国家知识产权局公开信息显示，云南云铝泽鑫铝业有限公司于 2024 年 12 月申请的 “一种电解法制备铝合金的方法” 专利（公开号：CN119640338A），近日引发行业关注。该专利针对传统电解法中合金元素弥散不均、材料性能受限的难题，提出了一种优化的制备工艺，为铝合金材料的性能提升提供了新的技术路径。

根据专利内容，该方法通过三个关键步骤实现技术突破：首先，以铝土矿为原料提取铝氧化物；其次，将铝氧化物与熔融氯化盐混合加热，并在特定温度区间内加入掺杂合金元素及表面活性剂，通过控制电流密度和电解时间进行电解；最后对电解产物进行机加工成型。其中，熔融氯化盐的用量占比及表面活性剂的选择与添加量被精确调控，例如选用皂苷、卵磷脂等表面活性剂，其用量根据类型在铝氧化物质量的 0.05%-3% 范围内优化。这种工艺设计有效改善了铝离子的沉积过程，使掺杂合金元素在铝液中的分散更加均匀，从而提升了铝合金材料的稳定性和长效性能。

该专利的创新之处在于通过工艺参数的精准控制和表面活性剂的引入，解决了传统电解法中合金元素弥散度低的技术瓶颈。这一突破不仅有助于提高铝合金产品的综合性能，还为高端铝合金材料的定制化生产提供了更高效的技术方案，有望推动铝加工行业在航空航天、汽车制造等对材料性能要求严苛的领域实现新的应用突破。云南云铝泽鑫铝业此次专利的申请，体现了企业在电解铝合金技术领域的创新实力，也为行业内提升材料制备水平提供了重要的技术参考。
