| Popis: | This research deals with the improvement of hardness property on the composite material made from aluminum matrix reinforced with carbon nanotubes (Al-CNTs). There were two experiments conducted to enhance hardness property; forging and friction surfacing process. An axial mechanical force forged the Al-CNTs composite up to 40% of height of a cylindrical aluminum. A thermo-mechanical force was also applied in producing Al-CNTs coating by the friction surfacing process using Al-CNTs composite rod. Then, the hardness property obtained from these two processes was investigated. Results of the experiments showed that the hardness of Al-CNTs after the forging process improved 40–50% due to high amount of dislocation during forging which avoids deformation. This was indicating that 1 wt% CNTs does not decrease the hardenability of aluminum alloys. Meanwhile, the hardness Al-CNTs coating was not altered too much by the process of friction surfacing. This is becaused that the homogenous dispersion of the CNTs have occurred during the stir casting process. |
