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

Abstract

N 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 analyzedby 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 highhardness and self-lubricating property
