The current study deals with the tribological characterization of AZ31-B4C composites synthesized through ultrasonic vibration associated stir casting route. B4C particles with varying weight percentage (0.5–2.0 wt. %) are reinforced in magnesium alloy to produce the composites. Optical microscope (OM), scanning electron microscope (SEM) and energy dispersive x-ray analysis (EDX) are utilized to characterize AZ31 alloy and composites so fabricated. Characterization illustrates the presence of boron carbide (B4C) and its effect on the grain refinement of composites. Micro hardness of composites is measured through Vickers's micro hardness tester. AZ31-B4C composites exhibit better hardness compared to AZ31 magnesium alloy. Micro hardness of AZ31- 2B4C composite is increased by about 49% compared to AZ31 alloy. Dry sliding tribological behavior is investigated using a pin-on-disc tribo-tester. Wear behavior of AZ31 alloy and AZ31-B4C composites is investigated under applied load of 10–40N and sliding speed of 0.1 to 0.4 m/s. The composites show better wear and friction behavior. Wear resistance of AZ31-2B4C composite is improved around 30% compared to base alloy when tested at 0.2 m/s sliding speed and 40N load. SEM and EDX analysis of worn-out surfaces reveal the wear mechanisms based on different sliding parameters. The wear morphology of pin samples reveals the presence of abrasion, oxidation, adhesion and delamination mechanism either occurring individually or in mixed mode on the pin surface.

Recently, Thirugnanasambandham et al 30 studied the influence of load and sliding speed on dry sliding wear behavior of Mg-Al 2 O 3 nano composite. Dry sliding tests were carried out for fixed sliding distance at varying loads and speeds.…”

“…Figure 12d shows that low debris is observed, and 12% hybrid composite results in a smooth surface and improving wear resistance. Increased molybdenum trioxide and palm oil shell ash particles, according to Thirugnanasambandham et al [35], improve the Mg matrix wear characteristics. As the matrix level rises, the fracture surface will transform from brittle to ductile.…”

In India, urban solid waste generation has risen over the last decade. The aspect of waste generation is a large amount of waste materials among all solid waste types. While using ash particles eliminates waste, it also contributes desirable qualities. In this research work, the effects of Himalayan nettle leaf ash (HNLA) bean pod ash (BPA) with molybdenum trioxide (MoO3) on the ZWK611 (Mg-Zn6.0-Y1.2-Zr0.2) alloy is examined. The as-cast alloy exhibits an α-Mg matrix, and cubic γ-phases are formed in addition to MoO3 particles. In this work, an attempt was made to choose a ZWK611 alloy reinforced with HNLA and BPA by varying weight percentages (X = 4, 8, 12, and 15%) with a constant weight percentage of MoO3 (5%) fabricated using spark plasma sintering (SPS) technique. The mechanical and physical properties were tested for both as-cast alloy and magnesium hybrid composites. Surface morphology and XRD are analysed to identify material behaviour. The addition of 12%(HNLA-BPA)/5%(MoO3) hybrid composite exhibits high strength as compared to the as-cast alloy.

“…At this point, 50 nm alumina particle is added at 100 rpm and is mixed uniformly, which is also done in an inert atmosphere. After this step, the molten metal is cast, and then proper machining is done for the desired shape and dimension [21]. It was observed that the composite with 10% weight of alumina is showing better wear resistance.…”

Composite materials are being widely studied for the last few decades, and it has optimized the day to day applications in the engineering field. In this advancement, the use and development of metal matrices was a significant outcome that concentrated on the addition of many particulate materials in a metal matrix at nano and micro levels. Among these Magnesium, metal matrices are having a high potential, especially in transport, defense, and aircraft industries. Many research works are being carried out to use the capabilities of Magnesium and has provided excellent results. This paper is an overview of the development, processing, and improvement of properties in Magnesium alloys. Various manufacturing processes such as self-propagating high-temperature method, stir casting, laser cladding, and powder metallurgy has been used to develop the magnesium composites for increasing the properties by using various wt% of reinforcements added in the matrix. The improvement in mechanical properties such as tensile strength, yield strength, hardness and tribological properties such as wear rate is reviewed. The different properties and capabilities of Magnesium alloys such as AZ31, AZ91, and ZE41 is also discussed from the various research works.
