采用传统控制和模糊PID两种方法进行了Mg2Ni镁合金感应熔炼控制,利用XRD、SEM和EDS分析了合金的物相组成、显微组织和微区成分,并进行了电极性能和耐腐蚀性的测试与对比分析。结果表明,与传统控制技术相比,采用模糊PID技术进行Mg2Ni合金感应熔炼控制,可使Mg与Ni完全反应,合金中黑色空洞更少、微区成分更均匀、放电容量增加26.18%、腐蚀电位正移24.11%,合金的电极性能和耐腐蚀性能得到提高。
The induction melting control of Mg2Ni magnesium alloy was carried out by two methods of traditional control and fuzzy PID. The phase composition, microstructure and micro-composition of the alloy were analyzed by XRD, SEM and EDS. The electrode properties and corrosion resistance Test and comparative analysis. The results show that, compared with the traditional control technology, the fuzzy PID technology for induction melting of Mg2Ni alloy can completely react Mg and Ni. The alloy has fewer black holes and more homogeneous micro-zone composition, and the discharge capacity increases by 26.18%. The corrosion potential Positive shift 24.11%, the alloy electrode performance and corrosion resistance is improved.
