摘要:
概述了国内外难熔金属表面高温抗氧化涂层的研制现状。涂层主要分为5大体系，其中硅化物涂层是应用最为广泛的涂层体系，高温氧化环境下硅化物能够生成玻璃态SiO2，有效阻挡氧向内部扩散，起到防护作用。贵金属体系是抗氧化性能更为优越的材料体系，其中Re/Ir是目前性能最高的高温抗氧化材料，Ir涂层的致密性及厚度是决定其抗氧化寿命的主要因素。国内目前已形成自1 200 ℃至2 000 ℃应用的一代铌铪合金涂覆硅化物涂层、二代铌钨合金涂覆硅化物涂层、三代铼基材涂覆铱涂层共三代材料体系，其中一代广泛应用于卫星、飞船等多种型号产品，二代应用于卫星并于2012年5月首飞成功。目前国内致力于Re/Ir材料体系的工程化应用研究，已进行短喷管试车，试车温度高达2 090 ℃，累计时间300 s，涂层未失效。
Abstract:
The overview is about the development and trend of high temperature oxidation resistance coatings on refractory metals. Silicide coatings on Nb alloy have been using widely, as glass phase SiO2 is formed at high temperature oxidation environment. Re/Ir is considered as best material of high temperature oxidation resistance, and the life of Ir coating is affected by thickness and compactness. In China, three generations materials used for 1 200~2 000 ℃have been developed, including 1st generation NbHf alloy using silicide coating, 2nd generation NbW alloy using silicide coating and 3rd generation Re using Ir coating. The 1st and 2st have been used to satellite and airships. Now engineering application study of the Re/Irmaterial is proceeding. Short nozzle of Re/Ir has been tested, and the temperature of combustion chamber wall reached 2 090 ℃,for 300 s without failure.
