Abstract

On the basis of arc metal deposition process the technology for carbon nanotubes (CNT) addition to metal was developed. It uses extruded metal rods with CNT’s as additional material. For this study the developed technology was used for modification of metal Al-5Mg alloy. Comparison of macro- and microstructure for metal obtained with developed technology with CNT’s and without it shows no strong difference for modified and not modified metal. Nevertheless CNT’s were observed in modified metal with use of SEM and analysis of microhardness showed that addition of CNT increases microhardness in upper layers of deposited metal.

Keywords: Carbon nanotubes, metal matrix composites, Al-5Mg alloy, modification, extrution
