  • An artifical pit technique has been used to study the anodic and cathodic behavior of Fe-Cr-Ni alloys during localized corrosion in neutral chloride solutions. The active dissolution kinetics have been determined as a function of the concentration of the localized environment, and the conditions for passivation established. Platinum microelectrodes have been used to analyze the pit solutions. The cathodic behavior of a pit on type 304L stainless steel is dominated by copper ions dissolved in the pit. A high purity Fe-Cr-Ni alloy behaves like stainless steel if copper is separately dissolved in the pit environment. The variation of dissolution ratemore » with concentration of corrosion products is used to show that localized corrosion can involve as many as five diffusion-coupled steady states. The stability of these states is discussed. 6 figures.« less
  • The dissolution kinetics of iron and cobalt have been measured under one-dimensional diffusional boundary conditions. Experimental results obtained in aggressive neutral electrolytes show features resulting from transient supersaturation, salt film precipitation and diffusion controlled dissolution. A mathematical model incorporating these features has been applied to metal dissolution in neutral chloride solutions. The effects of sulfur-containing ions on localized dissolution of iron are descirbed with reference to the stress-corrosion cracking of sensitized stainless steels. 12 figures.

  • Transient electrochemical measurements on film-free metal surfaces have often been used to test models of environment-assisted crack growth. The history of these attempts is reviewed, and the results are assessed in the light of what we now know about mechanisms of stress-corrosion cracking and corrosion fatigue. 98 references.
