Overview

Randomized trial evaluates corrosion behavior in friction-surfaced AA5083, suggesting microstructure plays a key role.

Key Points

  • To investigate how microstructure and residual stresses affect the electrochemical response of friction-surfaced AA5083.
  • Conducted immersion tests and cyclic polarization in chloride solutions at varying pH levels.
  • Monitored open circuit potential (OCP) to assess corrosion behavior.
  • Compared corrosion performance between substrate, deposited layer, and consumable stud materials.
  • The deposited layer demonstrated the highest pitting potential, indicating superior repassivation ability.
  • Immersion tests revealed significant pit nucleation across all conditions, with the deposited layer showing the highest density.
  • Corrosion response is influenced by the microstructure, residual stress, and passive film stability.
