Corrosion resistance of PEO and primer coatings on magnesium alloy

Microscopic Analysis of the Surface Morphology of Multilayer Structures of the AluminumAlloy - Silicon Type after Water Jet Cutting

“…Their results are consistent with the results obtained in this article, but they concern composites with a slightly different structure. This is also confirmed by other authors of publication [22,24,25], in which aluminum -rubber materials are cut. With reference to the research results presented in this publication, the authors of other publications note similar phenomena occurring in the interfacial zone.…”

“…The current state of the writer describes many phenomena that occur in the interfacial zone and characterizes them. Referring the results of this work to other works carried out on SEM microscopes [24,25] appearing in the literature, such an analysis allows for the correct synthesis of the phenomena of joined materials.…”

“…In order to obtain an even distribution of stresses at the metal/polymer interface, the structure must be symmetrical, and the metal surface should be characterized by high stiffness. The composition of multi-layer structures with more than two connection surfaces provides increased impact strength and fatigue resistance, due to the extensive surface between individual layers, which is an effective barrier for the formation of cracks and delaminations.This is confirmed by the analyses of interfacial structures carried out with the use of a scanning electron microscope [24] [24].…”

Predicting localised corrosion and mechanical performance of a PEO surface modified rare earth magnesium alloy for implant use through in-silico modelling

“…For detailed description of corrosion mechanisms associated with PEO and bioabsorbable magnesium alloys we refer to Refs. [ 15 , [76] , [77] , [78] , [79] ]. Finally, despite the good prediction of several geometrical corrosion features using the surface-based degradation model, it was noticeable that it does not correctly capture the pit density, which arises due to the chosen element size (80 μm).…”

Active Corrosion Protection by Epoxy Coating on Li2CO3-Pretreated Anodized Aluminum Alloy 2024-T3

“…Many researchers performed the plasma electrolytic oxidation (PEO) and micro arc oxidation (MAO) on Mg and Al alloys to obtain the porous structure that solved the relative adhesion problems of polymer top coatings on the surfaces. Furthermore, the PEO and MAO surfaces acted as containers to store different inhibitors, and the pH changes provided active corrosion protection in the defect area and improved its barrier properties (Golabadi et al, 2017a;Yang et al, 2018a;Yang et al, 2018b;Pezzato et al, 2019;Toorani et al, 2020;Liu et al, 2021;Ostapiuk, 2021;Toorani et al, 2021;Zeng et al, 2021;Zhang et al, 2021). Golabadi et al (2017b) showed that the compaction and cathodic disbondment of the epoxy coating were enhanced on the phosphated coating consisting of different additives.…”
