Abstract

Polymer - based components are exposed to many damage influences during their lifetime. One of these influences erosion, which is a crucial problem in many industrial applications such as pipes, boats, sewage…etc. Due to impingements of solid particles being suspended in the fluids flowing at high velocity. This work reports an investigation of erosion wear characteristics and their resistance to erosion wear after coated by using (spin coating) with rice husk ash – mixed (epoxy resin). Composites specimens have been prepared by (Hand lay-up) molding method. The composite specimens are composed of epoxy resin as the matrix, and 6% vf of glass fiber as reinforcing material and filler powders from natural wastes and industrial processed powders at 3% and 6% vf. The natural wastes are rice husk ash (RHA), carrot waste and sawdust (wood powder) while industrial processed powders are Na2CO3, CaCO3 and K2CO3. Solid particles erosion wear tests and coating after erosion are also carried out. The coating specimens with RHA-mixed epoxy resin at an optimized size of the particles 1.4-4.2 µm improvement erosion wear resistance. The optical microscope results of the coated specimens show those coatings are resistant to erosion parameters.
