Abstract:Al/Al2O3 and Al-5Si/Al2O3 composites were produced by spraying-oxidation and deposition process. The alumina was formed directly through the oxidation reaction of the molten aluminum during spraying atomization and was dispersed in the Al matrix after deposition and solidification. The structure of the composites was examined and the mechanical properties were determined. Also the effects of process parameters were investigated.
Key words: Al matrix composites spraying-oxidation and deposition structure and property
