“…It was shown that when the amount of Al is high (50-77 %) and the temperature is high, the energy required for the Al atoms to be embedded in the lattice is higher than that for the H-AlN nucleation, and the H-AlN phase is easily formed. [11][12][13] In this study, the EDS analysis of various coatings indicates that the Al amount is above 50 %, which is in agreement with the results of the reference studies ( Figure 3). The grain size was calculated with the Scherrer formula.…”

A series of CrAlN and TiAlN hard coatings were prepared using industrial arc-ion plating with or without the embedded axial electromagnetic filtration technology. The microstructure evolution and mechanical properties of the hard coatings were compared after annealing. The results show that the grain size of the hard coatings prepared with an arc induced by an electromagnetic field decreases significantly, and the quantity of pits and hard particles reduces, leading to an improvement of compactness. Furthermore, the wear resistance and the thermal stability of the coatings prepared with electromagnetic fields improve significantly.

“…AlCrN has better wear resistance due to the formation of permanent oxide layers on the worn surfaces. AlCrN coatings can be produced by various methods, including magnetron sputtering (Ref [14][15][16][17][18], HIPIMS (Ref [19][20][21] and cathodic arc evaporation ( Ref 8,9,[22][23][24][25]. Dependent on the deposition method applied and the technological parameters of coating deposition, different structure and mechanical properties can be obtained.…”

AlCrN coatings were deposited on steel substrates (HS6-5-2) using cathodic arc evaporation. The effect of nitrogen pressure on the properties of CrAlN coatings formed from Al 80 Cr 20 cathode, such as chemical and phase composition of the coatings, surface morphology, deposition rate, hardness and adhesion to the substrate, and friction and wear were investigated. The coating deposited at nitrogen pressure of 3 Pa shows the highest deposition rate. The roughness parameter Ra of the coating surface decreases with increasing nitrogen pressure during its formation. The test results showed that the AlCrN coatings deposited under nitrogen pressure in the range from 1 to 5 Pa show similar hardness for all the coatings, which is around 17 GPa. The increase in the negative bias voltage of the substrate during the formation of the coating deteriorates its adhesion to the substrate, although the wear rate is rather good, about 1.4 3 10 27 mm 3 /Nm. The coatings deposited at nitrogen pressure of 3-4 Pa are characterized by the highest critical load, 95 N. Despite worse adhesion, these coatings are characterized by high resistance to wear, the wear rate is about 1.4 3 10 27 mm 3 /Nm.

“…1). The as-deposited AlCrN coating was mainly composed of (Cr,Al)N solid solution phases with a face-centred cubic structure (fcc), without any compounds containing Al [27], and an austenitic (substrate phase) was also detected. In addition to this (Cr,Al)N phase, some AlN phases with a hexagonal close packed structure (hcp) were observed in the AlCrN coating annealed at 700 °C.…”

AlCrN coatings were deposited on 316L stainless steel by multi-arc ion plating. The phase structures were controlled and optimised by vacuum annealing at 700 °C, 800 °C, and 900 °C, each for 2 hours. The microstructures and morphologies of these coatings were examined by X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscope, in association with adhesion strength measurement, residual stress measurement and potentiodynamic polarisation with 3.5% NaCl and 10% H2SO4 solutions. Results show that the solid solution hcp-(Cr,Al)N phase of as-deposited AlCrN coatings decomposes into hcp-AlN and CrN phases, then further decompose into N and Cr with increasing annealing temperature. Metal particles and droplets on the coating surface were gradually removed simultaneously when compared with as-deposited coatings. The highest adhesion strength was obtained after annealing at 700 °C. It decreased with increasing annealing temperature due to the σ-FeCr phase and Cr2N phases, and the residual stress decreasing. The potentiodynamic polarisation
