ATMOSPHERIC CORROSION OF METALS AND ALLOYS AT THE MIRNYI STATION IN ANTARCTICA

Rates of atmospheric corrosion of St3, copper, cadmium, and D-16 alumi num alloy have been measured in a temperature climatic region of Antar ctica with very strong wind at the coastal station Mirnyi. Sulfate and chloride contents in soluble corrosion products were determined. Anal ysis of the results, taking into account climatic factors during the t est period, suggested the possibility of metal corrosion propagating i n a humid atmosphere at negative temperatures. These results are compa red with those of atmospheric tests of metallic materials in coastal a nd continental subarctic regions in the Far East.
