摘要:
为提高挤压态Mg-1.5Zn-0.5Y-0.5Zr合金的耐蚀性能,研究了不同固溶温度对其耐蚀和力学性能的影响,通过微观组织观察、电化学测试、体外浸泡实验、拉伸实验研究了固溶处理后样品的微观组织与性能。结果表明,固溶处理后合金中的W相减少,耐蚀性能提高,但当温度达到550 ℃时,会进一步造成晶粒粗化,降低了合金的耐蚀性能。合金的强度和塑性随着固溶温度的升高而降低。综合固溶处理后合金的耐蚀和力学性能,推荐500 ℃为最佳固溶处理温度。
Abstract:
In order to improve the corrosion resistance of extruded Mg-1.5Zn-0.5Y-0.5Zr alloy, the effects of different solution treatment temperature on its corrosion resistance and mechanical properties were studied. The microstructure and properties of the samples after solution treatment were studied by microstructure observation, electrochemical test, in vitro immersion test and tensile test. The results show that the W phase in the alloy is reduced and the corrosion resistance is improved after solution treatment. However, when the temperature reaches 550 ℃, further grain coarsening occurs, which reduces the corrosion resistance of the alloy. After solution treatment, the strength and plasticity of the alloy decrease with the increase of solution temperature. Based on the corrosion resistance and mechanical properties of the alloy after solution treatment, 500 ℃ is recommended as the best solution treatment temperature.
