Mikro Ark Oksidasyon (MAO) Yöntemi ile Grade-2 Titanyum Alaşımı Üzerine Büyütülmüş Katkılı Oksit Kaplamaların Anti-Bakteriyel Duyarlılıklarının İncelenmesi

Abstract

Bu çalışma; biyomalzeme olarak kullanılabilen Cp-Ti (Grade-2) titanyum alaşımının yüzey özelliklerinin MAO yöntemiyle iyileştirilmesine ve anti bakteriyel duyarlılık kazandırılması üzerine odaklanmıştır. Gümüşün anti bakteriyel etkisinin MAO yöntemi ile kaplanmış Cp-Ti (Grade-2) titanyum taban malzemelere kazandırılması amaçlanmaktadır. Bu amaçla kaplamaların yapısal özellikleri SEM ve XRD cihazları kullanılarak analiz edilmiştir. Anti bakteriyel duyarlılıklarının ve bakteri adezyonunun incelenmesi için in vitro anti-bakteriyel etkinlik deneylerinde bakteriler kristal viyole kullanılarak işaretlenmiştir. Kaplamaların; adezyonu yüksek olan Staphylococous Aureus (S.aureus-ATCC 29213) bakterisine karşı duyarlılıkları araştırılmıştır. Çalışmada, gümüş içeren kaplamaların gümüş içermeyen kaplamalara göre bakteriyel duyarlılıklarının zayıf olduğu ve kaplama yapılmayan örneklerin ise bakteriye karşı oldukça duyarlı olduğu tespit edilmiştir.

The Investigation of Anti-Bacterial Susceptibilities of doped Oxide Coatings on Grade-2 Titanium Alloys Coated By Micro Arc Oksidasiyon (MAO) Process

Abstract

This work, Focuses on improving the surface properties of the Cp-Ti (Grade-2) titanium alloy, which can be used as biomaterial, with the MAO method and imparting anti-bacterial susceptibility. The antibacterial effect of silver is intended to be imparted to the Cp-Ti (Grade-2) titanium base materials coated with the MAO method. For this purpose, the structural properties of the coatings were analyzed using SEM, XRD and EDS instruments. In vitro antibacterial efficacy assays for bacterial susceptibility testing and bacterial adhesion were performed using bacterial crystal violet markers. The susceptibility of the coatings against to Staphylococous aureus (S.aureus-ATCC 29213) bacteria that has high adhesion was investigated. In the study, it was determined that the silver-containing coatings had a weaker bacterial susceptibility than the silver-free coatings and that the uncoated samples were more sensitive to bacterial contamination.
