The corrosion resistance of metal-N double-element alternate implanted M50NiL bearing steel was investigated by potentiodynamic polarization and detection methods of SEM, XPS, AES and TEM. The results showed that ion implanted M50NiL can increase the corrosion potential of substrate, reduce the corrosion active points and inhibit the corrosion reaction induced at the grain boundaries. The formed amorphous layer and strengthening phases take main roles in improving the corrosion resistance of M50NiL bearing steel.

Corrosion Reaction

Copper in hot rolling copper-containing steel plate can passivate the cathode-anode of corrosion reaction on plate surface and form a dense anti-rusting layer, so the rusting reaction is postponed and prevented, and the corrosion resistance is enhanced. However, copper enrichment around grain boundaries in copper-containing steel plate leads to the formation of net-like surface cracking called copper-brittleness. In this paper, through researching the technologies of smelting, and adding rare earth and heating, a reasonable and feasible production technology is found, which effectively prevents the defect of copper-brittleness.

Corrosion Reaction

The influence of Sn on mechanical properties and CO2 corrosion resistance of oil tube was investigated by TEM, EBSD and electrochemical measurement. The results show that the addition of 0.05%Sn can improve the corrosion-resistance of tested steel, but decrease the elongation and impact energy. Sn affected the activity of tested steels, moved corrosion potential to negative potential and decreased corrosion current density. Consequently, the polarization resistance of electrode reaction increased and corrosion reaction was slowed down due to the effect of Sn. In addition, Sn increased the proportion of low boundary, which improved the corrosion resistance of steel, and accordingly decreased the proportion of large angle grain boundary, which contaminated the elongation and impact energy of steel. However, Sn had little influence on the microstructure, precipitates of steel. And thus the strength of steel did not change obviously.

AbstractThe Mo/ZrO2 electrode was prepared by combining hydrothermal synthesis with powder metallurgy, and this new electrode material has a totally different microstructure from the conventional electrode. The grain size of the new electrode was fine, and the size of ZrO2 in the alloy reached 200 nm. According to the results, the Mo–ZrO2 electrode has better performance, because the erosion occurs along the grain boundaries. Meanwhile, the new electrode, based on its fine grain, can effectively improve the corrosion resistance of the electrode.

A rhodamine-based fluorescent compound, spiro[1H-isoindole-1,9′-[9H]xanthen] -3(2H)-one, ′,6′-bis(diethylamino)-2-[(1-methylethylidene)-amino] (RB1), is developed to detect and inhibit the refractory steel corrosion in 3% NaCl solution. The inhibition effect was evaluated by electrochemical measurements. RB1 suppresses the cathodic corrosion reaction and shifts the corrosion potential toward more negative values. RB1 exhibits a turn-on fluorescence emission in the presence of Fe 3+ ions. The selectivity of RB1 over other commonly coexistent Cu2+, Fe 2+ and Mn2+ was investigated. The variation of the fluorescence intensity is correlated to that of weight-loss. RB1 has a potential application as corrosion inhibitor and corrosion indicator in some industry process.
