Abstract

Ti2AlN MAX phase films produced at different N2 flow rates and different annealing temperatures were deposited on 52100 steel substrates using the closed-field unbalanced magnetron sputtering technique. N2 flow rates were changed to 2, 3.5, and 5 sccm. Due to the increasing N2 flow rate, film thickness decreased from 2 to 1.3 µm. Then the produced films were subjected to annealing at temperatures of 700, 750, and 800°C. After the film produced at a flow rate of 2 sccm was annealed at 750°C, the presence of the Ti2AlN MAX phase was determined. The binding energies of Ti 2p, Al 2p, and N 1s determined in the XPS analysis confirmed the existence of the Ti2AlN film. The friction coefficient measured for Ti2AlN MAX phase films was calculated as 0.53, the hardness value as 22.8 GPa, the elastic modulus as 291.4 GPa, and the wear rate as 2.96 × 10−4 mm3/(N·m).

Abstract

Thefatigue properties are very important for cutting tools due to service life. Toimprove fatigue properties of cutting tools, transition metal nitrides withsoft metal (Cu, Ni etc.) have been coated on cutting tool materials. Toinvestigate Cu effect on fatigue properties, TiZrNbN and Cu doped TiZrNbNcoatings were deposited on M2 high speed steel using reactive closed fieldunbalanced magnetron sputtering (CFUBMS) in bias voltage of -80V, coatingpressure of 0.33 Pa and Cu target current of 0.6 A. Microstructure propertiesof the coatings were determined by X-Ray Diffraction (XRD), Scanning ElectronMicroscope (SEM) and Energy Dispersive Spectroscopy (EDS). Mechanicalproperties of the coatings were examined with microhardness tester and scratchtester. Fatigue properties of the coatings were examined using multi-passscratch tester. According to the results, the microhardness of Cu doped TiZrNbNis better than TiZrNbN. On the other hand, the adhesion and fatigue propertiesof TiZrNbN are the highest., Yorulmaözellikleri, kullanım ömrü nedeniyle kesme aletleri için çok önemlidir. Kesicitakımların yorulma özelliklerini iyileştirmek için kesici takım malzemeleriüzerine yumuşak metalle (Cu, Ni vb.) Geçiş metali nitrürleri kaplanmıştır.Yorulma özellikleri üzerindeki Cu etkisini araştırmak için, TiZrNbN ve Cukatkılı TiZrNbN kaplamalar, -80V'luk ön gerilim voltajında, 0.33 Pa'lık kaplamabasıncı ve Cu hedef akımında 0.6 A değerinde reaktif kapalı alan dengesiz manyetikalanda sıçratma (CFUBMS) kullanılarak M2 yüksek hızlı çelik üzerindebiriktirildi. Kaplamaların mikro yapı özellikleri X-Ray Difraktometri (XRD),Taramalı Elektron Mikroskop (SEM) ve Enerji Dağıtıcı Spektroskopi (EDS) ilebelirlenmiştir. Kaplamaların mekanik özellikleri microhardness test cihazı ve çiziktest cihazı ile incelenmiştir. Kaplamaların yorulma özellikleri çok geçişliçizik test cihazı kullanılarak incelenmiştir. Sonuçlara göre, Cu katkılıTiZrNbN'nin mikro sertliği TiZrNbN'den daha iyidir. Öte yandan, TiZrNbN'ninyapışma ve yorulma özellikleri en yüksektir
