Abstract
The increasing speed of high-speed trains has aggravated wheel wear, posing a major threat to the safety of vehicle operation. In this study, CL60 steel was coated with Fe-based alloy powder by the laser cladding method. The microstructure and wear resistance of the coating were investigated. In addition, the dynamic properties of the wheelset model before and after cladding were also analyzed. The results showed that the best cladding effect was achieved at laser power of 700 W. The wear resistance and micro-hardness of the specimen were significantly improved by cladding. The dynamic performance of both coated and uncoated wheelset models meets the requirements of GB5599-2019. However, the coated wheelset model showed better dynamic performance than the uncoated wheelset model.
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
