The aim of this study is to prepare sphene coating on titanium alloy (Ti-6Al-4V) for orthopaedic applications using the plasma spray method. The results indicated that sphene coating was obtained with a uniform and dense microstructure.

Plasma-sprayed sphene coating possessed a significantly improved bonding strength and chemical stability compared with that plasma-sprayed hydroxyapatite (HAp) coating.

Plasma-sprayed sphene coating supported human osteoblastic-like cells (HOB) attachment and significantly enhanced HOB proliferation and differentiation compared to plasma-sprayed HAp coating.

Taken Plasma-sprayed sphene coating possessed excellent bonding strength, chemical stability and cellular bioactivity, indicating its potential application for orthopaedic implants.
