Method for preparing steel-aluminum pipe joint through combination of interface plating and corrugated hot pressing

The invention discloses a method for preparing a steel-aluminum pipe joint through combination of interface coating and corrugated hot pressing, and belongs to the technical field of metal layered composite material preparation. Comprising the following steps that a corrugated seamless steel pipe and a corrugated aluminum pipe are immersed in molten aluminum, then the corrugated face of the seamless steel pipe and the to-be-compounded face of the seamless aluminum pipe are subjected to pressure assembly, heat treatment, cooling and machining, and the steel-aluminum pipe joint prepared through combination of the interface coating and corrugated hot pressing is obtained. The steel-aluminum pipe joint prepared by the method provided by the invention is high in interface bonding strength. 本发明公开了一种界面镀层与波纹热压联合制备钢-铝管接头的方法，属于金属层状复合材料制备技术领域。包括以下步骤：将具有波纹状的无缝钢管和无缝铝管分别浸入熔融态铝液中，然后将无缝钢管的波纹状面与无缝铝管的待复合面通过压力组装，热处理，冷却，机械加工，即得到界面镀层与波纹热压联合制备钢-铝管接头。利用本发明提供的方法制备的钢-铝管接头界面结合强度高。
