The influence of Ti additions on the mechanical and electrochemical behavior of β-Ta5Si3 nanocrystalline coating


•β-(Ta0.9Ti0.1)5Si3 was calculated to be optimal composition to improve the ductility of β-Ta5Si3.•The addition of a certain amount of Ti has little impact on corrosion resistance of β-Ta5Si3.•Ti alloyed β-Ta5Si3 coating improve greatly corrosion resistance and hardness of Ti–6Al–4V.
