Abstract
In order to produce an optimal performance solid lubricant used in the refractory slates, various compositions of starch, graphite and water were evaluated by testing their viscosity, coefficient of friction and wear performance. At 15% starch content, the degree of viscosity increment rose in proportional to graphite content and the lowest coefficient of friction was observed when the graphite content was at 30 wt%. Our results demonstrate that, as the water content decrease, the ratio of solid content increases, which compromises the surface coating resulting in increase of coefficient of friction. The best wear test result was obtained when the starch content was at 15 wt% with graphite content at either 25 wt% or 30 wt%.
