Effect Of Inhibitor On Electrochemical Behavior Of 1cr18 Stainless Steel In Acidic Solution Under Friction, Jinping Xiong
Effect Of Inhibitor On Electrochemical Behavior Of 1cr18 Stainless Steel In Acidic Solution Under Friction, Jinping Xiong
Journal of Electrochemistry
The electrochemical behavior of 1Cr18 stainless steel had been studied using a reciprocating triboelectrochemical equipment under friction in 0.2 mol/L H2SO4 solution with and without addition of thiourea, the frictionized surface of 1Cr18 stainless steel had been examined by the SEM, XPS and IR. The results showed that the loss rate of 1Cr18 stainless steel in the solution could be reduced by addition of thiourea. The adsorption of thiourea on the surface of 1Cr18 stainless steel prohibited the oxidization of Cr3+ to form Cr() and formation of passive film consisting of CrO42- or/and Cr(), and make the passive range to …

Biofilm is one of the main factors that influence metal corrosion in seawater environment. According to the structure and property of biofilm, a natural biopolymeric gel,calcium alginate(an extracellular biopolymer containing carboxylate functional groups) can deposite on metal surfaces to form films. Corrosion behavior of alloyed steel E 2, 10CrMoAl and 18_8 stainless steel were studied in simulated biofilm environment by various electrochemical methods,including measurements of the corrosion potential,polarization curves,galvanic current and electrochemical impedance.The results show that such an approach is informative to reveal “how” and “to what extent” biofilm can influence the metal corrosion process.
