在本研究中,采用实验分析和有限元建模(FEM)研究了由 Cr3C2-NiCr 中间层和顶部 AlCrN 薄膜组成的双层涂层的微观结构和机械性能,并与单层 AlCrN 薄膜进行了比较。结果表明,与单层AlCrN薄膜相比,AlCrN/Cr3C2-NiCr双相涂层的附着强度、承载能力、H/E和H3/E2比以及硬度都有显着提高,特别是在重载荷下的耐磨性提高了近8倍。此外,有限元分析表明,双相设计减少了AlCrN薄膜表面的应力集中区域,使其在承载过程中远离接触界面。
In this study, experimental analysis and finite element modeling (FEM) were employed to investigate the microstructure and mechanical properties of duplex coatings composed of a Cr3C2–NiCr interlayer and a top AlCrN film in comparison with these of a single AlCrN film. Results showed a significant improvement in the adhesive strength, load-bearing capacity, H/E, and H3/E2ratios, and hardness of the AlCrN/Cr3C2–NiCr duplex coatings compared to the single AlCrN film, especially the wear resistance that increased by nearly eight times under heavy loads. Moreover, FEM analysis revealed that the duplex design reduced the stress concentration area on the surface of AlCrN film and kept it far away from the contact interface during load-bearing.
