Lignin, one of the most naturally abundant polymers, has been successfully incorporated into ethylene glycol (EG) and poly(ethylene glycol) (PEG) in this work and fortified lubricating properties were achieved in EG/lignin and PEG/lignin. The molecular interaction between lignin and EG (or PEG) has been revealed as hydrogen bonding, which serves as the dominating factor that determines the thermal, rheological, and tribological properties of the mixed systems of EG/lignin and PEG/lignin. The physicochemical properties of the mixed lubricants are tightly related to the state of internal hydrogen bonding (EG−EG, PEG−PEG, EG−lignin, PEG−lignin, and lignin−lignin) and are well correlated to their lubrication properties. Generally, larger lignin fractions lead to better lubricating performance in both EG and PEG systems. Lignin liquefaction in PEG has been addressed by catalytic degradation with the presence of sulfuric acid, which was then neutralized by triethanolamine for lubricant development. Lignin in PEG significantly improves the lubricating property at higher pressure conditions, where a wear reduction of 94.6% was observed. Lignin fortified EG and PEG based lubricants show outstanding noncorrosive characteristic to the mostly used metal materials such as aluminum and iron.

“…Peak b 1 is believed to be corresponding to the oxidation of Pb to PbO, and b 2 the chemical reaction of Pb, PbO or PbCrO 4 to PbO 1+x (0 < x < 1). 22 While peak b 3 is very likely to be corresponding to the reaction to form β-PbO 2 from PbCrO 4 , PbO 1+x or a little Pb. For cathodic scanning of Cr ion solution, cathodic peaks b 4 and b 5 are obviously found at peak potential of 1.35 V and −0.6 V, respectively, which should be corresponding to β-PbO 2 be reduced to PbCrO 4 and PbCrO 4 to Pb, respectively.…”

This work examines the change of surface properties and the reaction process of lead alloy anode in CrO3 solution under conditions of high current density, by means of SEM, EDX, XRD, electrochemical test and Raman spectroscopy, for understanding the corrosion mechanism of lead alloy anode. In the initial oxidation stage of lead alloy anode, the diffraction peaks of monoclinic PbCrO4 and PbO are clearly shown in the XRD spectrum of the lead alloy surface. With increasing reaction time, PbCrO4 and PbO diffraction peaks are weakened and those of lead dioxide strengthened. Cyclic voltammetry reveals that the electrode potential change is among Pb, PbO, PbCrO4, PbO1+x (0 < x < 1) and β-PbO2. According to impedance tests, charge transfer and a corrosion product film on lead alloy surface happen under the high and medium frequencies, and chromium-oxide ion clusters are absorbed on free sites of the anode surface for the low frequency. The corrosion products have characteristic of complex semiconducting behavior shown in the Mott–Schottky plots. Raman spectra indicates that Cr2O72− and HCrO4− ions are firstly absorbed on the anode surface, and then PbCrO4 is produced between Cr2O72− and Pb, PbO is reacted from HCrO4−. The mechanism of the anode reaction at the anode/solution interface is discussed using the experimental results.

“…InOOH Accordingly, the anode dissolves continuously as Pb 2+ and [In(OH) 4 ] − without passivation. Then, the anode potential rises very rapidly at B (active-passive transition) to the inflection potential C. This behaviour can be attributed to the oxidation of Pb 2+ to -PbO 2 as the following [32]:…”

The influence of indium content on the anodic behaviour of Pb-In alloys in 4 M H2SO4solution is investigated by potentiodynamic, potentiostatic, chronopotentiometric, and cyclic voltammetric techniques. The composition and microstructure of the corrosion layer on Pb-In alloys are characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy analysis (EDX), and scanning electron microscopy (SEM). The potentiodynamic and chronopotentiometric curves show that the anodic behavior of all investigated electrodes exhibits active/passive transition. The active dissolution (except for alloy I) and passive currents increase with increasing both In content and temperature. This indicates that the conductivity of the anodic film on Pb-In alloy is enhanced. This study exhibits that indium catalyses the oxidation of Pb (II) to Pb (IV) and facilitates the formation of a more highly conductive corrosion layer on lead. Alloy I (0.5% In) exhibits that the corrosion rate is lower, while the passive current is higher than that of Pb. XRD, EDX, and SEM results reveal that the formation of both PbSO4and PbO on the surface decreases gradually with increasing In level in the alloy and completely disappear at higher In content (15% In). Therefore, recharge of the battery will be improved due to indium addition to Pb.
