Abstract

The structure and physico-mechanical properties of coatings of the quasicrystal alloy Al63Cu25Fe12 produced by plasma spraying are investigated. Modification of structure of the sprayed alloys depends on spraying modes, in particular, on substrate temperature. The optimum temperature range of substrate (600 °C < T < 700 °C) which provides the maximum content (up to 80%) of quasicrystal phase is determined. The correlation between level of mechanical properties and content of icosahedral phase in the coating is established. It is revealed that allocation of nanostructural grains (d < 100 nm) resulted in additional increase of mechanical characteristics.
