“…This finding also corresponded to the hardness, and scratch test results that the TiAlN provided relatively high hardness and high damage threshold for Lc1 to Lc3 (Figure 4(c)), hence preventing the coated tool from wear. Although the AlCrN-coated tool can promote better wear and crack resistances than TiAlN as reported in the study of Fox-Rabinovich et al, 4 the wear rate of this coating material was found to be higher than TiN and TiAlN in this study as well as Vettivel et al’s 19 work. As per Figures 6 and 7, the wear land on rake face was found to be much larger than the flank face.…”

This article presents a comprehensive analysis of surface characteristics and drilling performance of uncoated and coated tungsten carbide drills. The single- and double-layer coatings of TiN, TiAlN and AlCrN were examined in terms of surface roughness, microhardness and crack resistance. In addition, drilling torque and thrust force were experimentally measured and compared to the developed models based on the drilling mechanics and drill geometries. Tool wear and hole surface roughness were also considered to assess the machining performance of different coated tools. The results revealed that all coated drills can offer better cut surface quality, 28% lower cutting loads and longer tool life than the uncoated drills. Although AlCrN was found to be the hardest coating material among the others, it caused large wear on the cutting edges and poor surface roughness of produced holes. The lowest torque and thrust force were achievable using TiN-coated drill, while the use of TiAlN coating resulted in the lowest surface roughness and smallest tool wear. Furthermore, the drilling torque and thrust force model developed in this study were found to correspond to the experimental measures with the average error of 8.4%. The findings of this work could facilitate the selection of coating materials to advance the machining performance.

“…However, Cr 2 O 3 /TiAlN coating witnessed lesser pits and microdroplets, indicating the uniform distribution of coating Previous studies suggest that a decrease in the surface roughness is attributed to reducing grain size, sample bias, and substrate temperature during deposition of the coating. 35,36 In addition, Patnaik et al 37 suggested that nitrogen pressure during deposition is one of the factors that influence the surface quality.…”

TiAlN film was deposited on Cr2O3‐coated plasma‐nitrided DAC‐10 tool steel to obtained multilayer Cr2O3/TiAlN coating layer using cathodic arc deposition technique. The structural make‐up of the coating was characterized using Atomic Force Microscopy (AFM) and X‐ray diffraction methods, and the mechanical properties were evaluated using nanoindentation and nanoscratch test. The structural phases of the coating indicated the presence of crystalline CrO structure and cubic TiAlN phases. The coating showcased improved hardness (38 GPa), elastic modulus (387 GPa), and adhesion along with appreciable H/E (0.09) and H3/E2 (0.366 GPa) attributes. Further, friction‐induced wear behavior of the coating was investigated against steel and Al2O3 counterbodies under dry sliding conditions. The wear behavior of the coating was greatly influenced by its hardness and deformation properties and frictional behavior of the counterbodies. More spikes and fluctuation were observed in the frictional curve against Al2O3 counterbody attributed to the emanation of TiO2, Cr2O3, and Al2O3 compounds due to dry sliding leading to the formation of flakes and delamination induced debris. Against the steel counterbody, the coating mainly formed a typical smooth glossy surface ascribed to the formation of Fe2O3 compound on the worn surface.

“…The fundamental aim of coating application in these fields is to provide low friction coefficients (COFs) to decrease energy losses 8 and increase the wear and corrosion resistance 9,10 to extend the effective life of metal components. 11 Hence, TiAlN, AlTiN, 12 and AlCrN, TiN, 13,14 TiZrN, ZrN, TiCN 15 coatings are used to increase the wear resistance of tool steel for a cost-effective lifetime which is used in dies (stamping or extrusion), cutting, mold making, or impact applications like a hammer. 16,17 On the other hand, Cr and CrN are the most popular coating types used as piston ring coating and diamond-like carbon (DLC), 18–20 and TiN and SiN coatings 21 are also used in valve train system of ICEs to protect steel or cast iron piston ring surface from wear and corrosion generated by combustion products.…”

Copper beryllium (CuBe) with good mechanical and high electrical conductivity properties is used in metalworking, electronic devices, automotive systems, and aerospace systems. Having low hardness limits its usage in tribosystems such as internal combustion engine valve train systems. In this study, heat-treated CuBe material was coated with CrN under a micron thickness by cathodic arc physical vapor deposition (arc-PVD) to improve wear resistance not only at unlubricated condition but also at the lubricated condition for tribosystem, especially a material candidate for cam tappets. Therefore, CrN-coated CuBe, CuBe, and AISI52100 steel samples were tested by a tribometer at unlubricated and lubricated sliding conditions. Surface morphological changes and tribochemical formation were investigated by optical microscope, optical profilometer, atomic force microscope, and scanning electron microscope. The results showed that CrN increased the wear resistance of the CuBe significantly, and it can be used as cam tappet material both on unlubricated and boundary lubrication regimes.
