Abstract

Laser directed energy deposition (LDED) can be deployed for depositing high-performance materials for various engineering applications. Alumina-forming steel is a high-performance material that possesses excellent corrosion and oxidation resistance, finding application in the power generation sector. In the present work, LDED using powder feeding (LDED-PF) was used to deposit Fe20Cr5.5AlY alloy using single-track, multi-track, and multi-layer deposition on SS 316L substrate. Response surface methodology (RSM)-based optimization was used to optimize the single-track deposition. The relationship between the track geometry parameters and the build rate with the LDED-PF processing parameters was studied. Further, the nonlinear relationship among the major process parameters was developed and an analysis of variance (ANOVA) was utilized to find significant parameters. The multi-track deposition yielded densely clad layers with a columnar grain structure. The presence of complex oxide slag of Y, Al, and Zr on the clad layer was detected. A micro-hardness of 240–285 HV was observed in the clad layer, with a hardness of 1088–1276 HV at the slag layer. The multi-layered structures showed a relative density of 99.7% with columnar growth and an average microhardness of 242 HV. The study paves the way for the deposition of dense alumina-forming steel structures for building components for power generation applications.

基于激光定向能量沉积的Fe20Cr5.5AlY从单道到块体结构的增材制造：统计分析、工艺优化和表征

激光定向能量沉积（LDED）可用于沉积各种工程应用的高性能材料。氧化铝成型钢是一种具有优异耐腐蚀性和抗氧化性的高性能材料，在发电领域有着广泛的应用。在本工作中，使用粉末进给LDED（LDED-PF）在SS 316L衬底上采用单道、多道和多层沉积的方法沉积Fe20Cr5.5AlY合金。采用基于响应面法（RSM）的优化方法对单轨沉积进行了优化。研究了LDED-PF处理参数与轨道几何参数和构建速率之间的关系。此外，开发了主要工艺参数之间的非线性关系，并利用方差分析（ANOVA）来寻找重要参数。多轨道沉积产生了具有柱状晶粒结构的致密包覆层。检测到覆层上存在Y、Al和Zr的复合氧化物渣。在覆层中观察到240–285 HV的显微硬度，在渣层处观察到1088–1276 HV的硬度。多层结构的相对密度为99.7%，柱状生长，平均显微硬度为242HV。该研究为沉积用于发电应用的建筑构件的致密氧化铝成型钢结构铺平了道路。
