Effect of Quenching Medium on Sliding Tribology of Self-Lubricating Al-Cu Metal Matrix Composites

The cooling rate during fabrication affects the microstructural features and interface strength in metal matrix composites (MMCs). Thus, the present investigation is focused on characterizing the effect of quenching medium on wear and friction response of self-lubricating Al-Cu dual matrix composite...
