摘要:

沖蝕磨損不僅會造成經濟損失，而且存在巨大的安全隱患。一種高效、經濟的保護方法是在工件表面涂覆有機防護材料。環氧樹脂具有優異的性能，作為抗沖蝕磨損材料的應用潛力很大，但是應用的高要求和苛刻的服役環境迫切需要對環氧樹脂進行改性來提高其抗沖蝕性能。系統總結了利用有機化合物改性環氧樹脂和填料改性環氧樹脂復合材料抗流體沖蝕磨損的研究進展；討論了有機物改性環氧樹脂復合材料的沖蝕行為，重點分析了不同特性的填料（填料尺寸、含量以及種類）增強環氧樹脂復合材料在不同的沖蝕工況條件（沖擊速度、沖擊角度）下所表現的沖蝕特性；通過對目前抗沖蝕機理的總結與分析，指出環氧樹脂抗沖蝕研究現存的問題并展望其未來發展趨勢。

Abstract:

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 anti�瞖rosion technology, the existing problems and future research development trend of erosion-wear resistance epoxy materials are pointed out.
