Effect of argon ion sputter etching on the surface chemistry and surface properties of binary Ti-Nb alloys and commercially pure titanium
Original language description
The effect of argon ion sputter etching (Ar+) on Ti-Nb alloys with different niobium concentrations (Ti25Nb, Ti39Nb, and Ti55Nb) and distinct microstructures was investigated, using commercially pure titanium (CPTi) as a reference. The characterization included surface topography, surface morphology, chemistry, wettability, residual stress, and hardness to clarify the role of this process in the treatment of titanium materials for biomedical applications. Sputtering yields were additionally evaluated by Monte Carlo SDTrimSP simulations to complement the experiments. Etching exposed grain boundaries and generated intergranular height differences, with greater orientation diversity leading to increased surface roughness. The surface enrichment of niobium oxides after ion sputter etching rose with alloy niobium concentration and accordingly enhanced wettability. All Ti-Nb alloys exhibited a transition from hydrophobic to hydrophilic behavior. Moreover, ion sputter etching reduced residual stress, reflected by a decrease in surface hardness. Overall, the findings show that ion sputter etching, inherent to many PVD methods, has a decisive influence on the surface properties of Ti-Nb alloys and should be considered when designing surface treatments.
