Analysis of the state-of-the-art in methods for manufacture of powders of quasi-crystalline alloys has been conducted. It is shown that the most suitable method to manufacture powders for thermal spraying, among those available now, is compressed air atomisation of the melt, which provides powders with a high content of the quasi-crystalline phase and high workability (flowability).
Keywords: thermal spraying, coating, powder, quasi-crystalline icosahedral-phase, manufacturing methods, workability of powder
