Bu çalışmada endüstriyel olarak sıklıkla kullanılan 304L kalite çelik altlıklar üzerine, üstün katı yağlayıcılıkve mekanik mukavemet özellikleri gösteren hegzagonal bor nitrür (hBN) nano partikülleriyledesteklenmiş nikel-bor (Nİ-B) alaşım matrisli kompozit kaplamalar galvanostatik elektrodepolamayoluyla kaplanmıştır. Çalışmada Tergitol™ yüzey aktif madde (sürfaktan) olarak kullanılmış ve bu yüzeyaktif maddenin depolama süspansiyonundaki konsantrasyonunun kaplamaların yapısal, morfolojik,mikrosertlik, ve korozyon koruma özellikleri üzerine etkisi sırasıyla XRD, FE-SEM, Vickers mikrosertlik,potansiyodinamik polarizasyon ve elektrokimyasal empedans spektroskopisi kullanılarak incelenmiştir.Sonuç olarak, Tergitol'ün metal matrisli kompozit kaplamaların elektrodepolanması için etkili bir yüzeyaktif madde olarak kullanılabileceği sonucuna varılmıştır.

Effect of the Tergitol Concentration on the Electrodepositon of Ni- B/hBN composite Coatings

In this study, hexagonal boron nitride (hBN) nanoparticles which has superior solid lubrication and mechanical strength properties reinforced nickel-boron (Ni-B) alloy matrix composite coatings were fabricated by galvanostatic electrodeposition on 304 L grade steel widely used in the industry. In the study, Tergitol ™ was used as a surfactant. The effect of the surfactant concentration on the structural, morphological, microhardness, and corrosion protection properties of the coatings was investigated using XRD, FE-SEM, Vickers microhardness, potentiodynamic polarization, and electrochemical impedance spectroscopy, respectively. It was concluded that Tergitol™ can be used as an effective surfactant for electrodeposition of metal matrix composite coatings.
