Abstract

The protective effects of C₂H₂F₄ mixed gases in melting process of magnesium and magnesium alloys have been researched experimentally for the first time. And the mechanisms of protection have been analyzed. The results show that the protective atmosphere of air containing 0.3% C₂H₂F₄ acts fairly protective effect. The thicker the C₂H₂F₄ concentration and the lower the temperature, the better the protection effect. The C₂H₂F₄ mixed gases react with the magnesium melt and form a compact protective film made up of MgO and MgF₂ on the melt surface which acts the protective effect.
