在高强度钢的热冲压中，严酷的摩擦条件使得金属板涂层成为工艺技术和经济成功的最关键选择之一。本文介绍了评估热冲压操作中应用于硼钢板的锌基涂层的方法和结果。进行了热模拟和物理模拟实验，以评估涂层和金属板之间的化学相互作用以及在此过程中的摩擦学性能。事实证明，该涂层克服了目前使用的铝硅涂层的大部分缺点。 (C) 2014 Elsevier Ltd. 保留所有权利。
In hot stamping of High Strength Steels, the severe tribological conditions make the metal sheet coating one of the most critical choices for the technical and economical success of the process. This paper presents the approach and the results in evaluating a Zinc-based coating applied to boron steel sheets in hot stamping operations. Thermal and physical-simulation experiments were carried out to evaluate the chemical interactions between the coating and the metal sheet and the tribological performances during the process. The coating proved to overcome most of the drawbacks of the currently utilized Al-Si coating. (C) 2014 Elsevier Ltd. All rights reserved.
