Abstract

Foundry magnesium alloys are used for the manufacture of complex-contoured castings of variable cross-section, during the production of which metallurgical defects may occur, such as underflows, small cracks, tears, shells, and microporosity. The use of gas-dynamic spraying of special powder compositions without heating is the most economical modern technological method to eliminate these defects. The article presents the results of scientific and technical research on the development ofpowder compositions for casting magnesium alloys of Mg–Al–Zn, Mg–Zn–Zr, Mg–REM–Zr systems.
