| 520 | _aRecently, nanoparticles are used as additives to improve the tribological behavior of lubricating oil. This study is basically concerned with studying the tribological behavior of lubricated contents when introducing nano scale additive of carbon particles to lubricating oils. A test apparatus was developed to synthesis carbon nanomaterials by arc discharge between two pure graphite electrodes in liquid medium of deionized water or paraffin oil. Also a microcontroller circuit was devised and attached to apparatus in order to maintain the arc with continuous and safe operation. Carbon nanotubes (CNTs) was produced by arc discharge process from the anode material by using deionized water as discharge medium. It was found that the efficiency of the arc process range between - 15% and - 35%. The CNTs were added to commercial oil from the local market. It was found that addition of 0.01% of CNTs into mobil Oil (20W50) reduces the coefficient of friction by - 35%, and improves the wear scratch length and width with average - 18% and - 20% respectively at loads below normal load of 84 N | ||
