Tantalum-containing cold spray coated ZK60 Mg alloys: Impact of surface treatments on morphology, wear, and corrosion resistance

Öz

Magnesium alloys, despite their lightweight properties, have not garnered the attention they deserve in the biomaterials sector due to their low wear and corrosion resistance. Alloys containing tantalum and coated materials are widely used in the implant industry and are frequently studied for their high corrosion resistance and antibacterial properties, making them suitable as biomaterials. In this study, tantalum-containing coatings were applied to the surfaces of ZK60 magnesium alloy, which had undergone various surface treatments, using the cold spray coating technique recently gaining traction in the literature due to its suitability for magnesium and its alloys under low-temperature conditions. The surface morphology, wear, and corrosion resistance of the coatings were evaluated, and the effects of surface treatments were discussed. The results indicated that the sample subjected to sandblasting before the coating process exhibited higher surface roughness, a thicker coating layer, and greater wear resistance compared to samples that underwent acid treatment and polishing. However, the increased roughness led to the accumulation of corrosion currents in localized areas, resulting in decreased corrosion resistance.

Tantal içerikli soğuk sprey kaplama uygulanan ZK60 Mg alaşımları: yüzey işlemlerinin morfoloji, aşınma ve korozyon dayanımına etkisi

Öz

Magnezyum alaşımları hafiflikleri ile ön plana çıkan fakat düşük aşınma ve korozyon dayanımları nedeni ile biyomalzeme sektöründe hak ettiği ilgiyi göremeyen bir alaşım grubudur. Tantal elementini içeren alaşımlar ve kaplanmış malzemeler implant sektöründe kullanılmakta ve gösterdikleri yüksek korozyon dayanımı ve antibakteriyel özellikler sebebi ile sıkça araştırılmakta ve biyomalzeme olarak kullanılmaktadır. Gerçekleştirilen çalışmada, altlık üzerinde düşük sıcaklık etkisi nedeni ile magnezyum ve alaşımları için kullanıma uygun bulunan ve literatürde yeni yer bulmaya başlayan soğuk sprey kaplama yöntemi ile, farklı yüzey işlemleri uygulanan ZK60 Mg alaşım yüzeylerine tantal içerikli kaplamalar gerçekleştirilmiştir. Kaplamaların yüzey morfolojileri, aşınma ve korozyon dayanımları değerlendirilmiş ve yüzey işlemlerinin etkileri tartışılmıştır. Çalışma sonucunda kaplama işlemi öncesi kumlama işlemi uygulanan numunenin, asitte bekletme ve parlatma işlemleri uygulanan numunelere göre daha yüksek yüzey pürüzlülüğüne, daha kalın kaplama tabakasına ve daha yüksek aşınma dayanımına sahip olduğu gözlemlenmiştir. Fakat yüksek yüzey pürüzlülüğü lokal bölgelerde birikerek buralarda korozyon akımının yoğunlaşmasına ve korozyon dayanımının düşmesine neden olmuştur.
