Description
技术领域
本发明涉及一种核壳结构金属氧化物增强银基材料的方法,属于电子信息新材料领域。
背景技术
银基电触头材料具有良好的抗熔焊性,优良的导热导电性能,所以低压电器开关中的触头材料大多会选用银基复合材料为主。根据第二相的种类可以将银基电触头分为纯金属弥散强化相Ag/纯金属电触头材料;以石墨作为弥散强化相的Ag/C电触头材料;以氧化物为弥散强化相的Ag/MeO电触头材料。其中研究最为广泛的就是以氧化物为弥散强化相的Ag/MeO电触头材料。
关于金属氧化物复合材料制备工艺,研究人员相继开发化学镀、化学共沉淀法、溶胶-凝胶法、高能球磨等新型金属氧化物材料制备工艺为了解决传统制备工艺的不足。但是新型的方法并不能实际解决相应的问题,主要原因在所获得的银基电触头材料的综合性无法媲美传统电触头材料Ag/CdO的优异性能。
发明内容
本发明的目的在于提供一种核壳结构金属氧化物增强银基材料的方法,能够通过壳CuO与银具有良好界面润湿性的特点,改善了ZnO增强银基复合材料界面润湿性,提高了银基复合材料的加工性能与成材率;所获得的ZnO@In2O3CuO增强银基复合材料具有优异的力学性能,具体包括以下步骤:
(1)将纳米ZnO粉与铟粉、铜粉按ZnO粉与InCu粉质量比为12:(0.5-3.5)或10:(2.5-4.5)的比例混合,在惰性氩气保护下,以转速为450-550r/min球磨0.5-2h,获得ZnO@InCu粉体。
(2)将步骤(1)中的ZnO@InCu粉体与银粉、氧化银粉按照在银基体中生成质量百分比为13%-16%的ZnO@In2O3CuO为准来配制,并以转速为100-500r/min球磨0.5-2h获得混料均匀的复合粉体。
(3)将步骤(2)中的复合粉体装入模具中,以150-500MPa压制压力条件下成形,并将成形锭坯放入原位反应烧结炉中,在100-850℃条件下烧结发生原位反应,获得ZnO@In2O3CuO增强银基复合材料烧结坯;最后对该烧结坯进行致密化、挤压轧制制备成带材。
优选的,本发明所述市售的纳米ZnO粉的粒度为30~70nm,纯度为99.9%;铜粉、铟粉粒度为0.5-50μm,纯度为99.9%;银粉粒度为10-80μm,纯度为99.9%;氧化银粉粒度为10-50μm,纯度为99.9%。
优选的,本发明步骤(1)中铟粉、铜粉质量比为1:1。
优选的,本发明步骤(3)中压制成型的条件为:在300-400MPa压制压力条件下成形。
优选的,本发明步骤(3)中烧结条件为100℃保温1h,然后升温到300℃保温1h,然后升温到830℃保温1h。
本发明的原理在于:利用金属(In、Cu)硬度低于陶瓷(ZnO),且金属在球磨过程中会发生焊合的机理,通过球磨得到ZnO@InCu核壳结构的粉体(核是ZnO,壳是InCu合金);再通过原位反应合成中InCu与Ag2O反应获得In2O3CuO和Ag,从而得到ZnO@In2O3CuO核壳结构增强银基复合材料;这种核壳结构的主要优点在于:既可以通In2O3、CuO与银界面润湿角低于ZnO与银界面润湿角,改善增强相与银的界面润湿性,使得增强相与银的界面结合牢固,从而提高复合材料的力学性能;又可以将ZnO与In2O3CuO组成整体的氧化物增强相,能够保证氧化物在银基体中分布的均匀性,有利于在加工过程中,充分发挥整体氧化物对位错的阻碍作用,从而提高复合材料的力学性能;也有利于ZnO@In2O3CuO核壳结构增强银基复合材料在电接触应用过程中的电侵蚀稳定性。
本发明的有益效果:
与传统银金属氧化物相比,获得了一种核壳结构的金属氧化物增强银基复合材料;与AgZnO复合材料相比,该复合材料既改善ZnO与银的界面润湿性,提高了复合材料的加工性能,又获得了力学性能优异的ZnO@In2O3CuO核壳结构增强银基复合材料。
