摘要
航天领域热处理工艺技术的研究与应用是热处理技术应用的重要部分,是航天型号产品研制的特殊过程和关键工序,关系着航天产品的服役性能,本文根据航天科技集团公司热处理工艺技术现状,从航天铝合金、超高强度钢、磁性合金等材料构件热处理、耐磨构件表层硬化热处理等方面,论述目前航天领域热处理工艺研究进展、应用现状及发展趋势。航天飞行器迫切的减重需求、不断提高的服役要求,使得以铝合金为代表的轻质结构材料成为研究热点,并在超高强度钢大长径比、变壁厚薄壁零件热处理数值模拟应用方面取得进展,离子渗氮、低压渗碳、离子注入等多项先进表层硬化技术也不断获得应用。
The heat treatment technology for aerospace materials and componentsis an important part of the research and application of heat treatment technology,and is the special process and key procedure for developing the space model products. It has a significant impact on the service performanceof aerospace products. According to the situation of heat treatment technology in China aerospace science and technology corporation,the research progress and application situation and development trend are discussed from the heat treatment of aerospace aluminum alloy,ultrahigh strength steel,magnetic alloy and surface wear-resistant structural parts. With the urgent weight reduction demand and increasing performance for spacecraft,the lightweight structural materials,represented by aluminum alloys,have become research hotspots. The heat treatment simulation is applied for the thin wall ultrahigh strength steel parts with large length-diameter ratio and variable thickness. The advanced surface hardening technologies,such as plasma nitriding,low pressure carburizing and ion implantation,have also been applied.
