磁场对船用镁合金在模拟海水中的研究

为了研究磁场对船用镁合金在海水中腐蚀及极化行为的影响,采用恒电位极化测试和动电位极化测试对AZ31B在模拟海水中的电流密度和自腐蚀电位进行了研究。结果表明:加入磁场后,可以改变AZ31B镁合金自腐蚀状态,降低了电流密度,提高了材料的耐腐蚀性。

In order to study the influence of magnetic field on the corrosion and polarization behavior of marine magnesium alloys in seawater, the potentiostatic polarization test and kinetic potential polarization test were used to study the current density and self-corrosion potential of AZ31B in simulated seawater. The results show that the magnetic field can change the self-corrosion state of AZ31B magnesium alloy, reduce the current density, improve the corrosion resistance of the material.
