“…It is known that the size of micropores and their distribution on the surface can vary depending on the coating parameters. 12,[16][17][18][19][20][21]26,27 Figure 1 shows that in the Experiment-4 parameter (500 Hz, 550/−80 V, 5 min), the number of micro-voids is relatively less and the diameter of the micro-voids is smaller. It is thought that in Experiment 3 (500 Hz, 450/ −80 V, 15 min), the current values that continue during the coating period are at lower levels compared to the other experiments, causing the micro-voids to be more regular in small diameter.…”

“…12,15–17,14–27 These micropores and flat structures result from continuous localised discharge events associated with molten metal oxide deposition and disperse on the coating surface. 26–29 As can be clearly seen from the surface morphologies of the coatings in Figure 1, flat structures with numerous circular micro-voids were found on the surfaces of all samples. It is known that the size of micropores and their distribution on the surface can vary depending on the coating parameters.…”

Magnesium–lithium alloy is used in different areas of industry and is known as a super light metallic engineering material. However, the use of these alloys is limited due to their surface properties under extreme loads and aggressive environments. Surface treatments can be applied to these alloys to increase their usage areas and improve their weak surface properties. In this study, the micro-arc oxidation method was applied to improve the surface properties of LA91 alloy. The corrosion and adhesion behaviour of the coated samples were investigated. The lowest corrosion current density in the coatings was obtained under Experiment 3. Experiment 3 has the highest Lc2 value due to the coating thickness and the denser and smaller diameter pores of the functional intermediate layer.

“…Li-MAO coating was also reported to have better osteogenic ability according colorimetric method (MTT) and quantitative polymerase chain reaction (qPCR) analyses. Ma et al [ 60 ] showed that MAO coating containing B 4 C/C particles prepared on an Mg-Li alloy had a better corrosion resistance. The addition of B 4 C/C particles resulted in a decrease in porosity in the MAO coating.…”

“…It was observed that the coating with Mg-14Li-3Al-1Y backing material was the most corrosion resistant combination with 7.485 × 10 icorr. Ma et al (2022b), made coatings by adding boron carbide and carbon particles on the Mg-Li substrate by the plasma electrolytic oxidation method. The effect of the added B4C and C particles on the microstructure was investigated.…”

Coating processes are carried out in many areas of industry to improve the surface properties of materials such as wear and corrosion resistance or appearance. One of these coating processes is ceramic-based surface coatings. In order to obtain harder, denser and more uniform coatings, the substrate material is coated with a ceramic-based material at the desired thickness. In this study, 7075 series aluminum was coated with nano Ti powder and non-additive micro arc oxidation (MAO) method in a solution consisting of KOH, NaAlO2 and Na3PO4, and the effects of process parameters on coating thickness and wear behavior were experimentally investigated and the results were analyzed. According to the results obtained, it was observed that as the coating voltage, frequency and coating time increased, the wear rate decreased and a harder structure against wear is obtained. In addition, it was determined that the samples with nano titanium powder were less worn than the non-additive samples. According to SEM, EDX and XRD analyses, Al2O3 phase was observed in the coatings made without adding titanium particles; It has been observed that in addition to the Al2O3 main phase, TiO2 and SiO phases are also formed in titanium doped coatings.
