摘要: 在硬质合金PCB(printed circuit board)铣刀表面制备高性能的硬质涂层,可以改善切削过程中刀具快速磨损的问题。采用多弧离子镀涂层技术在YG06硬质合金试片及PCB铣刀基体上分别制备AlCrN单涂层、CrN/AlCrN复合涂层以及AlCrSiN/AlCrN纳米复合涂层,利用压痕仪及扫描电镜分析观察3种涂层的力学性能及形貌特征,且在相同条件下对3种PCB涂层铣刀进行涂层性能对比试验,分析刀具磨损机理。结果表明:3种工艺方案的涂层均有较好的膜基结合力;AlCrSiN/AlCrN纳米复合涂层铣刀使用寿命最长,约为CrN/AlCrN复合涂层铣刀的1.5倍,AlCrN单涂层铣刀的1.9倍;且其涂层的致密性和表面质量最好,更适用于IT158覆铜板的高速切削加工。

Abstract: The preparation of a high-performance hard coating on the surface of a carbide PCB (Printed Circuit Board) milling cutter can address the issue of rapid tool wear during cutting. In this study, AlCrN single coating, CrN/AlCrN composite coating and AlCrSiN/AlCrN composite coating were prepared on YG06 cemented carbide specimens and PCB milling cutter substrates by a multi-arc ion plating process, respectively. The mechanical properties and morphological characteristics of the three coatings were observed and analyzed using an indenter and a scanning electron microscope. The above three coated milling cutters were tested under the same conditions, and the coating performance and the tool wear mechanism were compared and analyzed. The results show that the coatings prepared by the above three processes exhibit good film-base adhesion, with the AlCrSiN/AlCrN composite coating milling cutter having the longest service life — approximately 1.5 times that of the CrN/AlCrN coating milling cutter and 1.9 times that of the AlCrN single coating milling cutter. The AlCrSiN/AlCrN composite coating demonstrates the best compactness and surface quality, making it more suitable for high-speed machining of PCB (IT158 copper-clad laminate).-
