Measurement of the critical pitting potential of aluminium

摘要: Abstract The electrochemical methods for the measurement of critical pitting potential have been analyzed in terms their applicability to aluminium and its alloys. Interpretation data these alloys may follow different guidelines than those developed more noble like steel order obtain meaningful results. Present work a literature survey show that most give fairly accurate results with careful analysis exception fast-scan methods. Experimental difficulties associated are reviewed. varies appreciably chloride concentration, other factors such as surface treatment, temperature, small additions alloying elements being minor importance. significance is discussed view this result.
