Tribological behavior of eutectic Al-Si based composites in various solutions

Key Points

• The C3 sample showed the lowest coefficient of friction and wear across all environments, suggesting superior performance.
• In corrosion tests, C3 had the maximum average open circuit potential of 0.736V compared to lower values for others.
• The better wear resistance in C3 is linked to the oxide layer formation, which reduces material loss effectively.
• Friction and wear results across dry, aqueous, and alkaline conditions highlight the composite's varied behavior in different environments.
