Erosion wear will not only cause economic losses, but also have a huge security risk. Fabrication of protective organic coatings on the substrate surface is an efficient and economical method to protect work piece. Epoxy resin displays excellent performance and is a promising erosion-wear resistance material to be applied in liquid-solid two-phase flow area, but it is hard to meet the rigorous demand during practical applications. Therefore, epoxy resin needs to be modified to further improve its erosion-wear resistance performance. This article systematically summarizes the modification methods for improving erosion-wear deterrence ability of epoxy resin, including organic molecular and filler modification. The erosion behavior of organic modified epoxy resin composites is discussed, the effects of different filler properties (filler size, content and type) on strengthening the erosion properties of epoxy resin composites under different working conditions (impact velocity, impact angle) are investigated. Based on the summary and analysis of the current antierosion technology, the existing problems and future research development trend of erosion-wear resistance epoxy materials are pointed out.
