有色金属材料的工业用途在电气和化学工程应用中具有重要意义。由于铜-铝接头具有较高的导电性、导热性、耐腐蚀性和机械性能等独特性能，因此在某些应用中不可避免地要使用铜-铝接头。摩擦焊接是最常用的方法，由于材料和能源的节省。在本研究中，铜和铝材料的摩擦焊接连接。使用统计方法获得最佳参数。对接头进行了拉伸和显微硬度测试。显微镜和宏观照片进行了检查。能量色散X射线分析用于确定焊接过程中发生的相。在焊接部件的断裂表面观察到灰色层。据认为，该层降低了接头的强度。
Industrial use of non-ferrous materials is significant in the electrical and the chemical engineering applications. Copper–aluminium joints are inevitable for certain applications due to unique performances such as higher electric conductivity, heat conductivity, corrosion resistance and mechanical properties. Friction welding is the most common method used due to material and energy saving. In the present study, copper and aluminium materials were joined by friction welding. Optimum parameters were obtained using a statistical approach. Tensile and microhardness tests were applied to the joints. Micro- and macrophotographs were examined. Energy dispersive X-ray analysis was used to determine the phases that occurred during welding. A grey layer was observed at the fracture surfaces of welded parts. It was considered that this layer decreased the strength of the joints.
