Abstract

The aim of this work is to evaluate the microstructural evolutions developed by mixing a corrosion-resistant and high-performance material with a high-hardness material in a coating obtained by laser-cladding technology. In this paper, five different mixtures of Inconel 625 alloy and AISI H13 steel powders have been deposited on a plate of 42CrMo4 steel using a 2.2 kW diode pumped Nd:YAG laser. The effect of adding tool steel to a Ni-based superalloy has been analyzed by the characterization of each cladded sample using optical microscopy and scanning electron microscopy (SEM). The precipitates observed in the samples have been analyzed by energy dispersive X-ray spectroscopy (EDS X-ray). SEM micrographs and EDS analysis indicate the existence of Laves phase. It has been observed that the presence of these precipitates is stabilized in a certain range of AISI H13 addition.

摘要

这项工作的目的是评估通过激光熔覆技术获得的涂层中，将耐腐蚀高性能材料与高硬度材料混合后所产生的微观结构演变。本文使用一台2.2千瓦二极管泵浦Nd:YAG激光器，将五种不同比例的因科镍合金625和AISI H13钢粉末混合物熔覆在一块42CrMo4钢板上。通过使用光学显微镜和扫描电子显微镜（SEM）对每个熔覆样品进行表征，分析了向镍基高温合金中添加工具钢的效果。利用能量色散X射线光谱仪（EDS X射线）对样品中观察到的析出物进行了分析。扫描电子显微镜图像和EDS分析表明存在拉夫斯相。据观察，在一定范围内添加AISI H13时，这些析出物的存在得以稳定。
