Microstructure and tribological properties of Fe-Mo alloy-coated steel specimens prepared by low-pressure plasma spraying

► Metastable BCC and FeMo films were obtained by plasma spraying Fe7Mo6 alloy powder. ► The metastable BCC and FeMo films exhibited friction coefficients as low as 0.1. ► The metastable BCC film exhibited micro-Vickers hardness as high as the FeMo film.
