Abstract:

 In this study, Ni-PZrO2 nanocomposite coatings were deposited on St-37 steel substrates using the electroplating method with varying ZrO2 concentrations 10 gL ve 20 gL and current densities 50 mAcm2 ve 75 mAcm2. To investigate the effects of electrolyte components and current density on coating properties, analyses were performed regarding microhardness, wear performance, and surface morphology. As a result of the analyses, it is observed that different bath concentrations and current densities significantly affect properties such as morphology, hardness, and wear performance. It is seen that the surface morphologies of the obtained coatings are generally smooth, but it is understood from the optical images that the surfaces of all nanocomposite coatings are rougher. While adding ZrO2 nanoparticles to the main matrix increases microhardness by approximately 40 compared to pure nickel, a similar but higher hardness value was obtained with the increase in current density. When examined in terms of wear performance, an average friction coefficient value of 3.15 times higher than that of pure nickel nanocomposite coatings was obtained.

 Bu çalışmada, Ni-PZrO2 nanokompozit kaplamalar, değişen ZrO2 konsantrasyonları 10 gL ve 20 gL ve akım yoğunlukları 50 mAcm2 ve 75 mAcm2 ile elektrokaplama yöntemi kullanılarak St-37 çelik alt tabakalar üzerine biriktirildi. Elektrolit bileşenlerinin ve akım yoğunluğunun kaplama özelliklerine etkilerini incelemek amacıyla mikrosertlik, aşınma performansı ve yüzey morfolojileri açısından analizler yapılmıştır. Yapılan analizler sonucunda farklı banyo konsantrasyonun ve akım yoğunluğunun morfoloji, sertlik ve aşınma performansı gibi özellikleri ciddi miktarda etkilediği görülmektedir. Elde edilen kaplamaların genel olarak yüzey morfolojiler pürüzsüz olduğu görülmektedir ama nanokompozit kaplamaların hepsinde yüzeyinin daha pürüzlü olduğu optik resimlerden anlaşılmaktadır. Ana matrise eklenen ZrO2 nanopartikülü ilavesi mikro sertliği saf nikele göre yaklaşık 40 oranında artırırken, akım yoğunluğunun artmasıyla beraber yakın ama daha yüksek sertlik değeri elde edilmiştir. Aşınma performansı bakımından incelendiğinde, saf nikel nanokompozit kaplamalara göre 3.15 kat daha fazla ortalama sürtünme katsayısı değeri elde edilmiştir.
