Investigation of processing effects on the corrosion resistance of Ti20Mo alloy in saline solutions

- Alloy fabrication method affects both surface finish and corrosion resistance.
- More porous surface finish and higher wettability produced by powder sintering.
- Passive layer formed on sintered alloy breaks down in saline solution.
- Increase in surface porosity facilitated electron transfer through the oxide film.
- More corrosion resistant alloy produced by cold crucible levitation melting.
