“…Sui et al 14 informed that the titanium-based nano-composite coatings have high hardness, reduced wear and improved tool life. 15 Dhar et al 16 investigated the uncoated cutting tool inserts on cryogenic conditions and found reduced wear and increased tool life. The cutting tools insert with titanium-based elements with PVD-CVD hybrid coatings gives increased tool life in milling operations.…”

Tool life and wear of the coated cutting tools insert play an important role on turning EN24 steel. On turning EN24 steel it is very essential to find the optimum range of coating thickness on the cutting tool inserts with increased tool life and reduced wear. This article investigates the performance evaluation of TiAlSiN-PECVD multilayer nano-coated cutting tool inserts with different coating thicknesses of 1.5, 3, 5, 6.5, 8, 10 and 12 μm.The performance of the cutting tool inserts were evaluated with a cutting speed of 47.12, 54.97 and 62.83 m/min on turning EN24 work material. In the experimental study, the cutting tool inserts with coating thicknesses of 5, 6.5 and 8 µm has given increased tool life and reduced wear where as the coating thicknesses of 1.5, 3, 10 and 12 µm has given reduced tool life and increased wear. The minimum tool wear of 0.124 mm occurred in the coating thickness of 6.5 µm with a cutting speed of 55 m/min. It is observed that the coating thickness ranges from 5 μm to 8 μm has produced an enhanced tool life with corresponding Vickers hardness values ranging from 2400 to 2440 HV. In the comparative study, it has been found that the experimental tool life has enhanced by 19.18%, 31.60% and 20.18% for the corresponding coating thicknesses 5, 6.5 and 8 µm respectively when compared with their theoretical tool life.

“…Hybrid PVD-PECVD process of titanium sputtering process is used to prepare metal-carbon nanocomposites [8]. In the PVD method of TiAlN coated cutting tools, it is seen that they have less wear resistance than uncoated cutting tools [9]. In the process of the PECVD method of coatings with the material SiCN, the nano hardness and elastic modulus in the intermediate temperature between 300°C and 700°C are 30 GPa and 219 GPa respectively when compared to the PVD, CVD coatings which have the values of 13 GPa and 116 GPa respectively.…”

Tool life of the traditional cutting tools is comparatively lesser on machining the martensitic stainless steel AISI 416 which is one of the hardest materials. In order to increase the tool life, wear-resistant nanocoatings on the cutting tools have been explored. This study enunciates a comparison of tool life between PECVD (plasma-enhanced CVD multilayer nanocoated) and PVDMNC (PVD multilayer nanocoated) cutting tools on turning a martensitic stainless steel AISI 416 by experimental and theoretical investigations in addition to exploration of the machinability studies of cutting tool flank wear, tool hardness and surface roughness of work material. An orthogonal design, signal-to-noise ratio and Analysis of Variance (ANOVA) methods were employed to confirm the parameters like cutting speed, tool hardness and feed rate that are involved in the study to estimate the cutting toollife. The investigations confirmed that cutting speed was the most dominant factor in determining tool life while comparing with other parameters. It was observed from the ANOVA results that the cutting speed, tool hardness, and feed rate have contributed 41.44%, 33.79%, and 24.35% respectively in determining the tool life of PECVD cutting tools whereas the contributions of the same parameters were found to be 40.01%, 32.90%, and 26.63% respectively for PVDMNC cutting tool. It is evident from the results that the cutting performance of the PECVD cutting tool is superior in terms of cutting speed and hardness which were enhanced by 1.43% and 0.89% respectively in addition to lesser wear rate when compared to the performance of PVDMNC cutting tools.

Tungsten (W) was coated onto a silicon (Si) anode at the nanoscale via the physical vaporization deposition method (PVD) to enhance its electrochemical properties. The characteristics of the electrode were identified by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis, and electron probe X-ray microanalysis. With the electrochemical property analysis, the first charge capacities of the W-coated and uncoated electrode cells were 2558 mAh g− 1 and 1912 mAh g− 1, respectively. By the 50th cycle, the capacity ratios were 61.1 and 25.5%, respectively. Morphology changes in the W-coated Si anode during cycling were observed using SEM and TEM, and electrochemical characteristics were examined through impedance analysis. Owing to its conductivity and mechanical properties from the atomic W layer coating through PVD, the electrode improved its cyclability and preserved its structure from volumetric demolition.
