Characterization and mechanical properties of coatings on magnesium by micro arc oxidation

Effect of KOH Concentration on the Microstructure and Electrochemical Properties of MAO-Coated Mg Alloy AZ31B

“…In addition, in order to improve the quality of the resulting coatings, increase the electrical conductivity of base electrolyte, and contribute certain elements within the MAO coatings, various additives are added to the base electrolyte (Ref [48][49][50][51][52][53]. It is known that phosphate can produce a sustainable Mg 3 PO 4 ð Þ product to protect the Mg alloys (Ref [54][55][56]. Borate is another additive under investigation.…”

Improving the wear properties of AZ31 magnesium alloy under vacuum low-temperature condition by plasma electrolytic oxidation coating

“…When the concentration reached 5 g/L, fewest micro-pores and cracks was observed (Fig. 1c), which can increase the density and smoothness of coatings [29][30][31]. As a result, the hardness of the PEO coating was improved and the PEO coating obtained by adding 5 g/L NaAlO 2 showed the highest hardness.…”

Biomedical materials and techniques to improve the tribological, mechanical and biomedical properties of orthopedic implants – A review article

“…The PEO technique has been gaining an increasing interest recently as it could provide superior adhesion between the coatings and the substrate and formation of high crystalline coatings with porous surface morphologies [136], [137]. Moreover, the PEO process is a low cost, simple to operate, eco-friendly and versatile [138].…”
