Abstract
The Zr-C:H:Nx% coatings with different nitrogen contents have been deposited on AI SI M2 steel substrates and micro-drills by Closed Field Unbalanced Magnetron (CFUBM) sputtering. The tribological properties of the coatings have been tested against AISI 52100 steel balls under loading ION or 100N using an oscillating friction and wear tester. Additionally, high-speed through-hole drilling tests are performed on printed circuit boards (PCB) to investigate tlie drilling performance of the coated micro-drills. The results demonstrate that the excellent tribological properties is Zr-C:H:N8% coating sliding against AISI 52100 steel ball included low wear depth on coating, low friction coefficients and long lifetime. Finally, it is shown that coating micro-drills with Zr-C:H:N8% increases the tool life by a factor of five compared to uncoated micro-drill when used for the high-speed through-hole drilling of PCBs.
