“…All of the AlTiN coatings exhibited sufficient adhesion strength. The slightly lower adhesion strength of the AlTiN-Ni and AlTiN-Cu coatings can be attributed to their higher MP contents, which results in decreased surface roughness [27]. Surface defects in metallic macroparticles (MPs) are inevitable when cathodic arc evaporation deposition technology is used, and they often cause the properties of the coatings to deteriorate [25,26].…”

In this study, three kinds of coatings, AlTiN, AlTiN–Ni, and AlTiN–Cu were deposited via the cathodic arc evaporation method. The microstructure, mechanical properties, oxidation resistance, and cutting behavior of these coatings were then investigated. The incorporation of Cu(Ni) into AlTiN eliminated its columnar structure and led to an increase in the growth defects of its macroparticles. The addition of Cu and Ni decreased the hardness of the coatings, their elastic moduli, and their friction coefficients. All of the AlTiN, AlTiN–Ni, and AlTiN–Cu coatings presented sufficient adhesion strength values. The oxidation resistance of these three coatings was determined to be in the following order: AlTiN > AlTiN–Ni > AlTiN–Cu. Titanium turning experiments indicated that the cutting force was reduced and the tool life was improved through doping with Cu(Ni) elements, dependent on cutting speed. The AlTiN–Ni coating showed the best performance at a high cutting speed, whereas the AlTiN–Cu coating was more successful at a lower cutting speed.

“…[1][2][3][4] Owing to the high melting point and hardness, WN coatings have a wide range of applications in mechanical components, cutting tools and human orthopaedic implants. 5,6 In addition, the coatings have a better frictional behaviour because W can react with the oxygen/ moisture in the air and form Magnéli phase (WO 3 ) during the wear test. 7,8 However, the applications of WN coatings have been largely hindered by their relatively limited oxidation resistance.…”

W-Y-N coatings with yttrium content ranging from 0 to 8.2 at.-% were deposited by reactive magnetron sputtering technique. The influence of yttrium content on the structure, oxidation resistance and mechanical properties was investigated. The results show that yttrium atoms substitute tungsten atoms forming the solid solution W-Y-N coatings. All the coatings exhibit a single-phase face-centered cubic structure and the preferred orientation changes from ( 200) to ( 111) with yttrium addition. The grain size of W-Y-N coatings decreases with the increase of yttrium content. The oxidation resistance temperature of W-Y-N coatings increases from 500°C at 0 at.-% Y to 730°C at 8.2 at.-% Y. All coatings are in compressive stress state. The hardness, elastic modulus and compressive stress of W-Y-N coatings increase gradually from 28.0, 320 and 1.1 GPa at 0 at.-% Y to 36.0, 385 and 2.1 GPa at 8.2 at.% Y, respectively. The improvement of hardness was attributed to the effect of solid solution strengthening and the grain refinement. In addition, the addition of yttrium content into WN coating also improves its resistance against elastic strain and plastic deformation to failure.

“…Hard nitride coatings have limited applications due to their poor toughness, regardless of their excellent hardness and wear resistant properties [1][2][3][4][5][6]. Researches on increasing the toughness of hard nitride coatings while maintaining their hardness has attracted considerable attention globally [7,8]. Currently, nitride coatings have been toughened via the ductile phase, gradient and multilayer structures, phase transformations, and nanocrystalline structures [9][10][11][12].…”

“…In recent years, MeN-Ni series of soft-phase coatings have increasingly attracted attention [17][18][19][20][21][22]. Yang et al doped different contents of nickel (Ni) into tungsten nitride (WN) and found that, with an increase in the Ni content, the hardness of the coatings first increased and then decreased; when the Ni content was sufficiently high, the soft Ni phase increased and hard phase decreased, showing a decreased hardness and enhanced toughness [8]. Karvankova et al found that a small amount of Ni doping into Zr-N could improve the hardness and result in preferential growth along the NaCl (200) plane [19].…”

This study determines the effects of nickel (Ni) doping on the composition, phase structure, chemical valence state, hardness, and toughness of CrAlNiN coatings. CrAlNiN coatings with various Ni contents (0.00 at%-27.71 at%) were deposited on the surfaces of M2 tool steel and monocrystalline silicon (Si) using unbalanced magnetron sputter ion plating. The results showed that the CrAlNiN coatings possess a nanomultilayer structure, maintaining the face centered cubic crystal structure of the chromium aluminum nitride (CrAlN) coatings. The Ni in the coatings acts as a toughening phase to ease stress, to increase resistance to crack growth, and to delay the generation of cracks, thereby having an obvious toughening effect. At an Ni content of approximately 20.33%, the Ni toughening phase in the modulation layer tends to saturate and the effect of continuing the increase in Ni content is limited from the viewpoint of improving the toughness.
