摘要

研究了HFC-152a气体对镁及其合金在熔炼过程中的保护效果

并对其保护机理进行了探讨。结果表明

含体积分数为0.1%的HFC-152a保护气体可以较好地起到保护作用;气体浓度越高

温度越低

保护效果越好;试样的扫描电镜、X射线衍射分析显示氧化膜很致密

它由MgO、MgF、Mg等组成

起到了保护作用。

Abstract

Protections of HFC-152a atmosphere on Mg and its alloy during melting have been investigated

and the protection mechanism is analyzed. The results show that the atmosphere containing 0.001 mol/L HFC-152a can better protect the Mg and its alloy during melting. The higher the gas concentration is and the lower the melting temperature is

the better the protection effects are. The TEM and XRD analysis show that sound oxidized film is composed of MgO and MgF

possessing better protection effects on the magnesium and its alloy.
