Reactive plasma spraying synthesis and characterization of TiB2–TiC–Al2O3/Al composite coatings on a magnesium alloy.

Highlights: [•] Synthesis of TiB2–TiC–Al2O3/Al composite coatings on Mg alloy by RPS. [•] Microstructure and properties of the RPS coatings were characterized. [•] The coatings consist of TiB2, TiC, Al2O3 and/or excess Al without by-products. [•] The coatings display dense structure and good interfacial bonding with substrate. [•] The coatings provide good protection for the Mg alloy against wear and corrosion. [ABSTRACT FROM AUTHOR]
