Description
技术领域
本发明涉及一种陶瓷劈刀材料及其制备方法,具体涉及一种用于焊接的陶瓷劈刀材料及其制备方法。
背景技术
现有的用于焊接的劈刀材料一般都为ZTA材料氧化锆增韧氧化铝陶瓷,在氧化铝中掺杂了氧化锆,使得材料的微观结构均匀而致密,使用该材料制成的劈刀具有较好的抗化学腐蚀性和耐磨性。
但是使用ZTA材料制作的陶瓷劈刀,硬度相对较小,密度相对较小,材料孔隙率较大,当使用铜作为焊线时,由于铜的硬度比较大,在焊接时需要使用较大的超声波能量,而在焊接时劈刀端面会受到较大的剪切应力,结晶粒子较易脱落,增大劈刀端面的磨损程度,从而缩短其使用寿命。
发明内容
本发明的目的在于克服现有技术存在的不足之处而提供一种硬度高、密度大、平均粒径小、气孔率小的陶瓷劈刀材料及其制备方法。
为实现上述目的,本发明采取的技术方案为:一种陶瓷劈刀材料,包含以下重量百分含量的组分:
基体陶瓷65~92.99%,辅助陶瓷0.1~30%,添加剂0.1~30%;
其中,基体陶瓷为氧化铝、氧化锆中的至少一种;辅助陶瓷为氧化锆、氧化铬、氧化铒、五氧化二铌、氧化锌、氧化铁、氧化钛、氧化钙、氧化镁、碳化硅、氧化锶、氧化钡、氮化硅和碳化钨中的至少一种。
基体陶瓷在陶瓷劈刀材料中重量百分含量为65~92.99%时,烧结后的晶相较致密,得到的材料硬度和断裂韧性较好。当基体陶瓷的含量高于92.99%时,不利于烧结体晶粒大小的控制,烧结后的晶相相对来说不致密,而且最终得到的材料硬度和断裂韧性都较差。辅助陶瓷具有促进烧结的作用。氧化锆和碳化硅可以增加材料的韧性;氧化铬、氧化锌、氮化硅、碳化钨、氧化钡等可以使材料晶相更致密,使材料更耐磨。
作为本发明所述陶瓷劈刀材料的优选实施方式,包含以下重量百分含量的组分:所述基体陶瓷75~90%,辅助陶瓷6~23%,添加剂2~4%。
当陶瓷劈刀材料采用上述重量百分含量组分时,基体陶瓷材料可以保证材料本身的高硬度、耐磨耐腐蚀性等性能,辅助陶瓷可以促进材料烧结,使得烧结后的平均粒径较小,晶相致密,材料更耐磨,硬度和使用寿命等都能到达到最佳效果。
作为本发明所述陶瓷劈刀材料的优选实施方式,所述基体陶瓷为氧化铝或者氧化铝与氧化锆的混合物,在氧化铝与氧化锆的混合物中,氧化铝和氧化锆的质量比为15~18:2~5。
相对于氧化铝,氧化锆的断裂韧性更强,不易产生开裂,更耐强碱腐蚀。而氧化铝和氧化锆的组合,相对于单独使用氧化铝来说,材料的韧性更强,不易产生开裂,对单独使用氧化锆来说,材料的硬度更高,更耐磨。尤其是,当基体陶瓷中氧化铝和氧化锆的质量比为15~18:2~5时,材料的韧性更强、硬度更高、耐磨性更强。
作为本发明所述陶瓷劈刀材料的优选实施方式,所述辅助陶瓷为氧化锆、氧化铬、氧化铒、五氧化二铌、氧化锌、氧化铁、碳化硅、氮化硅和碳化钨中的至少一种;优选地,所述辅助陶瓷为氧化锆、碳化硅、氧化铬、氧化锌、氮化硅和碳化钨中的至少一种。当辅助陶瓷为氧化锆、碳化硅、氧化铬、氧化锌、氮化硅和碳化钨中的至少一种时,所得材料的韧性的更强、硬度更高、耐磨性更强。
作为本发明所述陶瓷劈刀材料的优选实施方式,所述添加剂为粘结剂、增塑剂和分散剂中的至少一种;
作为本发明所述陶瓷劈刀材料的优选实施方式,粘结剂为聚氯乙烯、聚乙烯醇、聚乙烯缩丁醛、丙烯酸树脂、甲基纤维素、乙基纤维素、硝化纤维酯、聚氨酯树脂和酚醛树脂中的至少一种;
增塑剂为柠檬酸酯、二辛酯和聚乙二醇中的至少一种;
分散剂为卵磷脂、磷酸酯类分散剂、聚乙二醇、聚甲基丙烯酸甲酯和鱼油中的至少一种。
另外,本发明的另一目的在于提供了一种采用上述陶瓷劈刀材料制备而成的陶瓷劈刀。
采用本发明所述陶瓷劈刀材料制备而成的陶瓷劈刀硬度较高,密度较大,平均粒径小,韧性好,使用过程中其结晶粒子不易脱落,具有出色的耐磨性能。
本发明的再一目的在于提供了一种工艺简单、便于实现的上述所述陶瓷劈刀材料的制备方法,为实现此目的,本发明采取的技术方案为:一种陶瓷劈刀材料的制备方法,包括以下步骤:
