“…The columnar morphology of the TiAlN became denser with an increasing nitrogen flow rate, which may increase the coating hardness [15]; however, the present study results show that, generally, the coating hardness decreased with the increase of the nitrogen flow rate. This is probably due to the new phase formation from the reaction between Al and N [11,16]. A small and disordered new phase could not be detected in the XRD measurement due to the weak diffraction intensity.…”

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.

“…As regards coated samples, since produced nitride coatings have a sufficient adhesion strength, the wear mechanism should be chiefly ruled by the surface interaction of tribologically coupled materials [ 54 , 55 ]. In addition, the slightly improved toughness observed in the scratch tests after testing could favor wear resistance.…”

Thermal Shock and Oxidation Behavior of HiPIMS TiAlN Coatings Grown on Ti-48Al-2Cr-2Nb Intermetallic Alloy

A High Power Impulse Magnetron Sputtering (HiPIMS) method for depositing TiAlN environmental barrier coatings on the surface of Ti-48Al-2Cr-2Nb alloy was developed in view of their exploitation in turbine engines. Three differently engineered TiAlN films were processed and their performance compared. Bare intermetallic alloy coupons and coated specimens were submitted to thermal cycling under oxidizing atmosphere up to 850 °C or 950 °C, at high heating and cooling rates. For this purpose, a burner rig able to simulate the operating conditions of the different stages of turbine engines was used. Microstructures of the samples were compared before and after each test using several techniques (microscopy, XRD, and XPS). Coating-intermetallic substrate adhesion and tribological properties were investigated too. All the TiAlN films provided a remarkable increase in oxidation resistance. Good adhesion properties were observed even after repeated thermal shocks. HiPIMS pretreatments of the substrate surfaces performed before the coating deposition significantly affected the oxidation rate, the oxide layer composition and the coating/substrate adhesion.

“…The working principle and advantages of the tester have been described by the current authors recently [15]. Cohesive failures leading to appearance of failures within the films could be easily identified after a certain number of impact cycles, while adhesive failures, taking as the load at which the first exposure of the substrate, was selected as the failure criterion.…”
