Gradient CrCN cathodic arc PVD coatings

Vapour deposition technologies for the fabrication of hot-forming tools: a review

“…This is due to the low tendency of CrN to stick to the working material during processes requiring high contact stresses at the tool/material interface. At present, recently developed CrCN [12] coatings are found to exhibit even lower adhesive COF to those of CrN when sliding on stainless steels. AlCrN [2,13] coatings have only reached the market in the last decade.…”

“…PVD and CVD permit the design of a variety of film architectures with the aim to outperform the protective characteristics of single-layer configurations. Figures 1a-c show different multilayer structures developed using the cathodic arc PVD technique; (a) a gradient CrCN coating [12], (b) a nitride/ nitride nanomultilayered TiN/CrN arc evaporated film (c) and a nitride/oxide multilayered CrAlN/CrAlO arc evaporated coating. Gradient composition films containing a hard layer at the interface and a low COF outer layer is a welldeveloped solution for several applications in the manufacturing sector [13,29].…”

Comparison of crack resistance between ternary CrSiC and quaternary CrSiCN coatings via nanoindentation

“…However, Fuentes et al [29] and Warcholinski's group [30][31][32][33] pointed out that the residual stress of CrCN coatings was more intensive than CrN coatings, as well as rougher surface. On the other hand, higher density of surface particle, more defects and worse adhesion of TiCN coatings after C doping were reported in Refs.…”

Structural and mechanical properties of compositionally gradient CrNx coatings prepared by arc ion plating

“…Suresh et al [3] demonstrated by means of experimental and computational results, that a controlled gradient in elastic modulus alone can result in a significant enhancement in the frictional sliding resistance. Relative researches on TiAlN gradient coatings [4][5][6][7] and C-gradient CrCN coatings [8] reveal that gradient coatings exhibit superior adhesion properties as compared to single layer coatings. As to Cr-N coatings, many efforts have been devoted to CrN x coatings deposited with fixed N 2 flux ratio values [9][10][11][12][13][14].…”
