摘要
金属增材制造(AM)是一项革命性的技术进步,已在航空航天、国防、汽车、医疗保健和工程应用等广泛领域取得重大进展。它提供了前所未有的设计自由度,减少了材料浪费,提高了性能,此外还大大改进了制造工艺。制造过程中形成的微结构缺陷和内应力会直接影响制造产品的表面完整性、质量和使用寿命。对这些缺陷进行识别、表征和预测,有助于以高密度直接生产无缺陷结构。本文详细介绍了粉末床熔融和线弧 AM 方法中常见的缺陷、缓解技术和挑战。粉末球形度、粉末粗糙度、预热、工艺参数、构建环境、后处理技术和环境因素都可能导致气孔等缺陷的产生。因此,需要对各种技术、合金、工艺参数优化以及不同的后处理技术进行深入研究,以便从其形成过程中淡化缺陷。
Defects in Metal Additive Manufacturing: Formation, Process Parameters, Postprocessing, Challenges, Economic Aspects, and Future Research Directions.
Metal additive manufacturing (AM) is a revolutionary technological advancement that has made significant inroads in a wide range of sectors, including aerospace, defense, automotive, health care, and engineering applications. It offers unprecedented design freedom, reduced material waste, and enhanced performance, in addition to significant enhancements to fabrication processes. Microstructural defects and internal stresses formed during fabrication directly affect the fabricated product's surface integrity, quality, and service life. Identification, characterization, and prediction of these defects help significant and direct production of defect-free structures with high density. This article provides detailed insights concerning the common defects, mitigation techniques, and challenges reported in both powder bed fusion-based and wire arc AM methods. Defects such as porosity may develop due to the powder sphericity, roughness of the powder, preheating, process parameters, build environment, postprocessing techniques, and environmental factors. Therefore, a critical study of the techniques, alloys, process parameter optimization, and different postprocessing techniques to tone down the defects is made from their formations.
期刊介绍:
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
