Improvement of Surface Properties via an Electroless Ni-B Coating for Commercial Purity Titanium

Abstract

In the present study, the surface of commercial pure titanium (CP-Ti) was coated with electroless Ni–B. The surface morphology, microstructure and phase identification were analyzed by Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD). The obtained Ni-B coating demonstrated significantly lower wear rate and stable friction coefficient compared to bare CP-Ti. The superior wear resistance of Ni-B coating on the CP-Ti is dealt with the combination of its high hardness and self-lubricating property.

Ticari Saflıkta Titanyumun Akımsız Ni-B Kaplaması ile Yüzey Özelliklerinin Geliştirilmesi

Abstract

Bu çalışmada, ticari saf titanyumun (CP-Ti) yüzeyi akımsız Ni-B ile kaplandı. Yüzey morfolojisi, mikroyapı ve faz analizi, Taramalı Elektron Mikroskobu (SEM) ve X-Işınları Difraksiyonu (XRD) ile analiz edildi. Elde edilen Ni-B kaplama, işlem görmemiş CP-Ti'ye kıyasla önemli ölçüde daha düşük aşınma hızı ve kararlı sürtünme katsayısı sergilemiştir. CP-Ti yüzeyine oluşturulan Ni-B kaplamanın üstün aşınma direnci sergilemesi, oluşturulan kaplamanın yüksek sertlik ve kendinden yağlama özelliğinden kaynaklanmaktadır.
