This research proposes a complete analysis of the use of physical vapour deposition coated dies in the sheet metal forming process for high‐strength‐steel sheets. The goal of the proposed approach is to investigate how PVD coatings affect die performance and how that affects the formability and quality of the high‐strength‐steel‐sheets that are made. The finite element analyses are used to simulate and evaluate the mechanical behaviour and deformation characteristics during the forming process. Studies to enhance the forming characteristics of these materials, typically denoted by limiting draw ratio and maximum punch force are required. A reduction in punch force required and improved limiting draw ratio is observed that is attributed to the enhanced contact with friction‐conditions in the die‐sheet interfaces. The experimental results are compared with simulation results from DD3IMP, a code used for deep drawing simulations, and it is evident that the experimental outcomes are analysed well with the simulation results.

PVD 涂层模具的实际应用：探索高强度钢板材成形的有限元分析

这项研究提出了对物理气相沉积涂层模具在高强度钢板板材成形过程中的使用的完整分析。所提出方法的目标是研究 PVD ​​涂层如何影响模具性能以及如何影响所制造的高强度钢板的成型性和质量。有限元分析用于模拟和评估成形过程中的力学行为和变形特征。需要进行研究以增强这些材料的成形特性，通常通过限制拉伸比和最大冲裁力来表示。观察到所需冲头力的减少和极限拉伸比的提高，这是由于模片界面中摩擦条件的接触增强。将实验结果与DD3IMP（用于拉深仿真的代码）的仿真结果进行比较，很明显，实验结果与仿真结果进行了很好的分析。
