Abstract

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.

使用中的 PVD 涂层模具：探索高强度钢板金属成型的有限元分析

本研究建议对高强度钢板的板材金属成型工艺中物理气相沉积涂层模具的使用进行全面分析。该方法旨在研究物理气相沉积涂层如何影响模具性能，以及如何影响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型过程中的机械性能和变形特性。需要研究如何提高这些材料的成型特性，通常以极限拉伸比和最大冲压力表示。观察到所需冲孔力减小，极限拉伸比提高，这归因于模具-板材界面的摩擦接触条件增强。实验结果与 DD3IMP（一种用于拉深模拟的代码）的模拟结果进行了比较，结果表明，实验结果与模拟结果分析吻合。

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
