“…Generally, the large concentrations improve solution conductivity and provide sufficient reactants on the interfaces to expedite the corrosion process. [ 74 ] 2)Diffusion rates of ions/oxygen gases: the corrosion reaction actually involves the diffusion of different ions and oxygen gases on the surfaces of metal substrates, while the faster diffusion rates always bring forth the severer corrosion. [ 75,76 ] Employing vigorous stirring for the accelerated convection is the commonly used method to promote diffusion rates, which can be used to shorten the reaction time of corrosion engineering and enhance the homogeneity of target materials. 3)Surrounding atmosphere: herein, oxygen corrosion is adopted as an example, which can only happen in the oxygen‐containing atmosphere.…”

Producing high‐purity hydrogen from water electrocatalysis is essential for the flourishing hydrogen energy economy. It is of critical importance to develop low‐cost yet efficient electrocatalysts to overcome the high activation barriers during water electrocatalysis. Among the various approaches of catalyst preparation, corrosion engineering that employs the autogenous corrosion reactions to achieve electrocatalysts has emerged as a burgeoning strategy over the past few years. Benefiting from the advantages of simple synthesis, effective regulation, easy scale‐up production, and extremely low cost, corrosion engineering converts the harmful corrosion process into the useful catalyst preparation, achieving the goal of “transforming damage into benefit.” Herein, the concept of corrosion engineering, fundamental reaction mechanisms, and affecting factors are firstly introduced. Then, recent progresses on corrosion engineering for fabricating electrocatalysts toward water splitting are summarized and discussed. Specific attentions are devoted to the formation mechanisms, catalytic performances, and structure–activity relations of these catalysts as well as the approaches employed for performance improvements. At last, the current challenges and future exploiting directions are proposed for achieving highly active and durable electrocatalysts. It is envisioned to shed light on the multidisciplinary corrosion engineering that is closely associated with corrosion and material science for energy and environmental applications.

“…The pH value of IWP is 9.64 because it contains alkaline oxides such as iron and calcium oxides. The CR can be slowed down in alkaline mediums due to the formation of a protective passive film of insoluble metal hydroxides . However, the presence of copolymer on the IWP surface reduced the pH value of the COIW to 6.06.…”

The purpose of this article was to evaluate the performance of a poly(aniline‐co‐anisidine)/iron waste composite (COIW) as an anticorrosive pigment for primer coatings. A procedure was outlined to prepare COIW and evaluate its anticorrosive properties following the electrochemical behavior and corrosion test of the coated steel. Various zinc‐rich epoxy primers were formulated by replacing part of the zinc powder (ZP) pigment with COIW. In all formulas, the ratio of pigment to epoxy resin was fixed at 2. In the pigment mix, the percentage of COIW was ranged from 5% to 60% by weight to the ZP. The performance of the formulated primers was estimated by the salt immersion test and potentiodynamic polarization measurement (corrosion potential, polarization resistance, and corrosion rate essays). It was demonstrated that COIW is effective in protecting steel from corrosion when it is used in combination with ZP.

A corrosion-resistant non-crystalline coating was fabricated by plasma electrolytic oxidation (PEO) on Q235 low carbon steel for ship pipes. The distribution and composition of chemical elements and phases of PEO coatings were analyzed by an orthogonal experiment, and the formation mechanism of PEO coatings was discussed. The corrosion current densities and corrosion potentials were measured. The results indicated that the formation of a transition layer mainly containing Fe3O4 was crucial for achieving an excellent coating quality. Furthermore, the corrosion current density of coated steel was reduced by 78% compared with the bare steel.
