Despite the surge in plasma nitriding research, few reviews thoroughly examine how surface decarburization-occurring both before and during the treatment-affects AISI 4140 and similar steel grades. This review addresses that shortfall by providing an investigation into the decarburization process and its consequences. It compiles essential findings from prior studies, demonstrating instances of decarburization in both plasma-free and plasma-containing environments. Furthermore, this analysis explores strategies to prevent decarburization and assesses its significant impact on the steel's microstructure, hardness, corrosion resistance, and wear properties in surface and near-surface regions. Moreover, this study proposes directions for future research, emphasizing the necessity for a more detailed understanding of the decarburization mechanisms and their influence on the properties of plasma-nitrided steels.
尽管等离子体渗氮研究激增，但很少有综述全面研究在处理之前和处理过程中发生的表面脱碳如何影响AISI 4140及类似钢种。本综述通过对脱碳过程及其后果进行调查来弥补这一不足。它汇编了先前研究的重要发现，展示了在无等离子体和含等离子体环境中的脱碳实例。此外，该分析探讨了防止脱碳的策略，并评估了其对钢的微观结构、硬度、耐腐蚀性以及表面和近表面区域磨损性能的重大影响。此外，本研究提出了未来研究的方向，强调需要更详细地了解脱碳机制及其对等离子体渗氮钢性能的影响。
