“…In this paper, equal weights are taken for all the considered responses. The Grey Euclidean and Grey Taxicab distances are then calculated using equations (21) and (22) respectively as presented in table 8. Based on the calculated grey Euclidean and grey Taxicab distances, the relative assessment matrix is then obtained following the computation steps provided in step 8 of section 2.7.…”

“…The magnetron sputtering process is a very well-known synthesis process for the deposition of TiCN coating with refined grain structure and enhanced wear resistance. The flexibility of achieving low impurities, along with ease in control over the deposition parameters during film deposition, resulted in the formation of a good quality film [22]. From past research work of magnetron sputtered TiCN thin film, it has been found that the deposition parameters (e.g., composition and operating pressure of reactive gas, operating temperature, target to substrate distance, flow rate of reactive gas, target and substrate composition, and substrate bias voltage) play a vital role in achieving sound properties of the coating [21,22].…”

Mamaeva et al [23] investigated the effect of substrate bias (0, −70 V, and −100 V) over the structural, mechanical and tribological properties of TICN coating.…”

This experimental study focuses on the deposition of TiCN thin film coating onto a bare p-type silicon substrate using physical vapor deposition (PVD) processes, with varying process parameters. The study employed a design of experiment in accordance with the L 16 orthogonal Array, followed by the implementation of the combinative distance-based assessment (CODAS) method functionalized with grey numbers to enhance the performance of the PVD process for the very first time in the film of thin film deposition. The study also conducted various analyses to examine the coating’s properties, including morphological, structural, microstructural, electrochemical, and mechanical properties. According to the result, the morphology of the coating was wavy in nature, with a smooth microstructure and a few agglomerated particles. The structure of the film indicated that TiCN had a single-phase FCC structure, while the mechanical and electrochemical properties improved with higher N2 flow rates. Additionally, the analysis by CODAS method functionalized with grey numbers suggested that substrate to target distance = 50 mm, N2 flow rate = 25 sccm, and bias voltage = −120 V were the most suitable condition for obtaining the best quality of TiCN thin film coating.

“…The crack resistance of the coatings was determined by calculating the deformation relative to yielding (H/E) and resistance to plastic indentation (H 3 /E 2 ) ratios based on the nanoindentation values, the results of which are summarized in Table 4. Generally, the H/E and H 3 /E 2 ratios are proportional to plastic deformation resistance [47,48]. Large areas of the TD0-18% and TD50-3% samples were subject to film peeling, which can be attributed to lower H/E and H 3 /E 2 ratios and a thicker AlTiN layer.…”

The good mechanical properties of metal nitrides make them ideal surface coatings for cutting tools and mold components. Conventional TiN coatings have largely been replaced by AlTiN due to their superior mechanical properties and resistance to high temperatures. In this study, we investigated the application of bias voltage to the substrate to enhance ion bombardment during the synthesis of protective AlTiN coatings using high-power impulse magnetron sputtering (HiPIMS) with synchronous trigger-direct current (ST-DC) bias voltage. The ST-DC parameters included the duty cycle duration (3%, 6%, 12%, 18%) and turn-on time, which included synchronous (TD0) or a trigger delay of 50 μs (TD50). Scanning electron microscope images revealed that the highest deposition rate (22.1 nm/min) was achieved using TD50 with a duty cycle of 3%. The results obtained using an electron probe microanalyzer and X-ray diffractometer revealed the formation of an h-AlN structure when the Al/Ti ratio was between 0.71 and 0.74. Transmission electron microscopy and nanoindentation results revealed that transforming DC bias into synchronous bias to boost the bias output time (i.e., increasing the duty cycle) increased AlTiN grain refinement (from ~100 nm to ~55 nm) with a corresponding increase in hardness (from 22.7 GPa to 24.7 GPa) as well as an increase in residual stress within the AlTiN coating (from 0.16 GPa to −51 GPa). The excellent adhesion performance of the coatings provided further evidence indicating the importance of duty cycle and trigger delay when using pulsed-DC bias in HiPIMS.

“…In addition, the TiCrN coating showed the highest hardness and the MoS 2 showed the lowest. According to the report of Özkan [30], the high hardness of the TiCrN coating is mainly due to the high strength of the covalent bonds. Compared to the TM0 coating, the TM1-TM4 coatings showed higher hardness and elastic modulus.…”

Microstructures, Composition and Tribological Behavior of TiCrN/MoS2–TiCr Coatings Deposited by Magnetron Sputtering

To enhance the tribological performance of the conventional TiCrN coating, the MoS2–TiCr coatings are deposited onto the TiCrN layer by magnetron sputtering. In general, the MoS2 is implemented to enhance the friction reduction performance of the TiCrN coating, while the Ti and Cr are doped to increase the density of the structure and prevent MoS2 from oxidizing. The results reveal that with an increase in the content of Ti and Cr in the MoS2–TiCr top layer, the hardness and the coating–substrate adhesion force of the composite coating increase, respectively, due to the compact top layer. Further, the optimized Ti and Cr doping in the MoS2 top layer greatly enhances the tribological properties of the TiCrN/MoS2–TiCr composite coating with a friction coefficient as low as 0.06 and the wear rate is only 6% of the TiCrN coating. The main reason for the excellent tribological properties of the TiCrN/MoS2–TiCr composite coating is probably due to the recrystallization of the MoS2 in the process of wear.
