| Abstract | (Wear is a phenomenon in which surface materials damage or loss between two contact solids surfaces in sliding, rolling, or impact movement. In most cases, wear is caused by the interaction of surface asperities. To reduce the energy loss and equipment damage generated due to the mechanical parts friction in the operation, around the world is stepping up developing appropriate lubricants and lubrication technology. The antifriction ability of powder lubrication and the state of powder layer are strongly related to the service conditions. Therefore, the effects of sliding velocity and normal load under powder lubrication were studied using a pin on disc contact apparatus. In our work, some solid lubricants, ie. Molybdenum disulfide and serpentine powders were separately introduced into the frictional interface in the state of solid lubricants. The wear rate optimized content of these powders was obtained in the lubricant oil SAE90, mineral gear oil (Iraqi petroleum products), and it were examined that the loads and friction pairs move velocity’s changes had effect to tribological performance in friction course. This work focuses on studying urgency and favorable prospects of practical use of firm powder additives on the basis of serpentine, and molybdenum disulfide powders and their effect on tribological characteristics of lubricant oil (SAE90). Optimum lubricating effect concluded on the level of concentration of the serpentine and MoS2 additive powders in the range of (1.25 – 1.5) wt % and (2 – 3) wt% respectively, by the formation of protective boundary layer between the sliding tribosur faces that prevents wear. Tribological characteristics significantly improved i.e. the wear rate dropped about (3-3.5) times with serpentine powder and about (2-2.5) times with MoS2 powder compared with the case of using the lubricant oil without additives) Keywords— (Solid lubri cant powder, tribological characteristics, wear rate, lubricant oil. |
