目前的工作涉及两种不同类型涂层的耐刮擦性表征，即分别通过物理气相沉积和等离子体增强化学气相沉积在 X42Cr13/W (1.2083) 塑料模具工具钢上制备的氮化铬 (CrN) 和类金刚石碳。我们的研究重点是双相处理，即等离子氮化 + 陶瓷涂层对工具钢耐划伤性的影响。先进的 3D 划痕测试方法已用于研究划痕过程中的涂层附着力和损坏机制。通过球坑试验和显微维氏试验完成划痕分析，以确定涂层的厚度和硬度。测试结果表明，所应用的双相处理是一种明显有利的表面技术工艺，其表现在双相涂层具有更高的承载能力和更低的开裂敏感性，从而增加了临界力。复合基材/涂层材料系统的耐刮擦性通过较硬的基材材料得到增强，为两种类型的陶瓷涂层提供更好的界面结合，而不改变基本的损坏机制。
The present work deals with the characterization of the scratch resistance of two different types of coatings, i.e., chromium nitride (CrN) and diamond-like carbon prepared on X42Cr13/W (1.2083) plastic mold tool steel by physical vapor deposition and plasma-enhanced chemical vapor deposition, respectively. Our study focuses on the influence of the duplex treatment, i.e., plasma nitriding + ceramic coating on the scratch resistance of the tool steel. An advanced 3D scratch testing methodology has been used to investigate the coating adhesion and damage mechanism during scratching. The scratch analysis is completed by ball cratering test and micro-Vickers test to determine the thickness and hardness of the coatings. The test results demonstrate that the applied duplex treatment is an unambiguously advantageous surface technological process which manifests itself in higher loadability and lower sensitivity for cracking of the duplex coatings, increasing the critical forces. The scratch resistance of the combined substrate/coating material system is enhanced by the harder substrate material, providing a better interfacial bonding for both types of the ceramic coatings without changing the basic damage mechanisms.
