Abstract

In the production of pipes from corrosion-resistant steels on tube rolling mills, a relevant problem is the low durability of the pipe tooling. Therefore, the creation of high-performance and durable tools is primarily associated with obtaining and processing materials capable of withstanding harsh working conditions. The paper analyzes the structure and properties of the nitrogenated layer formed on the surface of the stamping tool made of X40CrMoV5-1-1 steel using the ion-plasma nitriding technology in a two-stage vacuum-arc discharge, aimed at improving the wear resistance of the pipe pressing tool. The article proposes, substantiates, and calculates a mathematical model of microhardness distribution with depth of the diffusion layer based on the Kolmogorov-Johnson-Mehl-Avrami equation, which takes into account phase transformations associated with reaction diffusion processes during nitriding. An analysis of the thermodynamic stability of nitride diffusion zones responsible for improving the wear resistance of the tool is provided.

离子-等离子体两级真空-气相沉降法获得的 X40CrMoV5-1-1 钢氮化层的结构和性能

在轧管机上用耐腐蚀钢材生产钢管时，一个相关的问题是钢管模具的耐用性较低。因此，制造高性能和耐用的工具主要与获取和加工能够承受恶劣工作条件的材料有关。本文分析了在两级真空电弧放电中使用离子等离子氮化技术在 X40CrMoV5-1-1 钢冲压工具表面形成的氮化层的结构和特性，旨在提高管材冲压工具的耐磨性。文章基于 Kolmogorov-Johnson-Mehl-Avrami 方程提出、证实并计算了显微硬度随扩散层深度分布的数学模型，该模型考虑了氮化过程中与反应扩散过程相关的相变。该方程考虑了氮化过程中与反应扩散过程相关的相变，并对氮化扩散区的热力学稳定性进行了分析，氮化扩散区的作用是提高刀具的耐磨性。
