CORROSION RESEARCH ROUND‐UP

Abstract

U.S.A. Autoclave testing of zirconium alloys. No significant difference between water corrosion of American and British Zircaloy 2 at 320°C. is observed when corrections for variations in autoclave testing techniques are made. Nitrogen contents up to 220 p.p.m. can be tolerated in British Zircaloy without acceleration of attack. Mechanical polishing of the conventional nitric‐hydrofluoric acid pickle, as pre‐treatments prior to testing, appear to be equally efficient in minimising corrosion effects. Welding does not impair corrosion resistance, provided the weld is ‘bright’ as made and surface polished.
