AZ91/SiC composites show a globular microstructure with SiC clusters located at the interglobular regions. PEO coatings reveal a trilayered structure with thicker, less porous and softer regions at the locations of SiC clusters. Corrosion rate increases with increasing the volume fraction of reinforcement, which shows a cathodic activity and disrupts the continuity of the β-phase network. PEO improves the corrosion resistance, but it is also negatively influenced by the presence of the reinforcement. Tribological tests show a positive effect of the reinforcement on uncoated materials, whereas an opposite effect is found on PEO coated materials, probably due to the detachment of SiC particles from the coatingengAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1016/j.surfcoat.2016.10.041https://www.sciencedirect.com/science/article/pii/S0257897216310374open access66620.1Magnesium compositeCorrosionWearSKPFMIngeniería químicaMateriales3303 Ingeniería y Tecnología Químicas3312 Tecnología de Materiales
