摘　　要：以Ｆｅ和ＦｅＢ为例，分别通过对与锌互溶和不互溶两类材料的锌蚀行为进行研究，限定了传统液态金属腐蚀机制的适用范围并对与锌不互溶材料提出了新的腐蚀机制。传统的腐蚀机制只适合与锌互溶的材料，而与锌不互溶材料在锌液中的腐蚀，主要为表面缺陷所致。新机制的提出为研制出高寿命的耐锌蚀材料提供了有效的理论依据。The zinc corrosion of two kinds of materials, soluble and insoluble in liquid zinc, such as Fe and FeB are separately dealt with in this paper. Traditional corrosion theory on liquid metal corrosion is defined for soluble materials. A new corrosion theory is proposed for insoluble materials. In this new theory defects on the surface of the insoluble materials are assumed as the main reasons for corrosion, which provides a theoretically practical basis for fabricating new materials with good corrosion resistance to liquid zinc.
