本文回顾了自1956年以来,近三十年我国航空发动机铸造涡轮叶片的发展历史和现状,归纳了在此期间材料和铸造科研人员提供的铸造高温合金和铸造方法,满足了航空发动机的需要。 在铸造动叶片、空心叶片的陶瓷型芯、弥散强化合金的研究与运用计算机进行质量控制等方面都取得显著的成就。 着眼为将来发展高性能发动机,文中提出研究陶瓷和难熔金属材料以适应下列要求: 1.更高的工作温度 2.更高的表面稳定性 3.更高的力学性能 除了应不怕失败地发展上述材料外,还应考虑高温合金仍是550～1100℃下工作的发动机结构件材料,而且还要使用一段很长的时间。因此,要研究推广计算机的应用。难熔金属模具及真空压铸叶片工艺的改进,将提高叶片质量和代替传统的熔模铸造工艺。
This paper reviews the history and current situation of the development of turbine blades for aero-engine foundry in China since 1956, and summarizes the foundry superalloy and casting methods provided by researchers and researchers during this period to meet the needs of aero-engines. Significant achievements have been made in the research of casting rotor blades, ceramic core of hollow blades, research of dispersion strengthened alloy and quality control by using computer. Focusing on the development of high-performance engines for the future, the paper proposes to study ceramic and refractory metal materials to meet the following requirements: 1. Higher working temperature 2. Higher surface stability 3. Higher mechanical properties In addition to being developed without fear of failure In addition to the above materials, it should also be considered that the high-temperature alloy is still the engine structural material working at 550-1100 ° C, and it still needs to be used for a long time. Therefore, to study the promotion of computer applications. Refractory metal molds and vacuum die-casting blade process improvements, will improve the blade quality and replace the traditional investment casting process.
