“…In our determination, in the HLPD mode, these peaks appear at 1362 and 1568 cm −1 , respectively; therefore, we can conclude that we find good agreement with the previously reported data. There were some alternative potential causes [ 9 , 20 , 41 ] for the occurrence of the dominant D- and G-bands in the Raman spectra of the 211 films. In [ 41 ], it was suggested that carbon clusters of quite large dimensions might have preferential orientation, and in [ 20 ], it was inferred that the whole high-spectral region encountered in the Raman spectra can be assigned to diamond-like carbon clusters having large grain boundaries made of sp 2 -bonded carbon.…”

“…In its bulk form, or subjected to sintering procedures, this system was investigated for other industrial domains [ 17 ]. Some authors studied the effect of changing the synthesis parameters onto the films’ tribology and oxidation behavior [ 18 , 19 , 20 ], while others considered the influence of ion beam annealing onto films of Cr-Al-C [ 21 ].…”

The microcrystallization effects induced by the real-time laser annealing in Cr-Al-C ion-sputtered films with an off-stoichiometric composition are studied. The laser annealing has been performed during Raman experiments with tunable laser power densities. Morphostructural changes induced during laser annealing were investigated by scanning electron microscopy. It has been proven that real-time laser annealing in the high-laser-power-density mode promotes quite clearly the formation of nanograins through surface microcrystallization. Detailed Raman analysis allowed for the observation of the optical modes that unequivocally identifies the low-symmetry 211 MAX phase in both low- and high-power-density modes. Such findings confirming the microcrystallization as well as the stabilization of the grain boundaries by carbon nanoclustering are confirmed by X-ray diffraction results, where the single-phase hexagonal 211 was unequivocally proven to form in the high-laser-power-density mode. The microcrystallization via laser annealing was also found to be beneficial for the elastic behavior, as the hardness values between 16 and 26 GPa were found after laser annealing, accompanied by a significantly high Young’s bulk modulus. Such large values, larger than those in bulk compounds, are explicable by the nanometric grain sizes accompanied by the increase of the grain boundary regions.

“…During physical vapor deposition (PVD), single or multiple source materials are evaporated or sputtered in a high vacuum . Subsequently, the formed atoms, molecules, or ions are transferred to the surface of substrate, leading to the nucleation and growth of a thin film . Although PVD is classified as physical method, some reactions with the materials surface may still take place to facilitate the growth of film.…”

Thanks to a considerable number of fascinating properties, titanium (Ti) and Ti alloys play important roles in a variety of industrial sectors. However, Ti and Ti alloys could not satisfy all industrial requirements; the degradation of Ti and Ti alloys always commences on their surfaces in service, which declines the performances of Ti workpieces. Therefore, with aim to further improve their mechanical, corrosion and biological properties, surface modification is often required for Ti and Ti alloys. This article reviews the technologies and recent developments of surface-modification methods with respect to Ti and Ti alloys, including mechanical, physical, chemical, and biochemical technologies. Conventional methods have limited improvement in the properties and/or restriction on the geometry of workpieces. Therefore, many advanced surfacemodification technologies have emerged in recent decades. New methods make Ti and Ti alloys have better performance and extended applications. With requirement of high surface properties in future. Understanding the mechanism in various surface-modification methods, combining the advantages of current technologies and developing new coating materials with high performance are required urgently. As such, incorporation of different surface-modification technologies with high-performance modified layers may be the mainstream of surface modifications for Ti and Ti alloys. . His current research interests focus on the metal additive manufacturing (e.g., selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructureproperties in high-performance materials.

“…On the other hand, gradient and multilayered coatings composed of different nitride layers show superior mechanical strength, such as hardness and wear resistance, as compared to mono-layered coatings due to their specific interfaces [19]. For this reason, many studies on multilayer coatings have been conducted [19]- [24].…”

In this study, a carbonitride coating film was deposited on a cemented carbide ISO K10 using three different Al-Cr-W-Si targets. The coating film structure consists of mono-layer film and multi-layer films. The hardened steel ASTM D2 was cut with five types of coated cemented carbide tools. The tool wear of the coated tools was experimentally investigated. The following results were obtained: (1) Comparing the wear progress of the (Al53,Cr23,W14,Si10)(C,N)-and (Al58,Cr25,W7,Si10)(C,N)-coated tool, the wear progress of the (Al58,Cr25,W7,Si10)(C,N)-coated tool is slightly slower than that of the (Al53,Cr23,W14,Si10)(C,N)-coated tool. (2) Comparing the wear progress of the (
