Abstract

The paper shows the results related to regeneration possibilities analysis of a damaged slider removed from a hydraulic splitter that was repaired using additive manufacturing (AM), laser-based powder bed fusion of metals (PBF-LB/M) technology. The results demonstrate the high quality of the connection zone between the original part and the regenerated zone. The hardness measurement conducted at the interface between the two materials indicated a significant increase equal to 35% by using the M300 maraging steel, as a material for regeneration. Additionally, the use of digital image correlation (DIC) technology enabled the identification of the area where the largest deformation occurred during the tensile test, which was out of the connection zone between the two materials.

摘要

本文展示了与从液压分流器上拆下的损坏滑块再生可能性分析相关的结果，该滑块采用增材制造（AM）、基于激光的金属粉末床熔融（PBF-LB/M）技术进行修复。结果表明原始部件与再生区域之间连接区域的高质量。在两种材料之间的界面处进行的硬度测量表明，使用M300马氏体时效钢作为再生材料时，硬度显著增加了35%。此外，数字图像相关（DIC）技术的使用能够识别拉伸试验期间发生最大变形的区域，该区域不在两种材料的连接区域内。
