Abstract

In this study, we investigated the heat treatment effects on tribological behaviour between Al–Si coated 22MnB5 and SKD61 tool steels in hot stamping process using a high temperature tribosystem developed based on a strip drawing method. Heat treatments were conducted at 900 and 930 °C for durations of 220–600 s prior to friction testing. The results indicated that variations in heat treatment significantly impact porosity, oxide formation, and intermetallic compounds, thereby altering wear behaviour. Differences in heat treatment conditions led to variations of the total heat applied to the steel sheets, which influenced the diffusion of Al into the substrate and Fe into the coating. These diffusional differences underlay the distinct porosity, oxide formation, and intermetallic composition observed with each treatment, which in turn impacted wear behaviour. Under conditions of 900 °C for 220 s, unalloyed aluminium remained on the surface, intensifying adhesive wear due to increased adhesion to the tool. In contrast, at 930 °C for 220 s, aluminium alloying was promoted, forming a substantial Fe2Al5 phase that increased adhesive wear. Under conditions of 900 °C for 600 s and 930 °C for 600 s, the increased temperature and duration influenced porosity levels, with the higher porosity observed at 930 °C for 600 s, leading to increased debris formation and enhancing adhesive wear. These findings provide the potential to optimise wear behaviour and tool life in hot stamping applications by adjusting heat treatment parameters.

Graphical Abstract

热处理对Al-Si涂层22MnB5和SKD61工具钢热冲压摩擦学性能的影响
在这项研究中,我们研究了热处理对Al-Si涂层22MnB5和SKD61工具钢在热冲压过程中的摩擦学行为的影响,采用基于带拉伸法开发的高温摩擦系统。在摩擦测试之前,在900°C和930°C下进行220-600 s的热处理。结果表明,热处理的变化会显著影响孔隙度、氧化物形成和金属间化合物,从而改变磨损行为。热处理条件的不同导致施加到钢板上的总热量的变化,这影响了Al向基体和Fe向涂层的扩散。这些扩散差异是在每种处理中观察到的不同孔隙度、氧化物形成和金属间成分的基础上形成的,这反过来又影响了磨损行为。在900°C、220 s的条件下,非合金铝仍留在表面,由于与工具的附着力增加,加剧了粘着磨损。相比之下,在930℃下保温220 s,铝的合金化得到促进,形成大量的Fe2Al5相,增加了粘接磨损。在900℃600 s和930℃600 s的条件下,温度和持续时间的增加影响了孔隙率水平,在930℃600 s下观察到更高的孔隙率,导致碎屑形成增加,增强了粘着磨损。这些发现为通过调整热处理参数来优化热冲压应用中的磨损行为和工具寿命提供了潜力。图形抽象

期刊介绍: Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
