Compositional variations in the coatings formed by detonation spraying of Ti3Al at different O2/C2H2 ratios

► The Ti3Al phase is preserved during detonation spraying in a reducing atmosphere. ► Ti3Al is oxidized at O2/C2H2 ratios 1.50 and 2.00 to form titanium oxides. ► Al losses occur in oxidizing conditions of detonation spraying of Ti3Al powders.
