Wear studies of hybrid AMCs reinforced with naturally occurring sillimanite and rutile ceramic particles for brake-rotor applications
Source abstract
Abstract
Abstract Light weight hybrid aluminium matrix composites (AMCs) were developed for brake rotor applications and their wear behaviour was compared with commercial grade material under dry-sliding wear conditions. LM27 Al-alloy was reinforced with sillimanite/rutile particles (size: 1–32 μm; loading: 0–15 wt%.). Uniform distribution of reinforcement was achieved till 15 wt% level. High nano-hardness and high thermal conductivity at particle-matrix interface indicated good interfacial-bonding. Hybrid AMCs containing 15 wt% reinforcement showed 52% decrease in wear rate over base alloy and was comparable to commercial grade material used in industries. Hybrid AMCs displayed superior thermal conductivity over commercial material. Each reinforcement played a diverse but significant role. Sillimanite improved interfacial-bonding between matrix-reinforcement whereas rutile provided increased lubricity/grain refinement of the composites.
