“…It was observed that the sliding distance is insignificant (3.3%) to tribological behavior. Also, it was observed by the author's previous report, the sliding distance is not more significant than the dry sliding behavior above 500 m [17]. Hence, a confirmation test is carried out to check the accuracy of the analysis after optimizing the process parameters.…”

“…The obtained average wear rate and CoF from the L 16 orthogonal array were taken as input for the grey relational analysis. Various steps involved in the grey relational analysis like normalization, grey relational co-efficient and grey relational grades are evaluated using equation number (2)-(4), respectively [17]. Also, the evaluated normalized value, grey relational coefficient, grey relation grade, and rank are shown in table 3.…”

“…Especially, in terms of good wear resistance and chemical stability in the corrosive environment. Hence in the previous articles [15][16][17], the author has developed a CaB 6 reinforced Mg composite and observed that the CaB 6 particles are capable of enhancing the mechanical and tribological behavior of the composite. To further enhance the mechanical behavior and wear resistance, the present article implements the heat treatment process (Age hardening) for AZ31 Magnesium-CaB 6 composites.…”

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.

<div class="section abstract"><div class="htmlview paragraph">Different weight percentages (0, 1 and 2 wt. %) of Calcium hexaboride (CaB<sub>6</sub>) is reinforced with pure magnesium and the composite is fabricated through powder metallurgy technique. The fabricated samples are used for the tribological evaluation. In this connection, the Taguchi optimization technique (L27 Orthogonal array) assisted Grey Relational analysis is used for predicting the significant factors to the tribological evaluation. The magnesium composite wear rate is evaluated by Archard’s mass loss method. Based on the obtained results, it is observed that the magnesium composite wear rate is increased by the effect of an increase in load. It was arising as a result of enhanced delamination wear mechanism which is confirmed by SEM observation on the worn-out pin surface.</div></div>
