“…The phase angle maxima (θ max ) is much below −90 degrees, indicating a deviation from ideal capacitive behavior. It is known that the |Z| measured from the low-frequency portion of the modulus impedance plot is related inversely to the corrosion rate; thus, a larger absolute impedance assures superior charge transfer resistance at the surface/electrolyte interface [24][25][26][27]. In Figure 10a, the |Z| can be observed to increase with increasing solutionizing duration.…”

The solution annealing of cold rolled super austenitic stainless steel UN08029 alloy was carried out to investigate the role of solutionizing duration and temperature on the electrochemical corrosion and pitting resistance of the alloy. Linear polarization, cyclic potentiodynamic, and electrochemical impedance spectroscopy techniques were used to evaluate the electrochemical behavior in 3.5% NaCl solution. The microstructural analysis of the solutionized samples revealed the formation of uniform equiaxed grains from elongated columnar grains, which size increases with duration and temperature. The charge transfer resistance shows an increasing corrosion protectiveness of 46 to 60% with increasing solutionizing duration from 30 to 120 min. Similarly, a 45, 52, 60, and 26% improvement in the corrosion performance was obtained for sample solutionized at 1000, 1100, 1200, and 1300 °C, respectively. In general, the solutionized samples demonstrated improved resistance over the as-received alloy, and this behavior increases with solutionizing duration and temperature. Though the pitting potential drops below that of the as-received alloy, the hysteresis loop revealed that the solutionized samples are less prone to pitting damage, and the sample solutionized at 1200 °C for 120 min exhibited optimum pitting corrosion resistance. The microstructural influence on corrosion was also discussed.

Thiadiazole compounds and their derivatives have good carrying capacity and lubricating properties. Herein, polydopamine can be in situ self-assembled onto gallium-based liquid metal (GLM) nanoparticles via ultrasound treatment of bulk GLM nanoparticles in dopamine-containing Tris aqueous solution followed by covalent bonding with a thiadiazole dimer (DMCT) through Michael addition reactions. The as-prepared thiadiazole dimer-functionalized liquid metal (GLM-DMCT) nanoparticles, with an average particle size of 380 nm, can be used as nanoadditives in the base oil (500SN). The tribological properties of GLM-DMCT as additives were evaluated under various loads, temperatures, and frequencies, and the results showed that GLM-DMCT additives have improved anti-friction and anti-wear performances of 500SN. The coefficient of friction can be reduced to 0.092 from 0.147 after adding 2 wt % GLM-DMCT, the wear volume reduces by 89.7%, and the load-carrying capacity is increased from 150 to 1050 N. The improved tribological performance is credited to the formation of a stable, protective layer on the friction pair via the complex tribo-chemical reaction of Ga, In, and S elements of GLM-DMCT. Furthermore, the as-prepared GLM-DMCT exhibits good anti-corrosion performance, which is attributed to the breaking of the disulfide bond of DMCT, releasing the corrosion inhibitor DMTD during the corrosion process.

Herein, we analyzed the martensitic transformation kinetics during electrochemical polishing (EP) for stainless steel specimens with varying surface roughness and austenite stability. Martensite fraction measurement demonstrated that specimens with higher surface roughness and lower austenite stability exhibited relatively higher levels of martensitic transformation. To understand these phase transformation characteristics, the amount of charge build-up on the specimen surface during EP was calculated using COMSOL Multiphysics simulations for specimens with different surface roughness. The effect of charge build-up-induced stress was analyzed using previously published first-principles calculations. We found that specimens with higher surface roughness accumulated more charge build-up, resulting in greater stress and a martensitic transformation driving force. Furthermore, the critical energy required for the martensitic transformation was calculated using Thermo-Calc for specimens with different austenite stabilities. We demonstrated that the martensitic transformation kinetics during EP could be explained in terms of austenite stability, similar to the stress-induced martensitic transformation.
