绿光粉末床熔融成形铜及铜合金研究进展
Research progress of green laser powder bed fusion of copper and its alloys
摘要
Abstract
The advanced additive manufacturing technology of laser powder bed fusion(LPBF)offers a new approach for the integrated production of copper and its alloy components with complex geometries and high performance.However,the properties of copper materials,such as easy oxidation,high reflectivity,high thermal conductivity,and high melting point,can readily cause defects like melt pool instability,porosity,and stress deformation,which limit the quality of fabrication and application potential.This paper reviews the forming principles and common defect types of LPBF,concentrating on analyzing the main challenges and existing solutions for copper and its alloys in LPBF processing,and highlights recent advances in the use of green lasers for manufacturing pure copper,CuCrZr,and CuCrNb alloys.Focusing on our team's practical experience with green laser LPBF,the study clarifies the advantages of green laser in achieving high-quality fabrication of high-reflectivity materials.Furthermore,the paper explores prospective future directions in laser additive manufacturing of copper and its alloys,including three forefront areas:real-time process monitoring and feedback,beam shaping,and large-scale multi-beam multi-material composite manufacturing.These insights aim to provide a valuable theoretical reference and practical guidance for research innovation and engineering applications in this field.关键词
