“…When compared to TiN, the TiAlN (111) peak exhibited a slight shift to higher angles, possibly due to the incorporation of aluminium-based lattice mode Furthermore, the intensity of the (200) peak in TiAlN is higher than the (111) peak same sample but lower than that of TiN. In the TiAlN sample, minor peaks correspo to TiN's (220) plane are close to the AlN cubic (220) plane, while the h-AlN (002) peaks at 36.6° [51,53,54]. Furthermore, hexagonal TiAlN phases were discovered o (202) and (206) planes, the latter of which could be related to the alumina phase o (220) plane at 79.5° [51,55].…”

This study investigates the mechanical properties, surface integrity, and chemical configuration of PVD-coated high-speed steel (HSS) cutting tools, with a particular focus on titanium nitride (TiN) and titanium aluminium nitride (TiAlN) coatings. A range of characterisation methodologies were employed to examine the impact of pre-coating surface conditions on the resulting coatings. This impact includes the effects of gas bubble production and unequal distribution of elements, which are two unwanted occurrences. Notwithstanding these difficulties, coatings applied on surfaces that were highly polished exhibited more consistency in their mechanical and elemental characteristics, with a thickness ranging from 2 to 4 µm. The study of mechanical characteristics confirms a significant increase in hardness, from an initial value of roughly 1000 HV0.5 for untreated tools to 1300 HV0.5 for tools with physical vapour deposition (PVD) coatings. Although PVD coatings produced on an industrial scale might not exceed the quality of coatings manufactured in a laboratory, they do offer substantial enhancements in terms of hardness. This study highlights the significant importance of thorough surface preparation in achieving enhanced coating performance, hence contributing to the efforts to prolong the lifespan of tools and enhance their performance even under demanding operational circumstances.

“…The XRD patterns of the coatings are shown in Figure 4 . In the XRD profile of the coatings, A indicates CrN(111), AlN(102), CrN(220), AlN(112) and AlN(104) [ 26 , 27 ]. The dominant orientation of hexagonal crystal structure AlN(102) was a grain size of 5.8 nm, and for CrN(111) it was a grain size of 6.3 nm.…”

Effect of AISI H13 Steel Substrate Nitriding on AlCrN, ZrN, TiSiN, and TiCrN Multilayer PVD Coatings Wear and Friction Behaviors at a Different Temperature Level

Moving components of industrial machines and tools are subjected to wear and friction. This reduces their useful life and efficiency in running conditions, particularly at high temperatures. One of the most popular solutions is to apply an appropriate surface coating to the tribocouple’s base materials. In this study, tribometer experiments were used to evaluate the tribological performance of cathodic arc physical vapor deposited (CAPVD) AlCrN, TiSiN, CrTiN, and ZrN coatings on the gas nitrided AISI H13 tool steel to explore the effects of nitriding the steel on wear and friction behavior of these coatings at ambient and elevated temperatures. The coatings characterization is split into three main parts: mechanical, morphological, and chemical characterization. Nanoindentation has been used for mechanical characterization, thin film X-ray diffraction (XRD), and an energy-dispersive X-ray spectrometer mounted on a scanning electron microscope for chemical characterization, optical profilometer, and atomic force microscopy (AFM) for morphological characterization. Significant improvements in the adhesion qualities of the coatings to the substrate were achieved as a result of nitration. Due to this circumstance, the coatings’ load-bearing capacity and high-temperature wear resistance ratings were enhanced. The wear results showed that the AISI H13 tool steel nitriding with AlCrN and ZrN layers decreased wear rates by two to three times at 700 °C.

“…Tungsten inert gas (TIG) welding torch and Plasma torch can be used as heat sources for surface treatment of engineering materials. Plasma is an ionized gas column that possesses high heat energy; plasma arc machining (PAM) is generally used for metal cutting [133]. In PAM, different gasses are used for different materials, but in maximum cases, nitrogen is used as assisting gas for plasma arc machining (PAM).…”

This article comprehensively reviews the causes of wear of hydraulic components used in hydro-static transmission systems and their remedies by thermal coating processes. The wear of critical components of the hydraulic pump and motors, hydraulic valves, etc., is mainly due to abrasion, erosion, and cavitation. The most commonly found modes of wear in hydraulic components are contamination and abrasion wear. Such wear arresting can be done by using the surface coating and texturing of materials over the wear zones of the damaged parts. This article discusses the causes of wear in hydraulic components and suggests various solutions to reduce such wear. Recent challenges associated with the proposed solution for wear arresting and future scopes are identified in this review. In the end, some novel techniques for the treatment of wear in hydraulic components, such as laser beam treatment, plasma, Tungsten inert gas arc, and Electric discharge coating, have been discussed, which is the potential future work for enhancing the useful life of hydraulic components. These surface treatment methodologies can be applied to alter the surfaces of crucial hydraulic components that experience considerable wear, as seen in hydraulic pumps, valves, and other elements such as hydraulic cylinders.
