通过T4和T6处理对镁锌合金中的第二相进行了调整，研究了第二相在镁锌合金腐蚀行为中的作用。第二相的尺寸只有几百纳米。它们在接收到的样品的边界上呈现离散分布，在T6样品中呈现连续分布。不含第二相的T4样品的耐蚀性最好，而第二相体积分数最大的T6样品的耐蚀性最差，这主要是由于第二相的微阴极效应所致。(C)2012爱思唯尔有限公司。保留所有权利。
The MgxZny second phases in Mg-5Zn alloy were adjusted by T4 and T6 treatment, and then the role of second phases in the corrosion behavior of Mg-5Zn alloy was investigated. The dimension of the MgxZny second phases is only some hundred nanometers. They present discrete distribution on the boundaries of the as-received sample and continuous distribution in the T6 sample. The T4 sample in absence of second phases exhibits the best corrosion resistance while the T6 sample with the largest volume fraction of second phases exhibits the worst one, which can be attributed to the micro-cathodic effect of second phases.
