Electrochemical and corrosion behaviour of nitrogen and boron implanted ARMCO iron
The electrochemical behaviour and pitting corrosion resistance of ARMCO iron specimens implanted with nitrogen or boron ions have been studied.
The electrochemical measurements were performed in different solutions in order to characterize material behaviour under most usual work conditions. The following solutions were employed, (a) 0.5M H2SO4 deaerated solution, to study the active corrosion; (b) 0.15N H3BO3 + 0.15N Na2B4O7 · 10 H2O, pH 8.5, to study the passivating condition; (c) solution (b) + 2400 p.p.m. of Cl− to study the passivity breakdown; (d) 1M NaCl, pH 4, to study the pitting corrosion.
The implantation affects the anodic dissolution of iron, lowering the intergranular attack and enhancing the protective capacity of the oxide layers, modifying the pit nucleation and growth.
Scanning Electron Microscopy (SEM) was used in order to study the surface morphology.
