摘要

增材技术翻新磨损部件的吸引力需要不同工艺的数据可用性。本研究将等离子体转移电弧(PTA - AM)和直接激光沉积(DLD)两种增材技术应用于IN 625线材上。讨论了每种技术的具体特征，以及它们在恢复磨损部件的几何形状和性能方面的潜在用途。在叶片的某一截面上用每种工艺加工多层材料，并对材料之间的相互作用以及沉积后热处理的效果进行了表征。结果表明，增材制造技术所施加的最终显微组织和与被修复零件的相互作用存在差异。竞争性变化可以通过改变原料来实现。使用粉末材料的PTA-AM表现出接近使用线材的DLD的微观结构。关键词:增材制造;直接激光沉积;PTA, Inconel 625;翻新。

Additive Techniques to Refurbish Ni Based Components

The attractiveness of additive techniques to refurbish worn components requires the availability of data from different process. This study correlates two additive techniques, Plasma Transferred Arc (PTA – AM) and Direct Laser Deposition (DLD), using IN 625 wire. Specific features of each technique are discussed regarding their potential use to recover geometry and properties of worn components. Multilayers were processed with each technique on a section of a blade and the interaction between materials together with the effect of post deposition heat treatment were characterized. Results show that there are differences in the final microstructure and in the interaction with the part being refurbished imposed by the additive technique used. Competitive changes can be made by changing the feedstock. PTA-AM using powder material exhibits a microstructure that approaches that obtained in DLD using wire. Key-words: Additive manufacturing; Direct laser deposition; PTA, Inconel 625; Refurbishing.

期刊介绍： The Journal Soldagem & Inspeção (S&I) js a techno-scientific journal created in 1995. Printed issues of this journal are distributed free of charge to libraries in Brazil, Latin America and the Iberian Peninsula. It has been printed regularly every quarter since September, 2002, and, since the beginning of 2007, its electronic version is available in the address: (http://www.abs-soldagem.org.br/s&i/). The journal is sponsored by the Brazilian Welding Association (ABS). Since its creation several well known professionals working in welding contributed with the Journal Soldagem & Inspeção and its editorial board crosses the Brazilian borders. During its evolution the Journal received ta special contribution from the Editors-in-chief : Ronaldo Paranhos, Américo Scoti, Paulo Modenesi e Alexandre Bracarence. Since January 2012 the Editor-in-chief is Ana Sofia C. M. D’Oliveira, Full professor at Universidade Federal do Paraná (UFPR) . Her work focus mainly on Hardfacing and Physical Metallurgy. The jornal Soldagem & Inspeção also counts with 10 Associate Editors and a fix Editorial board of referees. short-term (Ad Hoc) referees can be invited to evaluate some papers submitted to the journal. The Soldagem & Inspeção journal is the scientific divulgation channel of the Brazilian Welding Association (ABS). It aims to publish original papers related to the scientific and technological development of welding, inspection, and related fields. Review papers or letters on current and controversial subjects are also published in the Journal. Its abbreviated title is Soldag. insp. (Impr.), which should be used in bibliographies, footnotes and bibliographical references and strips.
