“…Ti atoms incorporating hydrogenated (Ti-H-DLC) coating is suitable for manufacturing processes in turning of Al alloys where sliding-friction is important [19]. Al-Si alloy was machined using coated tools under dry and wet environments in terms of material removal rate, surface roughness, tool wear, and favourable results were produced under wet environments [20].…”

We primarily need to reduce the consumption of metalworking fluid to ensure sustainable and eco-friendly machining of aerospace alloys. The present study was planned to determine the efficiency of various eco-friendly metalworking fluid strategies for the sustainable turning of aerospace aluminium alloy (Al7075-T6) coated carbide tools under different eco-friendly metalworking fluid strategies namely dry machining, minimum quantity lubrication (MQL), Ranque-Hilsch vortex tube (RHVT), and compressed air. Machining performance was investigated in terms of micro-hardness, tool tip temperature, tool wear, cutting forces, work surface roughness, chip morphology, and energy consumed. Results manifested that MQL and tool coatings can significantly lower tool tip temperature by up to 16%, tool wear by up to 102-106%, average cutting forces by 17-21%, and surface roughness reduced from 11-21% as compared to dry conditions.

“…In contrast, carbide tools suffer from severe tool wear, short service life and poor machining quality when used for difficult-to-cut materials such as printed circuit boards and ceramic-based composites [ 5 ]. Many studies have found that depositing a coating on the surface of carbide tools provides the tool with excellent overall performance [ 6 ] and service life [ 7 ], and the use of coated tools can substantially improve machining quality [ 8 ]. Li et al [ 9 ] deposited TiN coatings on carbide tools to improve their cutting performance.…”

An AlCrSiWN coating was prepared on a cemented carbide substrate by the arc ion plating technology. The optimization of the coating process was carried out by matrix analysis of orthogonal experiments to calculate the influence of the process parameters on the hardness, bonding and roughness indexes of the coating, determine the optimal coating process parameters, and focus on the influence of the bias voltage on the microscopic morphology, mechanical properties and friction properties of the coating. The results showed that the influence of the process parameters on the indexes of the orthogonal experiments was in the following order: bias voltage > arc current > N2 flow rate. The optimal solution was achieved with an arc current of 160 A, a bias voltage of −80 V, and a N2 flow rate of 600 sccm. Properly increasing the bias voltage improved the microscopic morphology, mechanical properties and wear resistance of the coating. When the bias voltage was −80 V, the coating surface presented fewer large particles with a less uniform size and no obvious crater defects; in addition, the cross-sectional structure changed from grape-like to columnar, and the coating had higher hardness, lower roughness and better bond strength. In the friction performance test, coating at a −80 V bias voltage showed better wear resistance, which was reflected in lower friction coefficient and wear, and the wear mechanism mainly consisted of adhesion and oxidation wear.
