Abstract

The purpose of this research was to enhance the wear behavior and hardness of cold work D5 tool steel by depositing a TiCrN multilayer nanocoating through the physical vapor deposition with a cathodic arc. A comparison was made between the properties of the applied coatings and the thin-film TiN and CrN nanolayer coatings produced using the same method. Various tests, including micro-hardness tests, surface wear tests, and corrosion examinations using the Tafel test, were conducted. The coating surfaces and the wear lines were analyzed using field emission scanning electron microscopy with energy dispersive X-ray spectroscopy. The results indicated that the TiN thin-film coating, the TiCrN multilayer nanocoating and the CrN coating exhibited higher hardness of 226, 205, and 165 HV, respectively than the less coated sample (101 HV). Additionally, friction coefficients were measured and found to be 0.35, 0.3, and 0.27 for TiN, TiCrN, and CrN coatings, respectively. Furthermore, the corrosion test results demonstrated that the TiCrN multilayer coating exhibited excellent corrosion resistance. The analysis of wear surfaces revealed abrasion wear mechanisms for the TiN and CrN coatings, while fatigue wear mechanisms were observed for the TiCrN coating. Those findings suggest that the TiCrN multilayer nanocoating has potential applications in the production of tool steel pieces, complementary parts, and machine tool components.

通过物理气相沉积 TiCrN 多层纳米涂层改善 D5 冷作工具钢的磨损性能和硬度

摘要本研究的目的是通过阴极电弧物理气相沉积法沉积 TiCrN 多层纳米涂层，从而提高冷作 D5 工具钢的磨损性能和硬度。比较了所应用涂层的性能和使用相同方法生产的薄膜 TiN 和 CrN 纳米层涂层的性能。进行了各种测试，包括显微硬度测试、表面磨损测试和使用 Tafel 试验进行的腐蚀检测。使用场发射扫描电子显微镜和能量色散 X 射线光谱分析了涂层表面和磨损线。结果表明，TiN 薄膜涂层、TiCrN 多层纳米涂层和 CrN 涂层的硬度分别为 226、205 和 165 HV，高于涂层较少的样品（101 HV）。此外，经测量发现，TiN、TiCrN 和 CrN 涂层的摩擦系数分别为 0.35、0.3 和 0.27。此外，腐蚀测试结果表明，TiCrN 多层涂层具有优异的耐腐蚀性。对磨损表面的分析表明，TiN 和 CrN 涂层具有磨损机制，而 TiCrN 涂层则具有疲劳磨损机制。这些研究结果表明，TiCrN 多层纳米涂层在工具钢部件、互补部件和机床部件的生产中具有潜在的应用价值。
