一种水轮机叶片改性环氧树脂涂层防腐蚀防磨蚀方法
摘要：
本发明公开了一种水轮机叶片改性环氧树脂防腐蚀防磨蚀方法，其包括：(1)在叶片表面进行喷砂粗化；(2)用丙酮和乙醇清洗粗化叶片表面并干燥；(3)按照硬质TiN陶瓷颗粒占20-45wt％、端羟基液体橡胶改性环氧树脂余量的配比，制成浆料并混合均匀；(4)将所述浆料均匀涂抹在叶片表面，90-130℃下干燥，得到熔覆于叶片表面的TiN掺杂的端羟基液体橡胶改性环氧树脂耐磨耐腐蚀涂层。经在泥沙河流中试用1个月，未发现明显的磨蚀和腐蚀痕迹。
摘要（英）：

A modified-epoxy-resin-coating anticorrosion anti-abrasion method for water turbine blades is disclosed. The method includes (1) subjecting a blade surface to sandblast coarsening, (2) cleaning the coarsened blade surface with acetone and ethanol and drying the blade surface, (3) preparing slurry according to a ratio that the slurry includes 20-45 wt% of hard TiN ceramic particles, with the balance being hydroxy-terminated liquid rubber modified epoxy resin, and fully mixing the slurry, and (4) evenly coating the blade surface with the slurry, and drying the blade surface coated with the slurry at 90-130 DEG C to obtain a TiN-doped hydroxy-terminated liquid rubber modified epoxy resin anticorrosion anti-abrasion coating covering the blade surface. Through 1 month of application in a sandy river, the blade surface does not have obvious corrosion and abrasion traces.
