Aluminum alloys are used in various industries due to their favorable mechanical properties. In terms of machinability, adding silicon to the chemical composition can provide the association of wear mechanisms. Improvements in wear resistance have been addressed in processes for applying coatings to cutting tools, allowing for work at higher cutting speeds. This study applied microstructural characterization techniques, mechanical and tribological properties that could be correlated with possible performance gains when DLC was applied to carbide tools. Tribological tests indicated resistance to abrasive wear and reduced coefficient of friction when using DLC. During machining tests with aluminum alloy, the presence of DLC provided less significant changes in the quality of holes at different cutting speed.
