Research and application progress of airworthiness grade titanium alloy powder for additive manufacturing in the field of civil aviation
Additive manufacturing technology has great application advantages in rapid trial and iteration of part configuration,integrated forming of complex parts,and structural weight reduction. With the development of civ-il aviation,more demands have been put forward for laser additive manufacturing. Metal powder,as the founda-tion of additive manufacturing,plays a crucial role in the quality of laser additive manufacturing. This article takes titanium alloy powder for civil aviation as the object,sorts out the preparation process and performance evaluation of additive manufacturing metal powder,compares the requirements of airworthiness quality,elabo-rates on the research and application progress of additive manufacturing titanium alloy powder in civil aviation,and analyzes the bottlenecks and challenges that restrict the further batch production and application of additive manufacturing metal powder in civil aircraft.
