Experimental investigation on electrical properties and wear rate of aluminum matrix nanocomposite (AMNC)‎ of AA7100 Al2O3

الملخص EN

In this study metal matrix composite (AMMS) was successfully manufactured using stir casting route.

The influence of content on microstructure, electrical properties and wear resistance were investigated .

The microstructure of composite revealed that homogeneity of particles in the matrix and also the reinforcement of grains compared to matrix grains.

The homogeneity and reinforcement can be attributed to enhance the electrical and wear properties and this perhaps could due to efficiency of stirring process during the casting.

The content shifted the conductivity and permittivity from reducing in matrix to increasing in the composite when the frequency increased.

The wear resistance was improved due to addition of compared to matrix
