摘要	Although α-Al2O3 is commonly used as crude materials for preparing Al2O3 coating by plasma spraying, the obtained coatings are mainly made up of γ-Al2O3 crystalline phase with relatively poor mechanical performance. In this research, we employed an unconventional way, i.e. adopting low-cost γ-Al2O3 powders as crude material via the optimisation of plasma spraying process to prepare a novel aluminium oxide coating containing α-Al2O3 crystals with excellent mechanical properties as main phase, and the microstructure, microhardness and tribological properties of the coating were characterised and analysed. The results indicated that the aluminium oxide coating possesses favourable toughness, strength and wear resistance (e.g. HV602.4 and wear loss ∼2.5 μm), consequently having a great potential for exploration and application. © 2018, © 2018 Institute of Materials, Minerals and Mining Published by Taylor & Francis on behalf of the Institute.
