Akımsız Kaplama Yöntemi ile Üretilmiş Grafen Takviyeli Gümüş Matrisli Nanokompozitlerin Yapısal Özellikline Banyo Bileşiminin Etkisi

Bu çalışmada akımsız kaplama yöntemi ile bakır altlıklar üzerine Gümüş (Ag) ve Grafen (Gr) takviyeli Ag matrisli nanokompozit kaplanmıştır. Ag kaplama banyoları içerisine farklı oranlarda Gr ilave edilerek Gr oranının mikro yapı ve mekanik özelliklere etkileri incelenmiştir. Ag ve Ag-Gr nanokompozit kapamaların yapısal özelikleri taramalı elektron mikroskobu (SEM), Elektron dağılımlı X-ışınları spektrometresi (EDS), Raman ve X ışınları dağılım spektrometresi (XRD) yardımı ile mekanik özellikleri ise mikrosertlik yöntemi kullanılarak incelenmiştir. Kaplama banyosuna Gr ilavesi belirgin bir şekilde matris mikroyapısını değiştirmiş ve yüzey sertliğini artırmıştır. En yüksek sertlik değeri banyo bileşimine 0.5 g/l Gr ilavesi ile elde edilmiştir.

Effect of Bath Composition on Structural Properties of Graphene Reinforcement Silver Matrix produced by Electroless Deposition

In this study, Silver (Ag) and Graphene (Gr) reinforcement Ag matrix nanocomposite coated on copper substrate by electroless coating method. Different amount of Gr was added to Ag electroless coating electrolyte and effect of Gr amount on microstructure and mechanical properties were investigated. Ag and Ag-Gr nanocomposites structural properties characterized with Scanning Electron Microscope (SEM), Energy-dispersive X-ray spectroscopy (EDS), Raman and X-ray Diffractions (XRD). Mechanical properties were measured with microhardness method. Gr addition to electrolyte was strongly affected matris microstructure and increased hardness value. Highest hardness value was achieved with 0.5 g/l Gr addition to electrolyte.
