Dynamic model of single discharge during microarc oxidation

Theoretical Foundations of Chemical Engineering, 2015
A dynamic model of microdischarge with a mobile liquid cathode was presented. The possibility of electron autoemission was substantiated. It was suggested that the liquid cathode rate be calculated by the Navier–Stokes equation. A scheme that shows the development of a plasma formation depending on the thickness of the coating was given.

Microarc oxidation-PBAT composite coating on EK30 biodegradable magnesium alloys to enhance corrosion resistance and cytocompatibility.

Colloids and Surfaces B: Biointerfaces
The rapid degradation rate of biodegradable magnesium alloys restricts their use in medical implants. Therefore, designing a protective coating with a slow degradation rate and good biocompatibility is crucial.

Thickness Evaluation of Ceramic Coatings Formed by Microarc Oxidation

Metallurgist, 2021
A thickness distribution model of a coating formed under microarc oxidation of aluminum and its alloys is considered for two extreme cases: a point cathode and a cathode parallel to the sample surface. In the case of the point cathode, the change in the thickness of the formed aluminum coatings was determined. It was experimentally established that the

Microarc Oxidation Coatings on Aluminum Alloy Drill Pipe

Materials Performance, 2017
To improve service life, oxide coatings are deposited on the surface of aluminum alloy drill pipe for offshore platforms by microarc oxidation (MAO) technology. This work focused on an experimental study to determine the effect of cathode voltage on the morphology, phase composition, and corrosion performance of MAO coatings.
