摘要

研究了碳钢表面处理和预热温度对ZL109与Q235液-固复合界面组织和性能的影响。结果表明

对Q235钢基底进行表面处理可以有效地改善ZL109铝合金在Q235钢基底表面的润湿性;镀Ni-Cu复合镀层可以很明显地改善铝钢液-固结合中的润湿性并防止二次氧化的产生。通过该工艺复合的Q235/ZL109复合界面为冶金结合

界面组织为FeAl3、Fe2Al5金属间化合物

并能将复合界面结合层厚度控制在15～28μm之间

显著提高复合界面的剪切强度。

Abstract

Effects of carbon steel surface treatment and pre-heating temperature on solid-liquid compound interface structure and performance of the Q235 / ZL109 were investigated. The results show that the surface wettability of ZL109/Q235 can be effectively improved by the surface treatment on the Q235 steel substrate. The Ni-Cu plating surface treatment can significantly improve the wettability of the bi-metallic samples and prevent from the secondary oxidation. The compound interface of the Q235 （700 ℃）/ZL109 （730 ℃） exhibits metallurgical bonding

which is composed of FeAl3

Fe2Al5 intermetallic compounds

and the thickness of bonding layer can be controlled in range of 15 μm to 28 μm

significantly improving the shear strength of compound interface.
