“…During the deposition process, some droplets of Al or Cr were generated and solidified before they arrived at the substrate resulting in the formation of macro-particles. The macro-particles possess larger specific area than the coating around them, and they shrink obviously at the ambient temperature after the deposition, which might be flaked from the surfaces resulting in the pits and pinholes left on the coatings [23,24]. From the CrAlN1# coating to CrAlN4# coating, the diameters of the maximum macro-particles increase gradually.…”

Four CrAlN coatings with various Al content were prepared by arc ion plating technology under different target currents. The effect of the Al content on the microstructure, chemical compositions, element chemical bonding states and mechanical properties of the CrAlN coatings was analyzed. X-ray diffraction results show that the primary phase of the CrAlN coating is fcc-(Al, Cr)N when the Al content is about 44.02 at.%. However, when the Al content increases to about 53.34 at.%, hcp-AlN phase emerges in the coating. And the hcp-AlN phase becomes the main phase in the CrAlN coating with Al content of about 69.55 at.%. Cross-sectional images show that all the four coatings possess dense structures and the deposition rate of Al atom is higher than that of Cr atom. The hardness of the CrAlN coating with Al content about 44.02 at.% is the largest (3149.72 HV) due to the solid solution hardening effect of the Al element. When the hcp-AlN phase is generated in the CrAlN coating, the hardness declines. The tribological experiment shows that the wear resistance of the CrAlN coating decreases gradually with increasing Al content when sliding against 100Cr6 steel ball.

“…The load-bearing capability is reinforced by the increasing of dislocation densities. It is believed that high dislocation densities enhance the resistance to the growth of wear cracks from the surface into the coating [38]. Under these circumstances, wear mechanism of the M-CrN coating is the adhesive wear.…”

“…), the chromium nitride (CrN) coatings not only have high hardness, good wear resistance, and chemical inertness, as well as superior oxidation resistance up to 700 °C, but they also can relatively easily achieve relatively high thickness without the stress problem, which have been rapidly developed by some PVD techniques in recent years including arc ion plating (AIP), ion beam assisted deposition, magnetron sputtering, and so on. − ,,, Lin et al have successfully fabricated thick and dense CrN/AlN superlattice coatings (up to 10 μm) with good adhesion and superhardness by the modulated pulse power magnetron sputtering technique . Compared with other deposition technologies, arc ion plating (AIP) technology is an outstanding method and preferred by industrial produce for hard coating due to the high ionization ratio, high deposition rate, flexibility of target arrangements, and merits of producing coating with good coating–substrate adhesion. , Shan et al reported that Cr/Cr 2 N/CrN multilayer coating synthesized by multiarc ion plating with a thickness of 24.4 μm exhibited good anticorrosion and tribological performances .

However, these approaches are not always commercial uses because of the local compositional and microstructural nonuniformity within the coatings.…”

Continuous growth of traditional monolayer CrN coatings up to 24 h is successfully achieved to fabricate ultrathickness of up to 80 μm on the 316 stainless steel substrate using a multiarc ion plating technique. The microstructures, mechanical properties, and tribological properties evolution with the CrN coating continuously growing was evaluated in detail. The transmission electron microscopy observations and inverse Fourier-filtered images reveal a relaxation mechanism during the continuous growth of CrN coating, which can lead to a decrease in the residual stress when coating growth time exceeds 5 h. The scratch test and friction test results both show that the load-bearing capacity of coating is significantly increased as CrN coatings growing thicker. During the scratch test, the ultrathick CrN coating of thickness 80.6 μm is not failed under the load of 180 N, and the dominant failure mechanism is the cohesive failure including wedge spallation and cracking. The dry-sliding friction test results show the mean coefficient of friction and the wear rate of ultrathick CrN are respectively decreased by 17.2 and 56.8% at most compared with the thin coating (thickness is 5.4 μm). The ultrahigh load-bearing capacity and excellent tribological property are attributed to the relaxation mechanism and limited contact pressure as the coating grows continuously.
