Description
技术领域
本发明涉及航空发动机隐身材料涂层技术领域,属于一种陶瓷微球包覆铁钴镍钐钕高熵涂层及其制备方法。
背景技术
隐身技术起源于第二次世界大战,在美英德日俄等发达国家受到了广泛的关注。由于雷达探测具有探测距离远精度高等优点,对现代兵器产生的威胁日益严重,为此各国都在努力发展雷达隐身技术。雷达隐身技术是通过减弱抑制偏转目标的雷达回波强度或减小雷达散射截面积(RSC),来降低敌方雷达对目标的发现概率,主要包括外形隐身技术和雷达吸波材料隐身技术,其中雷达吸波材料隐身技术因其匹配性强,操作方便,易于调节等特点已成为了必要的隐身措施。
吸波涂料一般由胶黏剂、吸收剂和各种助剂组成,其中吸收剂是主体材料,直接决定了涂层吸波性能。根据吸波原理可知,影响吸波材料性能的重要因素包括吸收材料的阻抗匹配特性及材料衰减特性。其中,提高电磁波衰减需要提高的吸波材料的电磁损耗特性,而吸波材料的阻抗匹配需要吸波材料具有较好的介电匹配特性。但由于单一吸收剂存在频带窄、吸波性能不稳定等缺点,单一吸收剂的吸波材料离预期目标有一定差距。因此,吸收剂表面改性研究受到了广泛的关注。表面改性是一种具有特色的吸收剂改性方法,广泛应用于吸收剂表面处理,不仅可以改善吸波材料的抗氧化性和抗腐蚀性,而且可以降低介电常数和改善阻抗匹配等特性,最终达到提高吸波材料的吸波性能目的。
