FIELD: metallurgy, in particular coating gas composition for protection of melted magnesium of magnesium-based alloys.
SUBSTANCE: claimed coating gas composition includes at most 1 vol.% of fluorinated inhibitor and carrier gas. Each composition component has Global Warming Potential (GWP) (as referred to absolute GWP of carbon dioxide at decomposition time of 100 years) less than 5000.
EFFECT: high effective protection of melted magnesium of magnesium-based alloys.
