Evaluating the performance of MoS₂ based materials for corrosion protection of mild steel in an aggressive chloride environment

Abstract

The incorporation of Fe, Co, and Ni ions resulted in an appreciable increase in the corrosion resistance properties of MoS2.

Study on the galvanic corrosion of aluminum alloy single bolted lap joints in simulated atmospheres

“…In the thin layer electrolyte, as well as on the metal surface, a non-uniform distribution will occur in the potential, current, and resistance to mass transfer. [7] Different thicknesses of the thin layer electrolyte on the metal surface result in different corrosion rates. Figure 2 qualitatively indicates the relationship between the atmospheric corrosion rate and the thickness of the thin layer electrolyte on the metal surface.…”

“…Under the thin layer electrolyte condition, the traditional electrochemical test method cannot accurately measure the micro‐electrolytic system. In the thin layer electrolyte, as well as on the metal surface, a non‐uniform distribution will occur in the potential, current, and resistance to mass transfer . Different thicknesses of the thin layer electrolyte on the metal surface result in different corrosion rates.…”

Emerging Layered Materials and Their Applications in the Corrosion Protection of Metals and Alloys

“…Good corrosion protection and durability was seen with the MoS 2 -containing sunflower coating, and this was attributed to the formation of a highly ordered barrier coating. Likewise, ArunKumar et al [155] dispersed MoS 2 and doped MoS 2 in sunflower oil, and found that doping MoS 2 with Fe, Co, and Ni ions resulted in an increase in the corrosion-protective properties of MoS 2 . For example, the corrosion current of mild steel was measured as 83 × 10 −6 A cm −2 in a chloride-containing solution.…”

Two-Dimensional Nanomaterials for Anticorrosive Polymeric Coatings: A Review

“…The most studied TMDCs in organic anticorrosion coatings are molybdenum disulfide (MoS 2 ) nanosheets. Because MoS 2 has good chemical and thermal stability, this contributes to the corrosion resistance of the coating. − However, layered MoS 2 nanomaterial has a tendency of severe agglomeration in polymer composites. Therefore, the surface organic functionalization of MoS 2 (including noncovalent and covalent modification) is usually used to improve its dispersibility , (Figure ).…”
