摘要
对照普通铝合金,研究了SiCp/2024复合材料在NaCl水溶液中进行拉伸时的开路电位变化。发现复合材料有着完全不同于铝合金的开路电位变化规律。它的开路电位变化由材料在塑性变形时表面氧化膜的破损引起,复合材料特有的屈服与流变特征决定了其独特的开路电位变化规律。
In comparison with the usual aluminum alloy, the open circuit potential of SiC_P/2024 composite as tensed in NaCl solution is investigated. The open circuit potential of the composite varies in a way quite different from that of the aluminum alloy. Variation of the open circuit potential is caused by damage of the surface oxide film during plastic deformation of the material. The characteristics of the composite's yield and flow decide its unique variation regularity of the open circuit potential,
