Hydrogen Absorption Into Alpha Titanium Alloys

Abstract

Hydrogen absorption into titanium alloys during crevice corrosion has been studied in 0.27 mol/cm³ at 95°C. Experiments of different durations were performed to investigate the progression of crevice corrosion and hydrogen absorption. It was found that the main driving force for crevice corrosion processes was proton reduction inside the crevice rather than O₂ reduction on the counter electrode. The data also showed that the amount of absorbed hydrogen and the maximum penetration depth increased with time.
