Characterization of TiZrN and TaZrN Nanocomposite Multilayer Coating Deposited via RF/DC Magnetron Sputtering on AISI4140 Steel

Abstract

In this present research work, TiZrN and TaZrN multilayer coating was deposited on 4140 steel by RF/DC magnetron sputtering for comparative work also prepared in single layer. The flow rate ratio of Ar/N2 was set to 15 : 3 sccm and the thin film was prepared by the PVD (physical vapor deposition) method by RF/DC magnetron using a Ti-Zr and Ta-Zr target with a purity of 99.99%. The crystal structure, surface morphology microstructure, and component arrangements were explored by X-ray diffraction (XRD), scanning electron microscope (SEM), and atomic force microscopy (AFM). It has been found that the crystal structure, surface morphology, microstructure, and elemental composition of the membrane are strongly dependent on deposition parameters. It is mechanically characterized by corrosion and Vickers hardness. In AFM measurements, coarse cluster particles with increasing Ti and Ta values not only increase the average roughness (Ra) by 2.341 nm (200°C) and 2.951 nm (400°C) but also have a continuous average thickness which was shown to increase by 1.504 nm and 781.75 nm. With the increase of hardness, the roughness decreases correspondingly. The TiZrN multilayer microhardness augmented to 314 GPa at 200°C and 371 GPa for TaZrN (400°C).

“…It is not necessary to stress the significance of clean air in maintaining a decent and healthy lifestyle. As a result, emissions must be significantly reduced in order to preserve a relatively secure planet for future generations [1][2][3][4][5][6][7].…”

Enhanced Corrosion Resistance of TiZrN-Coated Additively Manufactured 8620 Low-Alloy Steel in Nitrate Salt Solution and Salt Bath

“…High-purity argon gas was supplied to the chamber and the sputtering was carried out at a working pressure of 1.2 × 10 −2 Torr. The substrates were heated to a temperature of 200 • C. A substrate temperature of 200 • C was chosen to improve coating adhesion [52], increase hardness [53], and reduce residual stress [52] and dislocation density [54]. The Ti and Zr targets were co-sputtered via DC and RF guns powered at 150 W and 100 W, respectively.…”

Aquatic Emission and Properties Analysis for Wind Turbine Blades

“…Tiny cracks start as a result of material fatigue and spread out as a result of cyclic stress. e repetitive, cyclic character of the stressing can lead to breakage and collapse even when the load applied is lower than the material's compressive properties [15,16]. Dynamic and steady-magnitude fatigue loads are the two types of fatigue loads.…”
