Abstract

Akımlı ve akımsız nikel kaplamalar, sahip oldukları korozyon direnci ve fonksiyonel özellikleriyle birçok endüstriyel alanda yaygın olarak kullanılmaktadır. Bu bağlamda, nikel-bor (Ni-B) alaşım kaplamaları, sert krom (Cr) kaplamalara çevresel ve teknik açıdan alternatif olabilecek önemli bir potansiyel sunmaktadır. Bu çalışmada, elektrodepozisyon yöntemiyle farklı akım yoğunluklarında elde edilen Ni-B kaplamaların mikroyapı, yüzey morfolojisi, sertlik, aşınma davranışı ve kristal yapı özellikleri detaylı şekilde incelenmiştir. Karakterizasyon çalışmaları kapsamında SEM, mikroyüzey sertliği ve aşınma testleri uygulanmıştır. Elde edilen sonuçlar, Ni-B kaplamaların yüksek sertlik ve aşınma direnci sunduğunu, aynı zamanda sert krom kaplamalara çevre dostu bir alternatif olabileceğini göstermektedir.

ELECTRODEPOSITED NI–B COATINGS PRODUCED AT DIFFERENT CURRENT DENSITIES: VIABILITY AS AN ALTERNATIVE TO HARD CHROMIUM

Abstract

Electrolytic and electroless nickel coatings are widely used in various industrial applications due to their corrosion resistance and functional properties. In this context, nickel-boron (Ni-B) alloy coatings offer significant potential as an environmentally and technically viable alternative to hard chromium (Cr) coatings. In this study, the microstructure, surface morphology, hardness, wear behavior, and crystal structure of Ni-B coatings produced by electrodeposition at different current densities were investigated in detail. Characterization studies included SEM analysis, microhardness measurements, and wear tests. The results demonstrated that Ni-B coatings exhibit high hardness and wear resistance, indicating their potential as an environmentally friendly substitute for hard chromium coatings.
