采用恒定的超声功率、频率和施振深度,在不同温度区间对Pb-Ag合金熔体施加超声振动,探讨功率超声对Pb-Ag合金的显微组织及电化学性能的影响。结果表明,随着熔体温度的升高,超声空化效应和声流作用发挥的越充分,过低或过高的熔体温度因超声处理不充分或熔体内部热效应,均导致晶粒粗大。仅在370℃保温条件下,超声波处理能使组织显著细化均化,电化学性能提升,电阻率下降12.95%,极化电位负移290 m V,槽电压下降1.77%,达到了一定的节能降耗的目的,为今后制备高性能低能耗的Pb-Ag合金电极奠定基础。 Ultrasonic vibration was applied to Pb-Ag alloy melt at different temperature intervals with constant ultrasonic power, frequency and vibration depth to investigate the effect of ultrasonic power on the microstructure and electrochemical performance of Pb-Ag alloy. The results show that with the increase of the melt temperature, the cavitation effect of ultrasound and the fuller effect of the acoustic flow are played. The melt temperature which is too low or too high, due to the insufficient ultrasonic treatment or the internal thermal effect of the melt, leads to coarse grains . Under the condition of 370 ℃ heat preservation, the microstructure was refined and homogenized with ultrasonic treatment. The electrochemical performance was improved, the resistivity decreased by 12.95%, the polarization potential shifted by 290 mV and the cell voltage decreased by 1.77% Reduce consumption, and lay the foundation for the future preparation of high performance and low energy consumption Pb-Ag alloy electrode.
