Description

一种铝棒与具有中间过渡层的钢棒连续驱动摩擦焊接方法
技术领域
一种铝棒与具有中间过渡层的钢棒连续驱动摩擦焊接方法,属于焊接技术领域,尤其涉及铝棒与钢棒的摩擦焊接。
背景技术
铝/钢复合结构兼具铝的比强高、导电导热性好、耐腐蚀性好和钢的高强度、抗蠕变性能良好等优点,可满足众多特殊使用要求;然而不论是使用熔化焊、熔钎焊还是固相连接方法来焊接铝钢异种金属,脆硬的FexAly金属间化合物的形成都是不可避免的。连续驱动摩擦焊作为一种高质、高效、环保的固相焊方法,在焊接异种金属时能够有效地减少金属间化合物的生成,具有显著优势。
当这两种材料相互连接时,冶金问题是不可避免的,由于铁在铝中的溶解度为零,往往会在铝上产生氧化膜以及可能形成低塑性脆性金属间化合物(如FeAl3、Fe2Al5),其厚度、分布形式与成份比例会显著影响接头机械性能,如果其生成量过多则会严重降低接头力学性能:此外,热胀系数、熔点、导电率和比热等热性能的差异会导致熔焊后产生内应力,这也将影响接头的力学性能。因此,如何抑制铝上的氧化膜以及低塑性脆性金属间化合物的生长,一直是铝/钢连接的两个主要问题。
发明内容
本发明的目的在于:提供一种铝棒与具有中间过渡层的钢棒连续驱动摩擦焊接方法,通过在钢棒的待焊端面电镀一层银形成中间过渡层,有效地抑制了Fe向Al的扩散过程,一定程度地阻止了富“铝”相金属间化合物的形成,同时可以降低摩擦系数进而降低产热,避免界面过热生成较厚的金属间化合物层,使得到的接头具有更好的强度和韧性。
本发明采用的技术方案如下:
为实现上述目的,本发明提供一种铝棒与具有中间过渡层的钢棒连续驱动摩擦焊接方法,包括以下步骤:
(1)将待焊接的铝棒和钢棒端面进行切铣,使端面光滑;
(2)在钢棒的待焊端面上电镀一层银形成中间过渡层;
(3)清洗铝棒与钢棒的待焊端面,将铝棒和钢棒分别用旋转夹具和移动夹具固定,并保证铝棒与钢棒处于同一轴线上;
(4)打开冷却系统,开启焊接,焊接完成后,经冷却后将焊件取下。
作为优选,所述步骤(2)中,所述中间过渡层的厚度范围为6~30μm。
作为优选,所述步骤(2)中,镀银包括三个步骤:
(1)电净:电净电压为10~12V,时间为30~60s,工件接负极;
(2)活化:电净电压为10~12V,时间为30~60s,工件接负极;
(3)电镀:电镀电压为2~3V,时间为60~300s,工件接负极,镀后用去离子水清洗,快速吹干。
作为优选,所述步骤(3)中,清洗待焊端面是采用无水乙醇和丙酮来清洗铝棒与钢棒的待焊端面。
作为优选,所述步骤(4)中,焊接过程包含摩擦加热和顶锻两部分。
作为优选,所述步骤(4)中,焊接过程的工艺参数为:主电机转速800~1500r/min、摩擦压力20~80Mpa、摩擦时间0~2s、顶锻压力30~100Mpa、顶锻时间0~3s。
综上所述,由于采用了上述技术方案,本发明的有益效果是:
本发明在钢棒的待焊端面电镀一层银形成中间过渡层,中间过渡层的存在有效地抑制了Fe向Al的扩散过程,一定程度地阻止了富“铝”相金属间化合物的形成;另一方面由于银的强度低塑性好,在摩擦阶段可以降低摩擦系数进而降低产热,避免界面过热生成较厚的金属间化合物层,使得到的接头具有更好的强度和韧性,提高接头的力学性能。
