“…The use of MMCs in diverse industries has increased significantly to meet the high demand in producing necessary and complex components for marine, aircraft, and automotive applications. Govindarajan et al [6] emphasized on the importance of MMCs in automobile industries since they play a critical role in offering a lightweight material exhibiting both high stiffness and sturdiness. Santhosh et al [7] reported that MMCs containing magnesium is potentially going to become one of the widely-used materials due to possessing higher energy efficiency as well as recyclability.…”

This study aimed to investigate the tribological and microstructural characteristics of LM26 composites reinforced with silicon carbide to evaluate their suitability for high-temperature applications. For the sample fabrication, the modified stir-casting method was optimized using a Taguchi L16 orthogonal array. The wear rate and friction behavior were evaluated using the Taguchi's S/N ratio analysis. When SiC was incorporated into the composite, the wear resistance increased by up to 15 wt. %. The wear resistance of the LM26/SiC composite was improved compared to that of the pure LM26 aluminum alloy. The results of this study provide useful information to improve the wettability of metal matrix composites made from commercial-grade LM26 aluminum alloy by adjusting the SiC weight percentage. This type of composite has the potential as a replacement material for traditional applications such as heat sinks, heat exchanger fins, and electronic packaging.

“…These flakes with no plastic deformation at the edge and some fatigue cracks are found inside the flakes, indicating that the wear is a typical sign of fatigue spalling. Therefore, the wear mechanism of sample a is mainly adhesive wear and fatigue wear [53,54]. As shown in Figure 19(a3,b3), most of the cracks in the substrate extended very seriously and gathered at the spalling and flakes.…”

As the main mechanical transmission parts, the gears are usually exposed to wear, corrosion, and fatigue; their failure in a poor working environment may cause a huge economic loss and waste of resources. Laser cladding (LC) has been proven to quickly repair parts at good metallurgical bonding performance and has flexible scanning strategies and a wide material selection. Therefore, LC technology can be considered an ideal approach to repairing damaged gear. However, the repair of damaged teeth by LC has not been systematically reported. In this paper, a series of progressive works have been carried out to systematically investigate the repair process of broken gears by LC. Firstly, process parameters, overlapping ratio, and Z-increment for Ni60 powder on 20CrMnTi were optimized. Secondly, the effects of deposition strategies on morphologies of single-layer and multi-layer multi-tracks were carefully analyzed. Then, the gear repair was successfully realized based on obtained optimized parameters. Finally, the phase composition, microstructure, hardness, and wear properties of the repaired gear tooth were analyzed by XRD, SEM, microhardness tester, and friction and wear tester. The results show that the remanufactured tooth can recover its appearance before breakage. The repaired zone is mainly composed of γ-Ni, Cr7C3, Cr23C6, and CrB phases. The micro-hardness and wear volume loss of the repaired zone is 60.63 ± 1.23HRC and 1674.983 μm2, which are consistent with those of the other teeth. This study is expected to expand the application of LC technology and provide guidance to engineers in the repair of damaged parts.

“…The hardness is improved, and the coefficient of friction (COF) and wear rate are minimized when the tungsten carbide is added to the titanium alloy matrix [8,9]. Adding nano-sized particles as an adjuvant decreases agglomeration during material preparation [10]. Hence, in this research, nano-sized tungsten carbide is used as an additive element for improving the wear resistance of Al 4043 alloy.…”

Al 4043 alloy is extensively used as a filler material for welding aluminum alloys, especially when welding alloys from the Al 6000 series. It is utilized in aerospace and automotive structural components. For longer life in automotive applications, the wear resistance of Al 4043 alloy must be improved. According to research, tungsten carbide has good wear resistance. In this research, Al 4043 alloy is reinforced with varying percentages (1, 3, and 5%) of nano-sized tungsten carbide to increase wear resistance. Taguchi L27 orthogonal array is employed for the wear analysis. The Taguchi signal-to-noise ratio is used to determine the optimal parameters for minimizing wear and coefficient of friction. The regression model and artificial neural network are developed to predict the experimental results. The outcomes of the regression model and artificial neural network are compared to the experimental results to demonstrate both models’ efficacy. A confirmation test was carried out for the optimal process parameter. The result shows that the minimized specific wear rate of 0.12 mm3/Nm, coefficient of friction of 0.01, and frictional force of 1.02 N are achieved at the optimal combination.
