Abstract This work focuses on the effect of Ni on the tribological and milling performance of NbC–Ni films deposited by reactive magnetron sputtering. High temperature tribological performance of films was studied through reciprocating dry sliding experiments. The milling performance of the coatings was evaluated in a CNC machining center. Results showed that the coefficient of friction of the Nb0.43Ni0.13C0.44 film was the lowest at room temperature, whereas, at high temperature, it was not significantly changed for the films with lower Ni content. It decreased for the Nb0.36Ni0.24C0.40 film. The flank wear resistance was enhanced when compared to the uncoated tool. Crater wear and severe chipping were the main wear mechanisms observed for the uncoated tool, while the coated tools evidenced mainly adhesive and abrasive wear and nose chipping.

不同Ni含量溅射沉积的NbC-Ni薄膜的摩擦学和铣削性能

摘要 这项工作的重点是镍对反应磁控溅射沉积的 NbC-Ni 薄膜的摩擦学和铣削性能的影响。通过往复干滑动实验研究了薄膜的高温摩擦学性能。涂层的铣削性能在数控加工中心进行评估。结果表明，Nb0.43Ni0.13C0.44薄膜的摩擦系数在室温下最低，而在高温下，Ni含量较低的薄膜摩擦系数变化不大。对于 Nb0.36Ni0.24C0.40 薄膜，它降低了。与未涂层刀具相比，后刀面耐磨性得到增强。月牙洼磨损和严重崩刃是未涂层刀具观察到的主要磨损机制，而涂层刀具主要表现为粘着磨损和磨粒磨损以及刀尖崩刃。
