“…The mechanical and tribological behavior of aluminum-graphite (Al-Gr) composites is investigated in order to determine the optimum composition of reinforcement. 32 Kaviyarasan et al 37 followed the hardness and wear resistance property on the magnesium reinforced with 0.5%, 1%, 1.5%, and 2% wt.% of SiC manufactured via powder metallurgy technique. As a result, the average values for all the hardness test of pure Mg, 99.5% Mg 0.5% SiC, 99% Mg-1% SiC, 98.5% Mg-1.5% SiC, and 98% Mg-2% SiC was obtained as 13, 16, 27, 35, and 65 HV, respectively.…”

The objective of this research is to experimentally investigate the metallurgical, mechanical, and tribological behavior of [Formula: see text], SiC, and [Formula: see text] reinforced AZ31 magnesium metal matrix composite (MMC) fabricated via powder metallurgy process. Accordingly, the mixing of the powders was carried out through ball milling operation at various times with constant speeds. The compaction of the milled powder was carried out on hydraulic press at various compaction pressures. The improvement of the wear resistance performance at 10 and 5 vol.% SiC were revealed around 12.9% and 25.8%. The fracture mechanisms of the optimal specimen resulting from the compression test were studied under SEM observation and it revealed that both ductile and brittle fractures occurred. The results from the confirmation test revealed an improvement of 2.04 g/cm3, 13%, 110.35 MPa, and 1293.399 MPa for actual density, porosity, ultimate strength, and hardness, respectively. The uniform nature of particle distribution was observed in SEM micrograph under investigation of the microstructure of the sample. The average particle size of the sample was also obtained around 809.14 nm. The proposed material is expected to be useful for various automotive and aerospace applications precisely for pistons and wings of airplane in aerospace.

“…However, its utilization has been limited in several industrial applications due to poor ductility, thermal stability, creep, wear and corrosion resistance, etc [1,2]. Hence to improve the wear resistance of Mg, several metals, ceramics, and solid lubricants were added to the matrix through different processing techniques [3][4][5][6][7]. Amongst, the introduction of soluble elements (alloy) could induce grain refinement and high hardness due to the formation of new precipitates [2], which results in a low wear rate.…”

The usage of AZ31 magnesium alloy has been limited in tribology applications, due to low hardness and poor wear resistance. In this connection, the age-hardening process is a promising heat treatment process for enhancing mechanical strength and wear resistance. Hence, the present work aims to analyze the effect of the age-hardening process on the microstructure, mechanical and wear behavior of AZ31 Magnesium-Calcium hexaboride composites (Mg composite). Here, dry sliding wear behavior was analyzed with different loads (10, 20, and 30 N) and sliding velocity (0.4, 0.6, and 0.8 m. s−1) for a constant sliding distance of 2000m. Age hardened composites exhibited a higher hardness and compressive strength which was due to the increased volume of the secondary precipitates (Mg17Al12 and Al8Mn5). The morphology study revealed that there is an exhibition of shear bands and brittle fracture for Age hardened composites. The remarkable wear rate reduction was achieved for age hardening processed composites due to the increased load-bearing capacity induced by the presence of a high volume of secondary precipitates. Delamination wear is the dominant wear mechanism for the composites and the delaminated craters increases with increasing the load condition. Further, the elemental mapping on the collected wear debris was also used to confirm the wear mechanism.
