IMPROVEMENT OF TEMPERTURE RESISTANCE OF Al-Mg/Al2O3P COMPOSITE BY COATING WITH ANTIMONY TRIOXIDE FILM

Authors

Abstract
Aluminum matrix composites AMCS with 10 wt % Al2O3 particles with average size (3.86 µm) were fabricated by stir casting method, then the composite produced coated with Antimony Trioxide (Sb2O3) by hot dipping coating process. Thermal conductivity of composite materials with and without coating was estimated by applying Fourier equation to investigate its behavior under different temperature conditions. Results revealed that coating with antimony trioxide decreased the thermal conductivity (k) of composite material. The thermal conductivity of the master composite material was (207 W/mC) at (80 C) and (182 W/mC) of the coated composite material at same temperature.
