A RADIOCHEMICAL INVESTIGATION OF THE LEACHING OF CHROMIUM FROM CHEMICALLY CHROMATED ALUMINUM ALLOY SURFACES. PART III. THE 'UPTAKE' OF THE CHLORIDE ION INTO SUCH SURFACES,

Abstract

Radioactive tracer procedures are used to investigate the leaching characteristics of chromium dissolving from chromated aluminum surfaces to which an organic protective coating was applied during the aging process and which was removed prior to immersion in the salt solution. A radioactive tracer procedure is described to determine the chloride ion 'uptake' by chromated aluminum surfaces when immersed in salt solutions. Data are presented showing the effects of film thickness, aging periods and time of immersion in salt solution on the solution of chromium from the chromated surfaces and on the 'uptake' of chloride ions by these films.
