abrasion coefficient, abrasion volume loss and corrosion rate were determined experimentally in a laboratory environment by preparing a sufficient number of samples obtained from the field for this material Titanium-Ti6Al4V, which is actively used in surgeries. Comprehensive analysis of these mechanical systems in body-like environments contributes to a better understanding of the material loss caused by abrasion and corrosion interactions occurring at the interface between the implant and the abutment alloy. The samples were subjected to dry sliding wear with the pin-on-disc system in accordance with the relevant standards for a certain number of cycles, during which abrasion volume loss and friction coefficient were measured simultaneously. The results of these experiments were examined to evaluate the degree to which titanium is resistant to material loss due to abrasion and corrosion in body implants. It was found that the abrasion coefficient decreased by 51 when 10 N load was applied by 22 when 20 N load was applied, and by 2 when 30 N load was applied. The samples screws were exposed to 15 more corrosive abrasion and it was found that they had 6 higher corrosion rate in electrochemical corrosion test. Additionally, the morphological features of the abraided and corroded surfaces of Ti6Al4V alloy were analyzed and interpreted using scanning electron microscopy SEM and digital image processing techniques.

 Titanyum implantlar, implant ile abutment alaşımı arasındaki arayüzde tribokorozyonun sıklıkla görüldüğü mekanik sistemlerdir. Bu çalışmada, cerrahide aktif olarak kullanılan bu malzeme Titanyum-Ti6Al4V için sahadan elde edilen yeterli sayıda numune hazırlanarak, aşınma katsayısı, aşınma hacim kaybı ve korozyon hızı gibi tribokorozyon açısından önemli parametreler laboratuvar ortamında deneysel olarak belirlenmiştir. Bu mekanik sistemlerin vücut benzeri ortamlarda kapsamlı analizi, implant ile abutment alaşımı arasındaki arayüzde oluşan aşınma ve korozyon etkileşimlerinin neden olduğu malzeme kaybının daha iyi anlaşılmasına katkıda bulunmaktadır. Numuneler, ilgili standartlara uygun olarak belirli sayıda çevrim boyunca pim-disk sistemi ile kuru kayma aşınmasına tabi tutulmuş ve bu esnada aşınma hacim kaybı ve sürtünme katsayısı eş zamanlı olarak ölçülmüştür. Bu deneylerin sonuçları, titanyumun vücut implantlarında aşınma ve korozyona bağlı malzeme kaybına karşı ne kadar dirençli olduğunu değerlendirmek için incelenmiştir. Aşınma katsayısının 10 N yük uygulandığında 51, 20 N yük uygulandığında 22 ve 30 N yük uygulandığında 2 azaldığı tespit edilmiştir. Numune vidalar 15 daha fazla korozif aşınmaya maruz kalmış ve elektrokimyasal korozyon testinde 6 daha yüksek korozyon oranına sahip oldukları tespit edilmiştir. Ek olarak, Ti6Al4V alaşımının aşınmış ve korozyona uğramış yüzeylerinin morfolojik özellikleri, taramalı elektron mikroskobu SEM ve dijital görüntü işleme teknikleri kullanılarak analiz edilmiş ve yorumlanmıştır.
