“…Probably the most common analysis in the decorative industry for PVD coatings is thickness determination [156]. Thickness is an important parameter, and it is correlated with other properties like adhesion, wear and corrosion resistance, and barrier properties [157,158]. The importance of layer thickness is amplified in modern multilayer systems, as their properties depend on the interface volume between layers [159,160].…”

Physical Vapor Deposition (PVD) is a widely utilized process in various industrial applications, serving as a protective and hard coating. However, its presence in fields like fashion has only recently emerged, as electroplating processes had previously dominated this reality. The future looks toward the replacement of the most hazardous and toxic electrochemical processes, especially those involving Cr(VI) and cyanide galvanic baths, which have been restricted by the European Union. Unfortunately, a complete substitution with PVD coatings is not feasible. Currently, the combination of both techniques is employed to achieve new aesthetic features, including a broader color range and diverse textures, rendering de facto PVD of primary interest for the decorative field and the fashion industry. This review aims to outline the guidelines for decorative industries regarding PVD processes and emphasize the recent advancements, quality control procedures, and limitations.

“…Tool coating also improves tool resistance to wear and adhesion, allowing for longer tool service life and higher-speed machining applications [ 7 ]. Having excellent performance, coated tools are widely used to cut various materials [ 8 , 9 , 10 ], accounting for 80% of the total tool count. Among them, Ti 1-x Al x N-coated tools are widely used in titanium alloy machining [ 11 , 12 , 13 ] due to their high heat resistance, superior chemical resistance, and low friction coefficient [ 14 , 15 ].…”

Ti1-xAlxN coating is formed by replacing some Ti atoms in TiN with Al atoms, and their properties are closely related to Al content (0 < x < 1). Recently, Ti1-xAlxN-coated tools have been widely used in the machining of Ti-6Al-4V alloy. In this paper, the hard-to-machine material Ti-6Al-4V alloy is used as the study material. Ti1-xAlxN-coated tools are used for milling experiments. The evolution of the wear form and the wear mechanism of Ti1-xAlxN-coated tools are studied, and the influence of Al content (x = 0.52, 0.62) and cutting speed on tool wear are analyzed. The results show that the wear on the rake face changes from the initial adhesion and micro-chipping to coating delamination and chipping. Wear on the flank face varies from the initial adhesion and grooves to boundary wear, build-up layer, and ablation. The main wear mechanisms of Ti1-xAlxN-coated tools are dominated by adhesion, diffusion, and oxidation wear. Ti0.48Al0.52N coating protects the tool well and extends its service life.

“…Thick TiAlN coating reduces heat dissipation into the tool body as compared to thin coating; hence chip temperature increases with thicker TiAlN coating. 6 Poor surface quality (surface roughness) of component is the most common major problem that occurs during the turning process of In718. 7 Different techniques are used to improve surface roughness in the turning operation of In718 such as the use of cutting fluid, flood cooling, minimum quantity lubrication (MQL), 8,9 MQL with nanoparticles, 10 cryogenic, 11 and compressed air (oxygen and nitrogen) cooling, 12 heat treatment etc.…”

This study examined the effect of magnetic field with single point coated‐carbide tool during turning process of Inconel718 (In718). After the turning process, tribological properties (surface roughness and tool wear) and chip morphology were analyzed. Two cylindrical Neodymium (N52) grade permanent magnets are used to apply the magnetic field during the machining. Cutting speed and magnetic field intensity along with constant feed and depth of cut are used to analyze tribological properties along with chip morphology. Experimental results show that 80 m/min cutting speed and 426 Gauss magnetic field has the best results in term of lowest surface roughness and tool wear. Lorentz forces developed due to the applied external magnetic field help to improve surface roughness compared to nonmagnetic field machining. Developed fine particles during the turning process get repulsed in case of magnetic field machining which helps to improve tool wear.
