Tribological behavior and microstructural characteristics of stir-cast Al7075/SiC and Al7075/TiB₂ composites

Key Points

• Al7075 composites demonstrated enhanced tribological behavior compared to pure aluminum, with significant reductions in wear rate.
• The study reported a 30% decrease in wear rate for Al7075/SiC composites compared to Al7075 alone.
• Analysis employed a combination of wear tests and microstructural characterization techniques to evaluate performance.
• Findings suggest improved durability and performance of Al7075 composites, but further investigations into longevity are needed.
