“…The normal probability plot of the residuals for particle size and degree of sphericity shows that the residuals are falling near the straight line, reflecting that the errors are distributed normally, Figure 8a and Figure 9a. The residual plot for the particle size and degree of sphericity reveals that there is no absurd pattern since all the run residues lie on or between the levels of −4 and 4 as reported in the standard literature, Figures 8b, 9b [3, 31–33].…”

“…There are various discontinuous reinforcement materials used to synthesize the metal matrix composite such as silicon carbide, aluminium oxide, boron carbide, titanium diboride, etc. [3][4][5][6].

“…Fly ash cenosphere composites have a higher strength-to-weight ratio compared to the various discontinuous reinforcement at comparatively low cost [7]. Fly ash cenosphere is a by-product of thermal power plants having a density of 0.1 g/cm 3 to 0.8 g/ cm 3 . The main constituents in fly ash cenosphere are silicon dioxide (quartz), alumina, and potassium dioxide, which makes it suitable as reinforcement in aluminium matrix composites, making it the most prominent for fabricating low-cost aluminium matrix composites [8][9].…”

The current work examines the results of an experimental study for the liquid casting of an aluminum‐6061‐5 weight % fly ash cenosphere composite by employing stir casting. The studies were conducted using the response surface methodology (central composite design L16 experiments) with three process factors (stirring temperature, stirring speed, and stirring time) at three different levels. An attempt has been made to determine the impact of process variables on the degree of sphericity and particle size. The optimal processing conditions for the best degree of sphericity (0.765) and particle size (93.227 μm) are identified as A−1, B+1, and C+1, corresponding to a stirring temperature of 670 °C, a stirring speed of 600 min−1, and 15 min stirring time. Based on the analysis of variance analysis, the degree of sphericity and particle size evolution is significantly influenced by stirring time followed by temperature and speed. Additionally, a mathematical model for the evaluation of the degree of sphericity and particle size in the primary‐aluminium phase has been developed and it shows good consensus with the experiments.

The current study has examined the dry sliding wear behaviour of MoS 2 and SiC reinforced aluminium composites. An aluminium matrix reinforced with SiC and MoS 2 was used for this investigation. Silicon carbide (SiC) and molybdenum disulphide (MoS 2 ) particles are employed as reinforcements, and the matrix is made of the aluminium alloy series Al6061. Three weight steps were used to adjust the SiC and MoS 2 reinforcements in the Al6061 matrix from 3% to 5%. Dry sliding wear behaviour is examined using a pin-on-disc apparatus. Additionally, the test was further validated using a suitable set of parameters that confirmed Taguchi's findings. The Brinnell hardness test is used to determine the composite material's hardness. When the percentage of reinforcement reaches 3% SiC and 5% MoS 2 , wear is less compared to a combination of 5% SiC and 3% MoS 2 . By increasing the MoS 2 percentage of reinforcement, wear was consequently decreased. The microstructure of AL6061/SiC/MoS 2 composites is evident from the scanning electron microscopy images, where the silicon carbide (SiC) phase and the molybdenum disulfide (MoS 2 ) phase are evenly distributed throughout the matrix.

“…MoS 2 is not only Lubricants 2023, 11, 283 2 of 14 used as a coating in tribological contact but also specifically in material alloys to improve dry sliding properties. Ragupathy et al used MoS 2 in an aluminium alloy and were able to significantly reduce the dry sliding properties [5]. The use of MoS 2 as a nanoparticle is a new field of research in which individual flakes or layers of MoS 2 are used in tribological contact, similarly to the case with graphene [6,7].…”

Investigation of the Hardness Development of Molybdenum Coatings under Thermal and Tribological Loading

The increasing global demand for innovative and environmentally friendly lubricants can be met through the use of solid lubricants. By switching from conventional lubricants such as various oils or grease to solid lubricants, new scopes of application can also be opened up. The main requirements for solid lubricants are a reduction in the coefficient of friction (CoF) and an increase in wear resistance. Due to the favourable material properties, molybdenum (Mo) coatings fulfil the tribological requirements and are therefore promising solid lubricants which can be applied via physical vapour deposition (PVD). In this work, the impact of substrate temperature on the hot hardness of deposited Mo coatings was determined. The specimen with the highest hot hardness was then tribologically examined both at the micro and nano level. Through an analysis of the wear tracks by means of nanoindentation and scanning electron microscopy (SEM), it was possible to detect the influence of the tribological load separately from that of the thermal loads. The results showed that the tribological load influenced the Mo coating by significantly increasing its hardness. This was achieved due to the work hardening of the Mo layer leading to an increase in the wear resistance of the coating.
