Abstract	Pure and silicon-, indium- and magnesium-doped α-Fe₂O₃ powders have been plasma sprayed on titanium substrates. The resulting coatings were analysed by electron and optical microscopy, thermogravimetry and X-ray diffraction. The results show that Fe₃O₄ is present in all coatings and comes from the reduction of Fe₂O₃. The latter phase is also obtained in most of the coatings and its presence is explained on the basis of a mechanism of re-oxidation of Fe₃O₄. This mechanism is affected by the spraying distance and also by the presence of dopants. These plasma-sprayed coatings have semiconductive properties which can find applications in photoelectrochemical or photocatalytic systems.
