“…Due to the grain boundaries in crystalline coatings promoted the propagation of cracks, amorphous Zr-Cu-O coating with high Cu content of 38 at.% exhibited better fracture toughness as compared to the polycrystalline coatings. In addition, the additive Cu as a soft and ductile metal has been reported to improve the coating hardness and tribological properties of (Ti,Al)N-Cu coatings [27]. Thus, it can be inferred that the comprehensive properties of Ti-Al-V-N multicomponent coatings could be improved by the addition of Cu to form a nanocomposite structure.…”

“…Based on the value shown in Figure 7, the ration H 3 /E 2 (H for coating hardness while E for coating elastic modulus) of CrN and TiN coating is 0.405 and 0.169, respectively. This indicated that the TiN coating has higher plastic deformation resistance than the CrN coating [20][21][22][23].…”

Coatings of 3 μm CrN and TiN were prepared by a magnetic filtered cathodic vacuum arc process (MFCVA) on Ti-6Al-4V substrates, respectively. Rotating bending tests and uniaxial tests were conducted for investigating the effect of the thin and uniformly distributed hard CrN and TiN coatings on the fatigue and mechanical properties of Ti-6Al-4V substrate. During both tests, no coating spallation phenomenon was observed, which indicated that the hard coating bound well with the substrate. The fatigue test results showed that the fatigue strength of the coated sample was decreased in both the low- and high-cycling fatigue regimes compared with the uncoated Ti-6Al-4V substrate. Compared with the TiN coating, the CrN coating caused a more significant reduction on the fatigue property of the uncoated Ti-6Al-4V substrate due to its inferior plastic deformation capacity. Furthermore, the tensile test results showed that the coated sample had a relative higher ultimate strength, yield strength, and lower elongation compared with the uncoated Ti-6Al-4V substrate. This may be due to the fact that the hard coating could suppress the initiation of cracks, and so higher stress was needed for crack initiating. During the crack propagation period, the hard coating cracked at a relative higher velocity, which led to cracking of the ductile substrate and elongation reduction.

“…Therefore, the development of hard and tough coatings has become the objective of researchers [9][10][11]. Many studies have focused on the crack resistance modification of transition metal nitride coatings by tough metal incorporations, such as Ni [12,13], Cu [14], Ag [15,16], Au [17], Al [18], Nb [19], Ti/Al [20], and Cu/Cr [21]. As a result, the wear resistance of transition metal nitride coatings was enhanced accordingly [13][14][15].…”

“…However, the toughening degree among different tough metals in Refs. [12][13][14][15][16][17][18][19] is incomparable since these tough metals were not compared simultaneously in one article and the hardness decrement was not considered. Namely, it is difficult to distinguish which tough metal exhibits a superior synthetic strengthening effect.…”

Comparison of mechanical and tribological properties of CrBN coatings modified by Ni or Cu incorporation

To compare the merits of Ni and Cu, the mechanical and tribological properties of CrBN coatings modified by Ni or Cu incorporation were studied. The results demonstrated that the CrBN-Cu coatings presented a lower friction coefficient than CrBN and CrBN-Ni coatings owing to the improved lubrication effect of the CuO layer originating from the tribochemical reaction. However, the hardness decline due to Cu incorporation was much greater than that of Ni incorporation. Thus, the CrBN-Cu coatings exhibited a higher wear rate than the CrBN coating. In contrast, the plastic deformation enhancement induced by Ni incorporation exceeded the hardness decline. Therefore, the wear of CrBN-Ni coatings partially turned to plastic deformation to present a lower wear rate than that of the CrBN coating.
