Wear and Friction Behavior of Stir Cast Al-TiB2 Metal Matrix Composites with Various Lubricants

Blog Article

Al- TiB2 metal matrix composites are fabricated using stir cast method and its tribological characterization is done using three Holders different lubricants.Tribological studies are performed in a multi-tribotester using block-on-roller configuration under 25-75 N loads and 400-600 rpm rotational speeds.Four different weight percentages of TiB2 are considered in this study.Comparison between dry condition and lubricated conditions is gleaned to differentiate wear and friction characteristics and Anti-Aging SEM images are taken to fortify them.

Lubricated conditions yield large reduction in wear and friction compared to dry condition.
