... and metallographic evaluation in transverse sections, suggest strongly that the failure was caused by the operation of Type I pitting corrosion mechanism initiated from the inner side and propagated towards the outer tube surface, assisted by the flowing medium composition.

... polarization tests inferred that laser peening enabled shift of the pitting potential to more positive values, which ensures higher corrosion resistance. Originality/value Results confirmed that the higher corrosion resistance of the laser‐peened specimens against pitting corrosion depends...
