Technology development and roadmap of electron beam additive manufacturing for aviation equipments

Abstract

Additive manufacturing technology has a broad development prospect in the field of aviation equipments. As an important metal additive manufacturing process, the electron beam additive manufacturing is in a rapid development stage. The wire-feed electron beam additive manufacturing can meet the requirements of rapid and low-cost manufacturing of aviation large size structural parts and can be used to repair high-value damaged parts. Electron beam selective melting has obvious advantages in the manufacturing of complex structures and refractory alloy parts. Based on the analysis of the state-of-arts of the electron beam additive manufacturing technology, the roadmap of the electron beam additive manufacturing for aviation equipments in 2035 is comprehensively analyzed and drawn from the five aspects of development needs, objectives, common key technologies, applications, strategic support and guarantee in order to provide reference for the development of the electron beam additive manufacturing technology of aviation equipments. In 2035, a perfect additive manufacturing standard system is to be built; and electron beam additive manufactured key load bearing components for airplane andaeroengine realize mass production and application.
