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.
