Abstract

Pure titanium has a very large potential for use industrially due to its low weight, however, its usage continues to be limited because it possesses some disadvantages such as low hardness and wear resistance, weak corrosion resistance in high temperatures and high cost. In order to strengthen these weaknesses of pure titanium, electroless Ni-B deposition process, may be an alternative solution. In this study, the Ni-B coatings were deposited on pure titanium and annealed at the temperatures of 450°C, 650°C and 850°C. The non-heat treated and heat treated coatings were structurally characterized via SEM (scanning electron microscope) and XRD (x ray diffraction). These coatings transformed from amorphous structure to a pronounced crystalline structure depending on heat treatment.

Özet

Saf titanyum, düşük ağırlığı nedeniyle sanayide çok geniş kullanım potansiyeline sahiptir, fakat diğer taraftan düşük sertlik ve aşınma direnci, yüksek sıcaklıklarda zayıf korozyon direnci ve yüksek maliyet gibi taşıdığı bazı dezavantajlar nedeniyle kullanımı hala sınırlı olmaya devam etmektedir. Saf titanyumun bu zayıf yanlarını güçlendirmek amacıyla akımsız Ni-B kaplama alternatif çözümlerden biri olabilir. Bu çalışmada, saf titanyum üzerine akımsız kaplama yöntemi ile Ni-B kaplamalar yapılmış ve 450°C, 650°C ve 850°C sıcaklıklarda ısıl işlem uygulanmıştır. Isıl işlem uygulanmayan ve uygulanan bu kaplamalar, yapısal olarak SEM (taramalı elektron mikroskop) ve XRD (X ışını kırınım ölçer) ile karakterize edilmiştir. Kaplamaların ısıl işleme bağlı olarak amorf karakterden belirgin kristalin bir yapıya dönüştüğü gözlenmiştir.
