THE SEASONAL DISTRIBUTION OF FERROUS SULPHATE FORMED DURING THE ATMOSPHERIC RUSTING OF MILD STEEL

ELECTRON PROBE MICRO-ANALYSIS WAS APPLIED TO SPECIMENS OF RUST FORMED BY THE ATMOSPHERIC CORROSION OF MILD STEEL SHEETS EXPOSED DURING FEBRUARY, 1964, IN MANCHESTER, ENGLAND. THE SLIGHT CORROSION EXPERIENCED DURING THE SUCCEEDING FOUR MONTHS WAS FOUND TO RESULT IN ONLY A SLIGHT FIXATION OF SULPHUR. CONTINUED EXPOSURE DURING THE NEXT EIGHT MONTHS COINCIDED WITH A MARKED INCREASE IN SULPHUR- CONTAINING FORMATIONS, PREDOMINANTLY IN THE FORM OF BANDS AT THE METAL-RUST INTERFACE. FURTHER EXPOSURE FOR FOUR MONTHS PERMITTED THE SULPHUR-CONTAINING BANDS FOUND PREVIOUSLY TO MOVE OUTWARDS THROUGH THE RUST TO FORM NESTS. SPECIMENS EXPOSED INDEPENDENTLY AT LONDON AND CAMBRIDGE ALSO REVEALED SULPHUR-CONTAINING INCLUSIONS AT THE INTERFACE BETWEEN STEEL AND RUST. /AUTHOR/
