Abstract:

Studies were made with an artificial pit in the side of a flow channel to obtain quantitative data on hydrodynamic effects on pitting rate. Experiments were conducted under potentiostatic conditions with titanium, aluminum and iron in chloride, bromide and iodide solutions. Two modes of pitting were observed a high current density limited only by ohmic resistance in solution and a lower current density limited by mass transport of some species. The mass transport limited mode was observed in addition to the ohmic mode for titanium in bromide and iodide and for iron in chloride solution.
