THE CORROSION BEHAVIOUR OF ALUMINUM ALLOYS IN MARINE ATMOSPHERES

THIS PAPER DEALS WITH THE RESULTS OBTAINED BY ALUMINIUM LABORATORIES LIMITED IN ATMOSPHERIC CORROSION TESTS AT NUMEROUS MARINE SITES IN MANY PARTS OF THE WORLD. THE MATERIALS TESTED INCLUDED MOST OF THE ALUMINIUM ALLOYS AS WELL AS COPPER, LEAD, ZINC AND MILD STEEL. IT IS CONCLUDED THAT MOST ALUMINIUM ALLOYS HAVE AN EXCELLENT RESISTANCE TO CORROSION, EVEN IN VERY SEVERE MARINE ENVIRONMENTS. DISTANCE FROM THE SEA HAS LITTLE EFFECT EXCEPT WITH GALVANIC CORROSION WHERE THE EFFECT MAY BE CONSIDERABLE. IN SEVERE ENVIRONMENTS, CREVICES IN THIN MATERIALS SHOULD BE SEALED OR PAINTED. THE OTHER NON-FERROUS METALS SHOWED GOOD RESISTANCE, BUT AS JUDGED BY CORROSION RATES CALCULATED FROM WEIGHT LOSSES, THEY WERE INFERIOR TO ALUMINUM. /AUTHOR/
