Abstract

Abstract

Effect of physical parameters(scratching time and scratching velocity) during the scratching process on the maxium reaction current of bare surface has been discussed in detail. Analysis results indicate that the maxium reaction current of bare surface varies as the scratching time or velocity changes.This kind of variation would make the decay parameter of repassivation kinetics distort.So the traditional scratch method is not able to investigate quantitalively the repassivation process of metals.
