Description
技术领域
本发明涉及一种合金钎料以及该钎料的制备方法,属于材料加工技术领域。
背景技术
钎料是指为实现两种材料或部件的结合,在其间隙内或间隙旁所加的填充物。钎料的熔点必须比焊接的材料熔点低。可用于连接精密、复杂、多铤缝和异类材料的焊接。钎料按熔点高低分为软钎料(熔点低于450℃的钎料)和硬钎料(熔点高于450℃的钎料)。
目前,现有镁合金钎料及其制备中存在成本高、熔点高、工艺性能差等缺点,不佳等问题。
发明内容
本发明针对现有技术存在的缺陷,提供一种钎料合金,该钎料合金铺展性好,焊性能好。
本发明的另一目的是提供上述钎料合金的制备方法,该方法工艺简单,适于工业化大批量生产。
本发明的目的是通过以下措施实现的:
一种钎料合金,其合金成分的质量百分含量为:55%Mg,0.8% Al,2%Sn,0.002%Be,0.002%Te,0.3%La,5%Bi,其余为Zn。
其制备过程如下:
首先按照质量百分含量为55%Mg,0.8% Al,2%Sn,0.002%Be,0.002%Te,0.3%La,5%Bi,其余为Zn进行配料,将上述配好的放在SF6保护气氛的电炉坩埚中一起加热熔化,当温度升至680℃时,保温10分钟后浇注到预热到200℃的钢锭模中冷却,便得到钎料合金。
本发明相比现有技术具有如下有益效果:
本发明的镁基钎料合金,原料易得,制备工艺简单,钎料合金性能良好。
合金中各元素主要起到以下几方面的作用:
本发明钎料合金中,Bi、Te和Sn本身的熔点均较低,加入它们可降低钎料合金的熔点。
成份中Bi能够很好提高钎料的润湿性,还能更加有效改善了材料的铺展性。
本发明中钎料合金的成份与被焊镁合金成份接近,可提高被焊合金焊点的剪切强度。
具体实施方式
实施例一:
各成份重量百分含量按55%Mg,0.8% Al,2%Sn,0.002%Be,0.002%Te,0.3%La,5%Bi,其余为Zn进行配料。其中原料中取纯Al锭,纯Mg锭,纯Sn条,纯Be块,纯Te锭纯Bi粉, g纯Zn条,Mg-La中间合金块(其中La的质量百分含量为15%),放在SF6保护气氛的电炉坩埚中,加热熔化,当温度升至680℃时,保温10分钟后浇注到预热到200℃的钢锭模中冷却,便得到钎料合金。
实验数据:
下表为本发明制得的镁基钎料合金的指标参数,具体如下:
材料 | 剪切强度(Mpa) | 铺展面积(mm2) | 钎焊工作温度(℃) |
如实施例一制得的材料 | 70 | 182 | 395-405 |
