Abstract

The invention belongs to the technical field of metal composite sheet strips, and particularly relates to a method for preparing a metal composite sheet strip through electroplating deposition and rolling. The method comprises the following steps of 1, surface treatment, 2, laminating, 3, electroplating deposition, 4, blank manufacturing, 5, rolling, 6, thermal treatment, and 7, finishing. Electroplating deposition is combined with a traditional rolling process, a to-be-compounded surface of a metal sheet strip base material is deposited with a clad layer, one part of the deposited clad layeron the surface of the base material generates a hooking effect and a riveting effect with base material metals, the other part of the clad layer and an contact interface between the base material metals generate diffusion, the clad layer generating the hooking effect and the riveting effect with the base material metals prompts the coplastic deformation of the special-shaped metal sheet strips andthe clad layer under the action of a rolling force, the action area of the shearing force of the surfaces of the metals is remarkably increased, the numerical value is increased, the shearing actionof the metals is enhanced, the fracture of the interface between the metals is accelerated, the metallurgical welding is prompted, and the comprehensive mechanical performance is further improved through the combination with the post heat treatment.

Description

technical field [0001] 本发明属于金属复合板带制备技术领域,具体涉及一种电镀沉积辅助轧制金属复合板带的方法。 Background technique [0002] 金属复合材料通过将不同金属在物理、化学等作用下复合,可以充分发挥各组元材料的优势,使产品获得耐腐蚀、轻质、比强度高、减震降噪等优异的综合性能,广泛应用于航空航天、军事装备、石油化工等重大领域。 [0003] 金属复合材料主要包括层状复合材料、颗粒增强材料、纤维增强材料等,其制备方法包括轧制复合法、扩散焊接法、爆炸复合法、铸轧复合法、挤压拉拔法等。根据复合材料在成型时物态的不同,现阶段层状复合材料的加工方法可分为液-液相复合法、液-固相复合法和固-固相复合法,不同的加工方法其各自具有优势和局限性。 [0004] 液-液相复合法主要是电磁连铸复合,主要用于生产不锈钢-碳钢复合材料,目前仍处于研究阶段,复合板材的组织和性能相对轧制复合法差。 [0005] 固-液相复合法主要包括浇铸\铸轧复合、喷射沉积法、反向凝固法等。浇铸\铸轧在生产时复合温度高,复合基板表面易氧化,复层金属和基体金属熔点差异大容易造成结合部位熔损,界面结合效果差。喷射沉积法和反向凝固法都是在基板上复合一层凝固层,复合层的厚度受限,仅适用于提高基板表面耐腐蚀、耐磨、耐高温等性能。 [0006] 固-固相复合法种类众多,主要包括爆炸复合、轧制复合、扩散焊接等。爆炸复合是借助炸药爆炸产生的高强化学能驱动覆板高速碰撞基板,破坏金属表面氧化层,促进复合板的塑形变形、熔化、扩散,实现金属焊接,适用于熔点相差悬殊、热膨胀悬殊、硬度差异大的金属焊合,避免金属间化合物的生成,结合强度较高,但产量、生产率、成材率都比较低,产品质量稳定性差,具有巨大的安全隐患、噪声污染和环境危害。扩散焊接是将表面清洁的组元金属叠放在一起,加热加压后通过界面原子间相互扩散使金属结合可分为无助剂和有助剂扩散焊接,该方法需要长时间加热加压,结合强度较低,不适用于大尺寸复合板带的工业化生产。 [0007] 轧制复合方法的基本原理是在轧制力的作用下,使得两种或两种以上的金属材料同时产生塑性变形,表面金属层破裂、裸露出新鲜金属,进而使板面之间形成冶金结合,通过后续的热处理,进一步提升结合强度;其生产成本低,工艺简单,...
