等离子渗氮处理被批准用于减少热锻造应用领域中发生的磨损。但需要进一步优化工艺，以便为不同负载的锻造工具实现合适的性能。这项工作介绍了主要工艺参数对模具磨损行为的影响。这项工作的重点钢材是 DIN-X38CrMoV5-1 (1.2343)，一种标准热成型工具钢。研究了氮化温度、氮气流量和时间等氮化参数对氮化深度、硬度和裂纹敏感性的影响。对比应用测试显示了不同表面处理对工业环境中锻造工具的磨损行为和寿命的影响。 (c) 2012 年弗罗茨瓦夫斯卡理工大学。由 Elsevier Urban & Partner Sp. 出版。 z o.o.版权所有。
Plasma nitriding treatments are approved to reduce wear occurring in the field of hot forging applications. But there are demands for a further optimization of the processes in order to achieve adapted properties for differently loaded forging tools. This work presents the influence of main process parameters on the wear behavior of dies. The focused steel material of this work is DIN-X38CrMoV5-1 (1.2343), a standard hot forming tool steel. The influence of nitriding parameters like temperature, nitrogen flow and time on the nitriding depth, hardness and crack sensitivity has been investigated. Comparative application tests show the influence of different surface treatments on the wear behavior and lifetime of forging tools in an industrial environment. (c) 2012 Politechnika Wroclawska.
