| Abstract | ||||
| In lubricating oils, oil additives are among very important parameters because they significantly improve the performance of motor oils and other types of lubricants. In this paper, spherical calcium carbonate and graphite particles were added to two types of lubricating oils (Paraffin and PAO oils). A tribometer was used to examine the oil's frictional properties using a stainless-steel pin on disc. Based on the experimental results calcium carbonate showed good dispersity and uniform particle distribution. When the CaCO3 addition is dispersed to PAO and paraffin oil, it performs well as a solid lubricant in reducing wear and friction on the steel specimens. The wear values were greatly enhanced when graphite particles were added to lubricating oils as a solid addition. Research results showed that the best concentration of the additives is 20 wt. %. As a result, the suggested coating approach lowers the steel specimens wear values and friction coefficient because the precipitated anti-wear serves as a barrier to lessen metallic contact. | ||||
