Description

高强度耐腐蚀铝合金型材
技术领域
本发明涉及铝合金型材技术领域，具体为一种高强度耐腐蚀铝合金型材。
背景技术
铝合金型材有很多优异的物理化学性能，被广泛应用到国民经济的各个领域。铝合金的表面暴露在大气中时，会在其表面覆盖一层很薄的自然氧化膜，但是由于其表面的自然氧化膜很容易被腐蚀，从而大大降低了铝合金材料的使用寿命。因此，通常会对铝合金型材进行表面处理，增加其耐腐蚀性，现有的铝合金型材表面处理工艺有阳极氧化、电解着色、电泳涂漆、粉末喷涂、氟碳漆喷涂、拉丝等，这些表面处理工艺均起到一定的耐腐蚀效果，然而这次处理方式仅仅是增加了铝合金型材的耐腐蚀效果，而随着铝合金型材使用的时间延长，耐腐蚀效果逐渐降低，酸碱性溶液附着在其表面，依然会对铝合金型材造成腐蚀，因此，需要一种耐腐蚀性非常优异的铝合金型材来满足人们的高使用需求。
发明内容
为了解决上述问题，本发明提供了高强度耐腐蚀铝合金型材。
本发明是通过以下技术方案实现的：
一种高强度耐腐蚀铝合金型材，包括铝合金基体和覆盖在其表面的防腐涂层，所述防腐涂层按重量份数包括10-20份碳化硅、10-20份三氧化二铬、 15-20份氧化镍、10-19份碳化铬、18-28份氧化铝、8-10份氮化硅以及10-15 份聚四氟乙烯粉末。
所述聚四氟乙烯粉末的粒径为40-60nm。
所述防腐涂层按重量份数包括15份碳化硅、15份三氧化二铬、16份氧化镍、14份碳化铬、20份氧化铝、9份氮化硅以及11份聚四氟乙烯粉末。
所述防腐涂层通过等离子熔覆处理覆盖在铝合金基体的表面。
与现有技术相比，本发明的有益效果是：
本发明在防腐涂层的内部加入疏水性的聚四氟乙烯粉末，得到疏水型防腐涂料，酸碱性溶液不易附着在铝合金型材表面，减少了酸碱性腐蚀溶液与铝合金型材的接触时间，有效提升了铝合金型材的耐腐蚀性，性能更佳。
具体实施方式
下面对本发明进一步说明：
一种高强度耐腐蚀铝合金型材，包括铝合金基体和覆盖在其表面的防腐涂层，所述防腐涂层按重量份数包括10-20份碳化硅、10-20份三氧化二铬、 15-20份氧化镍、10-19份碳化铬、18-28份氧化铝、8-10份氮化硅以及10-15 份聚四氟乙烯粉末。
所述聚四氟乙烯粉末的粒径为40-60nm。
所述防腐涂层按重量份数包括15份碳化硅、15份三氧化二铬、16份氧化镍、14份碳化铬、20份氧化铝、9份氮化硅以及11份聚四氟乙烯粉末。
所述防腐涂层通过等离子熔覆处理覆盖在铝合金基体的表面。
实施例1
一种高强度耐腐蚀铝合金型材，包括铝合金基体和覆盖在其表面的防腐涂层，所述防腐涂层按重量份数包括15份碳化硅、15份三氧化二铬、16份氧化镍、14份碳化铬、20份氧化铝、9份氮化硅以及11份聚四氟乙烯粉末，防腐涂层通过等离子熔覆处理覆盖在铝合金基体的表面，形成疏水型防腐涂层，其中聚四氟乙烯粉末的粒径为40nm。
本实施例中，陶瓷防腐涂料通过等离子熔覆处理均匀覆盖在铝合金的表面，起到全面防腐作用，能够避免酸碱液体对铝合金表面造成的腐蚀，防腐涂料中增加纳米聚四氟乙烯粉末，聚四氟乙烯具有疏水性，避免酸碱液体长时间附着在铝合金表面，大大降低了铝合金被腐蚀的几率，延长了其使用寿命。
