With the rapid development of the global economy and the extensive use of land resource,exploitation of ocean energy has been more and more attention. The harsh environment of the ocean put forward higher requirements to the equipment and materials. Faced with this complex environment,the characteristics of bimetallic composite materials have a huge advantage. The composite-material which consist of carbon steel,brazing layer and stainless steel was investigated in order to reveal the change on the bonding strength of the binding layer after rolling. Then, the change on microstructure which was in the vicinity of the weld was analyzed by metallurgical microscope. The tensile fracture of interface before and after rolling was also characterized by scanning electron microscope to analyze the its bonding strength. Finally,we could come some expectant conclusions.%随着全球经济的飞速发展和对陆地资源的大量使用，更深更远的海洋中的能源开采受到了越来越多的重视，而海洋的苛刻环境就对设备材料提出了更高的要求。面对这种复杂的环境时，双金属复合材料的特性就有了巨大的优势。本文针对在碳钢表面预镀镍钼磷合金钎料制备出的碳钢+中间钎焊层+外层不锈钢的复合材料，研究经过轧制处理后其结合层结合强度的变化，利用金相显微镜分析焊缝附近组织的变化，扫描电子显微镜分析拉伸断口以此来对轧制前后结合强度进行分析。
