“…As explained earlier, the microwave-assisted technique did not have any adverse effects on the La structure; rather, it accelerated the process, and this study moved one step forward, where La was added after plasma electrolytic oxidation (PEO) coating was conducted. Briefly, PEO is an advanced electrochemical surface treatment method (also named microarc oxidation (MAO)) that involves applying an extremely high voltage to a suitable electrolyte to generate a plasma state. , This technique easily enables the formation of oxide layers on metallic alloys, resulting in improved surface properties, such as increased hardness, wear resistance, and corrosion resistance. It can be clearly seen that he coating obtained at 50 °C, under 30 min treatment, produced the best results, as shown in cross-sectional images in Figure (k) as compared to the porous and cracked coatings obtained at 30 °C (Figure (i) and 40 °C (Figure (j)), during the same time duration of 30 min.…”

“…The backscattered micrograph of the cross-sectional features in Figure 6(c) and Figure 6(d) show the structure of the MAO coatings. The resulting coatings contained porosities because oxygen was trapped in the molten oxides formed by localized discharges [19]. The coating in Figure 6(c) was produced for 30 min in the electrolyte without cooling.…”

The electrolyte temperature has a great influence on the performance of the coating prepared by micro-arc oxidation (MAO). The behavior of MAO discharge in the changing electrolyte temperature has been investigated. Compared to constant electrolyte temperature in conventional MAO process, the process has different discharge characteristics under the changing electrolyte temperature. The amplitude of pulse voltage was detected to study the change of discharge characteristic under the constant-current control of MAO power supply. Three successive discharge stages were differentiated by the variable the pulse voltage versus process time. Since there were significant changes in the sound, the sound signals were acquired and the audio analysis was used to describe the changing of the MAO discharge at different stages. Optical emission spectroscopy (OES) was employed in situ to unveil how the micro-discharge changed with the temperature increasing. Scanning electron microscopy (SEM) was used to characterize the morphology of the coatings on 6N01 aluminum alloy prepared by normal process with the constant-temperature control of the MAO electrolyte and by the process under the changing electrolyte temperature. A mode of film growth and microdischarge was given to describe the effects of the changing electrolyte temperature in the whole MAO process.

“…The main method for protecting metals, including aluminum, is the formation of coatings on the surface of a part or product. One of the promising ways to form such protective coatings is plasma electrolytic oxidation (PEO) [ 8 , 9 , 10 , 11 ]. The coatings obtained using PEO have highly protective and wear-resistant properties, high adhesion to the metal substrate, as well as a developed surface with pores; this makes it possible to modify such coatings (by incorporating the various components into the pores) with different materials, depending on the purpose of future use [ 10 , 11 , 12 ].…”

The purpose of this work is to modify such coatings previously formed on AMg3 alloy by introducing superdispersed polytetrafluoroethylene (SPTFE) into their structure using a spray-coating method.…”

This paper presents the results of an investigation of the changes in the corrosion, wear resistance, and wettability of composite coatings formed on the AMg3 alloy through plasma electrolytic oxidation (PEO) and subsequent spraying with an organofluorine polymer. The evaluation of the electrochemical properties of the composite layers revealed a decrease in the corrosion current density compared with the PEO coating (from 3.8 × 10−8 to 3.1 × 10−11 A/cm2). The analysis of the wear resistance of composite coatings established that the application of this type of coating reduced the wear of the samples by two orders of magnitude when compared with the PEO layer. Using the contact-angle measurement, it was found that with an increase in the number of polymer spray applications, the wettability of coatings decreased, so the contact angle for the composite coating with triple fluoropolymer application increased by 134.3° compared to the base PEO coating.
