“…29-0914). 46 The XRD pattern of the AgNFs/MWCNTs not only shows the characteristic peaks of the AgNFs but also a small and wide peak at about 281. The diffraction peak of MWCNTs at 471 is masked by the diffraction peak of AgNFs at 44.091, which resulted in MWCNTs showing only one peak in the composite.…”

Organic corrosion inhibitors from natural plant resources have received extensive attention in recent years. Herein, an eco-friendly corrosion inhibitor lignin-(2,3-epoxypropyl)trimethyl ammonium chloride (EPTAC) was successfully prepared by grafting EPTAC to kraft lignin. The inhibiting efficiency and its inhibition mechanism were investigated using electrochemical methods, adsorption thermodynamics analysis, and molecular dynamic simulation. The results showed that the lignin-EPTAC molecules formed a protective film on iron surface, resulting in an excellent inhibition efficiency of 97.80% at 100 mg/L concentration. The average surface roughness of steel samples was reduced to 26.6 nm from the original 99.3 nm. The adsorption of lignin-EPTAC molecules on the steel surface follows Langmuir adsorption isotherm model and was a physical-chemical process as well as an exothermic process of entropy reduction. This adsorption of lignin-EPTAC was a conjugated system dominated by benzene ring of lignin-EPTAC to form a chemical bond on the steel surface by conjugation, besides a positive interaction between the metal surface and the positively charged N ions in the head group of lignin-EPTAC.

“…16 Besides, the particles of low surface free energy, for example, sulphides of molybdenum and sulphur are beneficial to obtain a super-hydrophobic coating. 17,18 A wide range of literature work has been already reported on the EDC of hard and soft solid lubricant powders to improve the surface integrity and tribological properties of coating. However, a limited range of research work has been carried out on exploring the wetting properties of coating prepared by simple EDC process.…”

Electrical discharge coating (EDC) process has been used to prepare a corrosion and wear resistant super-hydrophobic coating on the steel substrate. The coating process has been carried out by using three types of green compact tool electrodes (WS2/Cu, MoS2/Cu, and hBN/Cu). In these tool electrodes, powder mixing ratios (40:60, 50:50, 60:40) are varied, and their effect on coating characteristics (surface morphology, wettability, corrosion, and wear behaviour) has been studied. In this investigation, the morphology and chemical state of coating has been observed by using a scanning electron microscopy (SEM) and X-ray photoemission spectroscopy (XPS). SEM images of the applied coating show a porous and hierarchical structure. This hierarchical structure helps in raising the contact angle (CA) to 165.6° (super-hydrophobic state). The XPS analysis reveals that the deposition of solid lubricants takes place with their negligible disintegration into non-lubricating compounds. In addition, the prepared coating exhibits excellent resistance to wear and corrosion.
