Research of Electrochemical Noise Technology on Corro-sion Resistance

摘要

This paper is focus on the corrosion resistance property analysis on three electric blasting of the coating—FeAl, FeCrAl, FeCrAIRE by electrochemical noise technology, acceleration of copper acetate salt spray accelerated corrosion test. According to a comparative analysis of three tests coated by the Impedance curve , FeCrAIRE coating power spectral density (SPD) curve and Power curve, FeAl, FeCrAIRE coating has two more notable for the corrosion resistance properties than FeAl, FeCrAl coatings.
