Ni, Ni-B ve Ni-B/hBN kaplamaların elektrodepolanmasında banyo bileşenlerinin kaplama özelliklerine etkisinin incelenmesi

Bu çalışmada, saf nikel, Ni-B alaşım ve Ni-B/hBN kompozit kaplamalar elektrodepolama yoluyla üretilmiştir. Bu kaplamaları elde etmek için banyoya eklenen bileşenlerin miktarları sabit tutulmuş ve her birinin ayrı ayrı kaplama üzerine etkileri araştırılmıştır. Üretilen kaplamaların kristal yapıları XRD ile, yüzey morfolojileri ve kimyasal içerik analizleri SEM ve EDS ile, elektrokimyasal davranışları ise dönüşümlü voltametri (CV) ile incelenmiştir. Ayrıca kaplamaların korozyon dayanımları % 3.5 NaCl içeren çözelti içerisinde açık devre potansiyeli ve Tafel ekstrapolasyon metotlarıyla belirlenmiştir. Elde edilen sonuçlara göre ince taneli, düzgün yüzeyli ve kompakt kaplamalar üretilmiştir. Banyoya eklenen bileşenler kristal yapıyı, korozyon dayanımını ve diğer özellikleri ciddi derecede etkilemektedir.
