Synthesis and Experimental Investigations of Tribological and Corrosion Performance of AZ61 Magnesium Alloy Hybrid Composites

Abstract

Magnesium alloy is the light weight material compared to aluminium alloy, and it possesses high strength; these alloys are used to manufacturing of vehicle parts. Magnesium alloy has extreme mechanical and thermal properties, and it is applied to aerospace applications. This study planned to improve the tribological and corrosion resistance of AZ61 magnesium alloy with reinforcement of boron carbide (B4C) and zirconium dioxide (ZrO2). Magnesium alloy hybrid composites are fabricated through stir casting process. Tribological and corrosion performance are analyzed through Taguchi L27 Orthogonal Array. In the tribological analysis, four parameters are involved such as % of reinforcement (4%, 8%, and 12%), disc speed (1 m/s, 2 m/s, and 3 m/s), normal load (30 N, 40 N, and 50 N), and sliding distance (1300 m, 1500 m, and 1700 m). Similarly, in salt spry corrosion analysis, four parameters are influenced used such as % of reinforcement (4%, 8%, and 12%), pH (7, 8, and 9), temperature (30°C, 35°C, and 40°C), and hanging time (30 hrs, 40 hrs, and 50 hrs). From this analysis, percentage of reinforcement is highly influenced in wear test, and in corrosion test, temperature is extremely influenced.

Physical and mechanical behavior of aluminum-magnesium alloy matrix hybrid composite fabricated through friction stir consolidation process

“…Application areas of magnesium metal matrix composites are piston, brake components, and steering shafts are some of Magnesium matrix composite. 6 In fabrication of magnesium matrix composite, processes such as; stir casting, powder metallurgy, friction stir processing, and squeeze infiltration technique have been implemented and results showed that the addition of MoS 2 and TiC improves the wear property of the matrix and good wettability property were achieved. 7 Magnesium matrix composite is alternatively preferable than aluminum matrix composite due to it has less density and high strength to weight ratio in addition to its wettability property.…”

“…The contribution of ZrO 2 in the magnesium alloy of AZ61 metal matrix enhances the wear resisting property of a composite. 6 Likewise, researchers studied the effects of ZrO 2 in AZ31 magnesium alloy and results depicts that there was an improvement in yield strength of a base material from 137 to 217 MPa of ZrO 2 reinforced magnesium alloy AZ31. 13 This shows that, the influence of ZrO 2 in magnesium alloy matrix is not only wear property enhancement but also yield strength.…”

Recycle of bio‐waste banana and sisal fiber filled harmlessness epoxy hybrid composite for automotive roof application

“…In addition, the waste of non‐biodegradable fibers is discarded into landfilling, resulting in giant environmental pollution (De Paiva et al., 2019). These natural fibers are chosen as alternatives and they contain low amounts of CO 2 , enhanced flexural strength, less weight, high tensile strength, low greenhouse emission, good thermal insulation, and successful acoustic effect (Aslan et al., 2018; Kannan et al., 2022). The various natural fibers are ramie, jute, cotton, banana, sisal, kenaf, coir, pineapple, and Bagasse, utilized as reinforcement for epoxy composites and attain specific properties like good tensile strength, impact toughness, good tribological characteristics, enhanced thermal insulation properties and less gas emission (Nguyen et al., 2019; Sumesh et al., 2021).…”

Recycling of waste aluminum/magnesium metal scrap into useful Al‐ZrO2 alloy composite for eco‐friendly structural applications

“…The waste recycled metal scrap reinforced aluminum alloy composite quality was experimentally evaluated by ASTM test standards (Overcash et al., 2017; Ramesh Kannan et al., 2022). Moreover, the developed composite characteristics like weight, mechanical strength, wear properties, and other properties were higher than the value of conventional cast alloy (Amaechi et al., 2020; Kahveci & Unal, 2000).…”
