In the present research a detailed effect of carbon-ions implantation in aluminum alloys (Al-Cu 2118 series) specimens at the room temperature by using a mathertype plasma focus device, operated with methane (a new process of plasma carburizing). Same treatment condition which has been reported in this study, fired at 15 kV giving a peak discharge current of about 150 kA over multiple focus shots. The results obtained indicates that the variation in focus shots has a significant impact on the surface hardness number of the Al-Cu 2118 series. The surface hardness number of the specimen increases continuously by increasing the ion content to 15 focus shots during the plasma carburizing process and reaches a maximum surface hardness number of 160 Kg.m-2, which is almost six times compared to the surface hardness number of Al-Cu 2118 series which is untreated. Enhanced surface hardness can be associated with the formation of Al4C3 and amorphous carbon phases. Based on this investigation, a plasma carburizing device was found to be an efficient device to obtain a harder aluminum alloy surface in a room temperature
