摘 要: 为了获得较高的界面结合强度,对20号钢表面采用热浸镀锡处理后,进行液固扩散连接,制备ZChSnSb11-6/20号钢双金属复合材料。采用扫描电子显微镜(SEM),X射线衍射仪(XRD)表征了ZChSnSb11-6/20号钢结合过渡区的形貌及其元素分布,并对其硬度和界面结合强度进行检测。结果表明:通过20号钢热浸镀锡后,再进一步进行液固扩散可以制备结合面均匀稳定的ZChSnSb11-6/20号钢双金属复合材料,20号钢中Fe与Sn形成一层互扩散组织的结合过渡层,实现了20号钢与巴氏合金ZChSnSb11-6的冶金结合;结合过渡区的硬度明显高于两侧基体的,界面结合强度可达60.15MPa。

Abstract:In order to higher bonding strength, ZChSnSb11-6/20 steel bimetal composite material was prepared by means of diffusion bonding after hot dipping tin plating in the 20 steel surface. The transition zone morphology and element distribution of ZChSnSb11-6/20 steel bimetallic material were characterized by scanning electron microscopy (SEM) and X-ray diffractometer (XRD). Also, the hardness and interface bonding strength were tested. The results show the functionality and availability of the method using the hot dipping tin to attach the ZChSnSb11-6 with 20 steel. There is a bonding transition zone generated by the diffusion between the steel substrate and tin, which achieves close combination of the steel and Babbitt. Besides, the hardness of transition zone is significantly higher than that of both sides of the substrate, and the bonding strength reaches up to 60.15 MPa.
