Summary: Plasma electrolytic oxidation (PEO) is a cost effective and environmentally friendly technology that has been used to improve wear and corrosion resistance in magnesium and its alloys. By incorporating functional particles and/or using post-treatments, the PEO coatings can be further improved to provide multifunctionalities, such as wear resistance, corrosion resistance, self-lubrication, and self-healing. This paper reviews recent progress in PEO composite coatings on magnesium and its alloys, focusing on the microstructural and functional changes of the PEO coatings, particularly in terms of wear and corrosion behaviors.

Summary: In recent years, research has focused on the effects of adding various nanoparticles and chemicals dissolved in electrolytes to chemicals. This paper proposes the idea of using sodium pentaborate in the electrolyte PEO coating on the WE43 magnesium alloy and investigates its tribological and corrosion properties. The results show that the sodium pentaborate additive supports the formation of hard oxide compounds, providing corrosion protection and reducing wear rate in comparison to non-additive PEO coatings. The experimental results suggest that sodium pentaborate can be used as an electrolyte additive for advanced functional coating materials in tribological applications.

Summary: This study investigated the microstructure, tribological and electrochemical corrosion properties of plasma electrolytic oxidation (PEO) coatings with various amounts of carbon nanotube (CNT) additives on AZ80 magnesium alloy substrate in silicate-based electrolyte. The results showed that increasing CNT additions led to thicker coating layers. The addition of 0.5 g/L CNT resulted in a slight decrease in roughness before increasing again. The wear resistance of the PEO-coated specimens improved with increasing CNT-incorporation. The best corrosion resistance was achieved with the addition of 0.5 g/L CNT.

Summary: This study investigated the formation of Mg2SiO4 coatings on cp-Mg using Plasma Electrolytic Oxidation (PEO) with sawtooth anodic current pulses. The results showed that the application of sawtooth pulses allowed for control over coating morphology and microdischarge characteristics. Additionally, it was found that the use of anodic sawtooth pulses with a negative ramp facilitated defect healing during coating formation, resulting in more uniform coatings with lower porosity and slower degradation rate of the magnesium substrate.

Summary: Plasma electrolytic oxidation (PEO) is an effective surface treatment technique for enhancing the corrosion resistance of Mg alloy, but the micro-pores and micro-cracks of the PEO coating can limit its protection capability. In this study, a dense Ca3Al2(OH)(12) layer was fabricated on the PEO coating surface using hydrothermal treatment (HT) to create a PEO/HT composite coating, which showed improved bioactivity and corrosion resistance compared to PEO coating and Mg alloy. The growth process of the Ca3Al2(OH)(12) layer on the PEO coating surface was discussed.

Summary: This study focuses on the preparation of biodegradable calcium phosphate (CaP) ceramic coatings on self-designed Mg-2.0Zn-0.6Ca-xSi alloys through plasma electrolytic oxidation (PEO). The influence of calcium (Ca) and silicon (Si) on alloy microstructure, coating formation, and biomineralization mechanisms were investigated. The in vitro bioactivity and degradability of the CaP coatings were evaluated through immersion tests. The results suggest that the microstructure of the Mg-2.0Zn-0.6Ca-xSi alloys can affect the formation and growth of PEO coatings.
