“…Using the bottom pouring process, the melt was carefully transferred into the steel die via a heated conduit. A pressure of 150 MPa [31,32] was maintained during casting at each pressing, and the pressure remained at this level until the solidi cation process ended. The hydraulic press, employed to punch the steel die after the introduction of the molten matrix, was permitted to naturally cool to ambient room temperature.…”

This study aimed to fabricate hybrid metal matrix composites of AZ91D magnesium reinforced with varying various weight percentages of SiC and constant weight percentages of BN particles through the stir-squeeze casting method. The influence of the particle ratio on the microstructure and wear behaviour of the composites was studied. The dispersion patterns of particles within the matrix and the interactions between the alloy and the particles were thoroughly investigated using a variety of techniques, including optical microscopy, SEM, EPMA, and EDS.XRD analysis of the AZ91D/SiC/BN hybrid composite revealed a significant volume proportion of the strong Mg17Al12 phase. The synthesized magnesium hybrid composites (AZ91D/9%SiC/3%BN) experienced a volume loss reduction of up to 36.16% under a maximum load of 30 N and a maximum speed of 1 m/s when compared with the monolithic material AZ91D. The results of these analyses demonstrated that the resulting composites exhibited an even dispersion of particles, superior grain structure, and strong interfacial bonding between the AZ91 alloy and the reinforcing particles. The newly developed magnesium hybrid composites have better wear performance than monolithic AZ91D alloys. These findings highlight the enhanced wear resistance of the fabricated composites for antiwear applications.

“…Reinforced TiN (titanium nitride) and hBN (hexagonal boron nitride) particles on Mg composites and studied the corrosion behaviour at varying ageing temperature particles significantly improved the corrosion resistance of both composites and hybrid composites during the tribo-corrosion test [21]. The influence of NaCl in magnesium metal matrix composites reinforced with ZnO, MnO, and TiO2, these inclusive enhanced the corrosion behaviour of the composites [22].…”

“…The influence of NaCl in magnesium metal matrix composites reinforced with ZnO, MnO, and TiO2, these inclusive enhanced the corrosion behaviour of the composites [22]. The electrochemical studies revealed that Z91D/TiO2 nanocomposite showed minimal OCP drop (−0.7 to −1.0 V) and COF (0.10) at 2.5% NaCl concentration due to a thick oxide layer that shielded the surface from wear and Clduring the tribo-corrosion test [23]. To our author's knowledge and from the literature it is revealed that the works are concentrated-based conventional welding such as MIG, TIG welding process, and the corrosion behaviour of the weld joint only.…”

In this investigation, the corrosion study was conducted on fiber laser welded joints of AISI 410 and 316L stainless steel plates using hydrochloric acid, basic, and salt medium, behavior in three different pH. The effects of three different corrosive atmospheres were examined using the weight loss method. The test sample which was exposed to 1 N hydrochloric acid medium for 48 Hours resulted in 0.006 g of weight loss. The maximum amount of corrosion was found in the acidic medium whereas the least was observed in the salt medium. The effectiveness of three distinct derivatives of 1H-indole-2,3-dione, each replaced with hydroxyl groups in various positions, in inhibiting corrosion. Among the three derivatives examined, it was observed that those with ortho and para hydroxyl group substitutions exhibited superior inhibitory properties.

In recent decades, there has been a notable advancement in the field of bioactive, biodegradable, and biocompatible metallic materials, particularly for applications in general surgery. Among these materials, magnesium alloy-based composites have gained popularity due to their excellent biological properties and adequate strength. However, their resistance to wear is still an area that requires further investigation. Therefore, this study examines the wear properties of stir-ultrasonic-squeeze-casted magnesium (AZ91D) composites, incorporating distinct nanoparticles such as ZnO, MnO, and TiO2. The Evaluation-based Distance from Average Solution (EDAS) approach is used to determine the optimal parameters. Additionally, an Analysis of Variance (ANOVA) is conducted to identify the crucial factors influencing the responses. The effect of process factors on the wear rate and Coefficient of Friction (COF) is then investigated using response surface plots. The confirmation assessments reveal that the optimal parameter conditions for the tribo process comprise a 50.0018 N applied load, a 1.4998 m/s sliding velocity, and the AZ91D + 1% TiO2 (ATO) composite utilization. The ANOVA findings demonstrate that the applied load significantly contributes to 67.3% of the wear performance. Subsequently, after determining the optimal condition, it is observed that the ATO composite, when exposed to temperatures above 150 °C, exhibits an abrupt increase in wear rate and COF due to the degradation of grain strength and the dissolution of the β-phase within the composite.
