Effect of Temperature on Friction Behavior of Epoxy Resin Composite Coatings for Sliding Contact

Epoxy composite coatings are used to reduce friction in mechanical components. The epoxy composites at high temperatures cause serious frictional effects due poor surface characteristics. Hence, there is a need find substitute improve their behaviour high-temperature conditions. Adding fillers and lubrication key solutions tribological properties. In this research work, diglycidyl ether of bisphenol A (DGEBA) resin was coated on steel, silica powder (5% by weight) as filler. experiments were conducted under dry lubricated conditions with without coefficient (COF) examined different temperatures. results show that the COF increases an increase temperature. addition, minimum average observed case coating filler For case, up 94.4% decrease compared conditions, 48.33% 17.98% than condition perceived. Scanning Electron Microscopy (SEM) roughness analyses also examine specimen after experiment. worn rougher more thermal degradation matrix temperatures, which surface.
