“…The strongest diffraction peaks of the three coatings were partially overlapped diffraction peaks of the fcc-CrN and fcc-AlN grains when 2θ was 43.7 • and 43.9 • , and both grew along the (200) crystal plane. Moreover, the diffraction peak intensity of the AlCrSiN/AlCrSiON duple coating was significantly reduced, which may be due to the increase in internal stresses between the two coatings, leading to a distorted crystal structure, and structural defects could also cause the decrease in the diffraction peak intensity [14]. In addition, the fcc-CrN diffraction peaks on the (111) crystal plane at 2θ = 37.5 • were detected for all the coatings, and the peak intensities of the AlCrSiON coating and AlCrSiN/AlCrSiON duplex coating were significantly lower than that of the AlCrSiN coating.…”

“…If it is applied to coating protection, namely introducing an appropriate amount of oxygen during the coating process, the oxidation resistance and thermal stability of the resulted coatings are expected to be improved by forming an oxide barrier. Ahmad [14] et al developed the AlCrN/AlCrON duplex coatings and optimized the oxygen flow rate for the preparation of an AlCrON top layer. The coating deposited under the oxygen flow rate of 150 sccm presented the best phase structure stability with solid solution fcc-(Cr,Al)ON phase at 700 • C. Meanwhile, the minimum friction coefficient of 0.52 and the lowest wear rate of 1.57 × 10 −16 m 3 /(N•m) were obtained during wear tests at a high temperature.…”

Aluminum rich nitride coatings are often used to protect cutting tools and prolong their service life. In this work, a preoxidation technique and duplex coating design were combined to further improve the bearing capacity and heat resistance of cutting tools. The Al-Cr-Si-N, Al-Cr-Si-O-N, and Al-Cr-Si-N/Al-Cr-Si-O-N duplex coatings were developed by arc ion plating, respectively. The morphology, phase constituents, mechanical and tribological properties of the coatings were characterized and tested by SEM, XRD, a micro-hardness tester, scratch tester, and tribometer. The results showed the coating became more compact and smoother after oxygen doping. However, the Al-Cr-Si-N coating presented the best mechanical properties and tribological behaviors. Its hardness and critical load showed the highest values, which were about 4000 HV and 81 N, respectively. A friction coefficient of 0.67 and wear rate of 1.4 × 10−3 μm3/N·mm were also the lowest values in the study. The three coatings were deposited on the same solid carbide end mills and performed the cutting tests under same conditions. By comparison, the Al-Cr-Si-N coated tool presented the longest tool life and minimum cutting force when cutting C1045 medium-carbon steel. After 90 min of dry milling, the width of the flank wear band (VB) of the AlCrSiN coated tool reached 135 μm, which was much lower than that of the other two coated tools.

TiN, TiAlN and TiSiN coatings were deposited on the W6Mo5Cr4V2 steel substrate by hollow cathodic-assisted multi-arc ion plating technology. The tribological properties of these coatings are comparatively studied. The microstructure, element composition, nanomechanics and wear properties of the substrate and coating surface of high-speed steel were evaluated by XRD, SEM, EDS, TEM, XPS and nano-indentation test. The results show that the mechanical properties of ternary coating TiAlN and TiSiN are improved compared with high-speed steel and binary TiN coatings, with TiAlN hardness and elastic modulus of 44.8 GPa and 438.6 GPa, and TiSiN hardness and elastic modulus of 34.8 GPa and 333.2 GPa. TiAlN coating has the strongest ability to resist plastic deformation due to solid solution strengthening. TiSiN can improve the plasticity and toughness of hard coating after fine grain strengthening. There is a strong correlation between the amount of sample wear and H3/E*2 value, and the larger the H3/E*2 value, the higher the wear resistance of the sample. The surface friction coefficients of TiN, TiAlN and TiSiN were all small compared with high-speed steel, and the roughness at the wear tracks of high-speed steel increased, while the roughness at the wear tracks of the coating samples decreased.
