摘要
制导火箭在论证设计时须充分考虑在不同海拔尤其在高原条件下的作战需求,且弹箭尾翼的气动热防护非常重要。等离子喷涂是借助某种热源使材料表面获得各种功能涂层的有效方法,而等离子体微弧氧化是一种直接在有色金属表面原位生长陶瓷膜的新技术。从工程应用的角度出发,研究了钢和铝合金材质尾翼的不同热防护机理、涂层制备方法、工艺特点和性能测试方法,并对这两种应用予以展望。
When guided rocket is designed,the operational requirement in different altitudes,especially at high altitude condition,is supposed to be considered properly.Aero-dynamic heat protection of rocket wing becomes increasingly important.Plasma spray is an effective method to obtain various functional coatings on the surface of the material by means of a heat source,and plasma microarc oxidation is a new technique for in-situ growth of ceramic coatings on the surface of nonferrous metals.From the view point of engineering application,the different thermal protection mechanism of the steel and aluminum alloy tails,the methods of preparing functional coating,the process features and performance test methods,have been studied in this article,and the two applications are prospected.
