Abstract In this study, a-C:Ti$_{ x%}$ coatings with various levels of Ti addition are deposited on cemented tungsten carbide (WC-Co) substrates using a medium-frequency twin magnetron sputtering and unbalanced magnetron sputtering system. This study investigates the tribological properties of the coatings by conducting wear tests against an AISI 1045 steel counterbody under a cylinder-on-disk line contact wear mode using an oscillating friction and wear tester. Additionally, turning tests and high-speed through-hole drilling tests are performed on AISI 1045 steel counterbodies and PCB workpieces, respectively, to investigate the machining performance of coated turning cutters and microdrills. The a-C:Ti$_{ x%}$ coatings not only have improved tribological properties but also demonstrate enhanced machining performance. For sliding against the AISI 1045 steel counterbody under loads of 10 and 100 N, the results show that the optimal friction and wear resistance properties are provided by the a-C:Ti$_{13%}$ and a-C:Ti$_{3%}$ coatings, respectively. Meanwhile, the a-C:Ti$_{20%}$ and a-C:Ti$_{51%}$ coatings yield the optimal turning and drilling performance, respectively.
