摘　　要：用原子光谱吸收仪测定了复合涂层试样在不同温度下的镁合金液中浸泡1 h后,镁合金中Fe含量的变化。当温度不高于750℃时,镁合金中Fe元素含量增加很微弱,表明复合涂层能有效防止碳钢坩埚对镁合金的二次污染;用热冲击法定性地分析了复合涂层的热稳定性,在镁合金熔炼温度范围内,涂层与碳钢基体结合良好。The content of Fe in the magnesium alloy,composited coating specimen soaked in it in different temperature after one hour,was measured by atomic absorption spectroscopy. It showed that the content increased faintly when temperature didn＇t exceeded 750 ℃. The thermal stability of the composite coating was analyzed by heat shock. The coating combined well with the carbon steel substrate when temperature was in the melting temperature range of magnesium alloy.

关 键 词：复合涂层 Fe含量 热稳定性
