Metallurgy Process

Aluminum matrix composites reinforced with carbon fibers or diamond particles have been fabricated by a powder metallurgy process and characterized for thermal management applications. Al/C composite is a nonreactive system (absence of chemical reaction between the metallic matrix and the ceramic reinforcement) due to the presence of an alumina layer on the surface of the aluminum powder particles. In order to achieve fully dense materials and to enhance the thermo-mechanical properties of the Al/C composite materials, a semi-liquid method has been carried out with the addition of a small amount of Al-Si alloys in the Al matrix. Thermal conductivity and coefficient of thermal expansion were enhanced as compared with Al/C composites without Al-Si alloys and the experimental values were close to the ones predicted by analytical models.

Metallurgy Process

Copper matrix composite reinforced with fly ash is prepared by powder metallurgy process. Three composites with 0%, 2.5% and 5% fly ash proportion are prepared. The specimens were compacted at 450MPa and Sintered at 950℃ for a period of 30 minutes in powder metallurgy technique. The prepared specimens were subjected to different corrosion environments (alkaline and acidic) and the corroded surface will be analysed using SEM/EDX.
