This work contributes to the development of new feedback-active anticorrosion systems. Inhibitor-doped hydroxyapatite microparticles (HAP) are used as reservoirs, storing corrosion inhibitor be released on demand. Release entrapped is triggered by redox reactions associated with process. HAP were reservoirs for several inhibiting species: cerium(III), lanthanum(III), salicylaldoxime, and 8-hydroxyquinoline. These species effective inhibitors a 2024 aluminum alloy (AA2024), here model...
Severe corrosion of Mg and alloys is a major issue hindering their wider application in transportation industry, medical implants aqueous batteries. Previously, no Mg-based material has been found with significantly lower rate than that ultra-high-purity Mg, i.e. 0.25 mm y-1 concentrated NaCl solution. In this work for the first time, highly corrosion-resistant to be accomplishable by Ca micro-alloying, bringing "stainless Mg" closer. The designed Mg-Ca lean possess incredibly low rates,...
2,6-pyridinedicarboxylate (2,6-PDC) was studied as corrosion inhibitor for pure magnesium. The surface prepared either by polishing or followed treatment with 1 M NaOH solution. results show that 2,6-PDC promotes the formation of a denser protective oxide/hydroxide layer poor in PDC. mechanism proposed includes forming weak PDC-Mg complexes lower free Mg2+ concentration available Mg(OH)2. This leads to growth smaller Mg(OH)2 platelets are more densely packed and hence form layer. highest...
This study focuses on the development of a physico-chemical model based mechanistic and kinetics understanding corrosion process in galvanic couple Ti6Al4V-AA2024. Proposed provides deeper insights at macro level for initiation propagation localized AA2024 galvanically coupled multi-material assemblies. The is able to reveal corrosion, related heterogeneity microstructure, including local pH changes, deposition reaction products, emphasizes important role self-corrosion validation developed...
Mg-air primary battery has become an attractive source of energy due to its economic viability, environmental benignity, and high theoretical specific power density. However, low practical delivered self-corrosion fast anode fouling are the main reasons that limit their commercial application. Modification electrolyte chemistry in batteries plays a crucial role improving performance. In this study, impact addition two strong complexing agents at different concentrations aqueous is...
