渗铝钢合金层/基体界面的生长模型研究

Interfacial growing model between alloy layer and matrix of aluminized steel

从钢的热浸镀铝钢扩散特点出发,根据金属间化合物新相晶核形成理论,建立了界面金属间化合物的生长行为模型。经试验验证,该模型能比较准确地计算扩散过程中界面金属间化合物相的生长厚度。

Starting from the diffusion characteristic of the aluminized layer in the diffusion process of hot dip aluminized steel,in accordance with the crystal nucleus forming theory of intermetallic compound new phase,the growing model of the interfacial intermetallic compounds between alloy layer and steel matrix of hot dip aluminized steel was established.The experimental results show that the growing model can comparatively accurately calculate the intermetallic compound growth thickness of the interface between alloy layer and steel matrix.
