The disposal of chicken eggshell (ES), a byproduct of aviculture, is a major environmental issue. Chicken eggshell can be utilized to create new low-cost, low-density consumer goods materials. In order to alleviate environmental difficulties, the proper usage of ES as a bio-waste should be actively pursued.
Composites emerged as the most promising materials in recent years. Nowadays, hybrid aluminium matrix composites were developed by utilizing of low-cost reinforcements with less density and high strength. Composite materials which were developed by use of agricultural waste as a reinforcement can be utilized in various applications/industries such as aeronautical, manufacturing, automobile etc.
The objective of present work is to find out the tribological characteristics of AA2024/SiC/carbonized eggshell hybrid green aluminium metal matrix composites (AMMCs). The wear rate (WR) and coefficient of friction (CF) were investigated at different combinations of load, reinforcement, sliding speed, and sliding distance.
A Taguchi-based L16 orthogonal array methodology was used to set up the combination of parameters. The mathematical models have been developed, and solved using non-dominating sorting genetic algorithm-II (NSGA-II). The solutions were predicted using NSGA-II were ranked using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The confirmation experiments were performed at three suggested settings (rank 1 to rank 3). In one of the patents (CN113957284B) the development method for hybrid composites is discussed.
The results revealed that hardness of AA2024 hybrid green composite was observed to be enhanced as compared to base aluminium alloy. Wear resistance of the AA2024/SiC/carbonized eggshell composite was also improved. The patents on Al composite (US 3649227) revealed that after the addition of reinforcement, the mechanical characteristics such as tensile strength was improved.
Wear resistance is improved on AA2024/SiC/carbonized eggshell composite. With an increase in reinforcement percentage and speed, the WR decreased from 29.16×10-5 g/min to 26×10-5 g/min. The CF increases from 0.4 to 0.46 with the increase in reinforcement percentage, from 3% to 12%.
