Abstract

Due to their exceptional properties, low-cost high-carbon steels have long been extensively utilized in many industrial applications. However, their corrosion resistance is poor for many applications and requires further enhancement. Various methods have been developed to achieve this, but they suffer from some limitations. In the work presented herein, a single-stage heat treatment process was applied at low temperature and utilizing waste materials for comparison as new resources, being shown to be a cost-effective approach. In the framework of this study, a multi-hybrid coating structure was developed on the surface of high-carbon steel by applying a single-step heat treatment process and utilizing various waste materials, namely metallurgical slag, glass, and automotive shredder residue (ASR). The results reveal that not only was the process completed in a short time but significant enhancements in the corrosion resistance and hardness performance were achieved. Analyses were performed by high-resolution laser scanning confocal microscopy, electron probe microanalysis (EPMA), focused ion beam-scanning electron microscopy (FIB-SEM), and atomic force microscopy (AFM) in peak force quantitative nanomechanical (PF-QNM) mode. The electrochemical corrosion performance was tested using Tafel method. Both the Young’s modulus and corrosion resistance of the steels treated using the waste materials were improved compared with the base material. This approach opens a new perspective for utilizing waste materials to obtain environmentally sustainable products in a cost-effective fashion, thereby reducing reliance on new resources as well as disposal of waste materials in landfill.

废物整合多杂化结构增强高碳钢耐蚀性的表征

摘要

由于其优异的性能,低成本高碳钢长期以来已在许多工业应用中得到广泛利用。但是,它们的耐腐蚀性在许多应用中很差,需要进一步增强。已经开发出各种方法来实现这一点,但是它们受到一些限制。在本文介绍的工作中,在低温下应用了一步热处理工艺,并利用废料进行比较作为新资源,这被证明是一种经济高效的方法。在这项研究的框架内,通过采用单步热处理工艺并利用各种废料,即冶金渣,玻璃和汽车残渣(ASR),在高碳钢表面开发了一种多混合涂层结构。 )。结果表明,不仅该过程在短时间内完成,而且耐蚀性和硬度性能得到了显着提高。通过峰力定量纳米力学(PF-QNM)模式的高分辨率激光扫描共聚焦显微镜,电子探针显微分析(EPMA),聚焦离子束扫描电子显微镜(FIB-SEM)和原子力显微镜(AFM)进行分析。 。使用Tafel方法测试电化学腐蚀性能。与基础材料相比,使用废料处理的钢的杨氏模量和耐蚀性均得到改善。这种方法为利用废料以具有成本效益的方式获得环保产品提供了新的视角,
