本文针对Ni3Al基合金IC10进行过渡液相扩散焊技术研究,研制专用中间层,分析接头组织变化规律及其与接头强度的关系,实现TLP扩散焊技术在IC10合金导向叶片的工程应用。航空科学技术的发展,促使航空发动机性能不断提高,具体体现在航空发动机朝高温、轻量化方向发展。目前用于制造航空发动机热端部件的高温合金无法满足高推比发动机耐温性能的要求,
In this paper, Ni3Al-based alloy IC10 transition liquid phase diffusion welding technology research, development of special intermediate layer, analysis of joint changes in the rules and the strength of the relationship between the joints, TLP diffusion welding technology in IC10 alloy guide vane engineering applications. The development of aviation science and technology has led to the continuous improvement of aeroengine performance, which is embodied in the development of aeroengine towards high temperature and light weight. At present, the high-temperature alloys used to manufacture the hot-end components of aero-engine can not meet the requirements of high-temperature resistance performance of engine,
