基于PVD电弧镀膜的涂层耐磨性研究

Research on Wear Resistance of Different Coating Based on PVD Arc Deposition

摘要: 本文以球头刀小余量平顺铣削的方式进行了不同PVD(Physical Vapor Deposition)涂层的耐磨性对比研究，避免了刀具铣削过程中因为冲击载荷、散热不充分等因素对涂层耐磨性的影响。研究结果显示，基于(Ti, Al)N系涂层，适当提高Al含量有助于提高涂层的硬度和耐磨性；通过不同步骤的弧电流设计，在表层引入Si元素可将表层硬度提高，涂层耐磨性得到增强。

Abstract: Different PVD (Physical Vapor Deposition) coating materials were investigated by ball-end mill cutting process. The cutting process is under smooth milling with a small margin, which reduced the impact of the cutting load and minimized the heating influence on coating wear performance. The results show that in (Ti, Al)N coating, an alleviated aluminum content increases the vickers hardness and wear resistance. The introduction of silicon into the top layer of (Ti, Al)N improves the hardness further.
