Characterisation of bioactive films on Ti–6Al–4V alloy

Electrochimica Acta, 2013
Abstract In an attempt to increase the bioactivity and corrosion resistance of a Ti–6Al–4V alloy, the plasma electrolytic oxidation (PEO) process for surface modification was utilised. Selected samples were subjected to further treatment, either thermal or alkali. The morphology, chemical composition and phase composition of the ground and treated Ti–

Effect of fast-frequency pulsed waveforms on the microstructure and mechanical properties of Ti–6Al–4V alloy welded by FFP-TIG

Journal of Materials Research and Technology, 2022
Ti–6Al–4V alloys have been widely adopted because of their good mechanical properties. TIG welding is a common method for Ti–6Al–4V alloys. However, the high heat input of conventional TIG can lead to a coarsening of grains within Ti–6Al–4V and thus a ...

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.
