Abstract
The corrosion rates of titanium in 1-4 M H2SO4 at temperatures of 298, 313 and 333 K were measured. It was found that etching in 5% HF stron gly decreases the time for the passive-active transition (self-activat ion) of titanium in H2SO4 and it was therefore used as an initial pret reatment for all samples. The steady state corrosion rates of titanium in H2SO4 increased linearly with the cube of the molar concentration.
