“…The TiAlN coating hardness increased with an increasing nitrogen flow rate due to the presence of the AlN phase along with the TiN phase [5]; however, a further increase in the nitrogen flow rate increases the presence of the AlN phase, and it is not useful for the wear resistance application. The TiAlN coating hardness increased with an increasing nitrogen flow rate due to the increase of the nitrogen content [12].…”

“…The hardness of the TiAlN coating also increased with the increasing nitrogen flow rate, but it had low wear resistance [5]. An early finding was reported that better wear resistance was shown by the TiAlN-coated insert deposited at a high nitrogen flow rate above the critical nitrogen flow rate [6].…”

The effect of the sputtering parameters on the mechanical tribology properties of Titanium Aluminum Nitride coating on the tungsten cabide insert tool in the dry turning of tool steel has been investigated. The coating was deposited using a Direct Current magnetron sputtering system with various substrate biases (-79 to -221 V) and nitrogen flow rates (30 to 72 sccm). The dry turning test was carried out on a Computer Numeric Code machine using an optimum cutting parameter setting. The results show that the lowest flank wear (~0.4 mm) was achieved using a Titanium Aluminum Nitride-coated tool that was deposited at a high substrate bias (-200 V) and a high nitrogen flow rate (70 sccm). The lowest flank wear was attributed to high coating hardness. AbstrakSifat Mekanik dan Tribologi Lapisan Titanium Aluminium Nitrida pada Perkakas Tungsten Karbida dalam Pemotongan Kering Baja. Telah dilakukan penelitian mengenai pengaruh parameter sputering terhadap sifat mekanik dan tribologi lapisan Titanium Aluminum Nitrida pada perkakas potong tungsten karbida dalam proses pemotongan turning kering baja perkakas. Deposisi lapisan tipis dilakukan menggunakan sistem sputtering magnetron dengan variasi tegangan substrate (-79 s/d -221 Volt) dan laju alir gas nitrogen (30 s/d 72 sccm). Pemotongan turning kering dilakukan menggunakan mesin bubut otomatis CNC dengan parameter pemotongan optimum. Hasil percobaan menunjukan bahwa aus sisi terendah (~0.4 mm) perkakas ditunjukan oleh lapisan Titanium Aluminum Nitrida yang dideposisikan pada tegangan substrat (-200 V) dan laju alir gas nitrogen (70 sccm) tinggi. Rendahnya aus sisi perkakas diakibatkan oleh tingginya nilai kekerasan lapisan.

“…The present study results show that the flank wear of the TiAlN-coated insert decreases with an increasing nitrogen flow rate. The decrease of the flank wear with the increasing nitrogen flow rate may be due to the presence of the AlN phase along with the TiN phase; however, increasing the AlN presence further is not useful for wear resistance application [5].…”

“…2). The behavior of COF for the TiAlN-100Cr6 pair was also influenced by the metallic nature of 100Cr6 counterpart, which tends to produce fragile oxidation products with high and unstable friction [32]. Previous chemical studies of the wear track have shown the formation of mixed Fe and Al oxides, that promotes oxidative and abrasive wear mechanisms (ploughing) [32], [33].…”

This work aims to study the effect of the counterpart materials (100Cr6, Al2O3 and WC-Co) on the tribological properties of TiAlN thin films deposited on AISI H13 steel substrate by reactive magnetron co-sputtering. The structural characterization of the TiAlN films, performed by X-ray diffraction, showed (220) textured fcc crystalline structure. The values of hardness and elastic modulus obtained by nanoindentation were 27 GPa and 420 GPa, respectively, which resulted in films with a relatively high resistance to plastic deformation. Ball-on-disk sliding tests were performed using normal loads of 1 N and 3 N, and 0.10 m/s of tangential velocity. The wear coefficient of the films was determined by measuring the worn area using profilometry every 1000 cycles. The mechanical properties and the chemical stability of the counterpart material, debris formation and the contact stress influences the friction and the wear behavior of the studied tribosystems. Increasing the hardness of the counterpart decreases the coefficient of friction (COF) due to lower counterpart material transference and tribofilm formation, which is able to support the contact pressure. High shear stress concentration at the coating/substrate interface was reported for higher load promoting failure of the film-substrate system for all tribopairs.
