摘要
水工泄水建筑物表面涂复一层具有优异抗冲耐磨性能的聚氨酯(聚脲)高分子弹性体材料,抵抗过流时高速水流(有时含推移质)冲磨对建筑物的破坏,起到"以柔克刚"的功效,为减缓水工建筑物高速水流冲磨、气蚀破坏提出了一条新的解决途径。
Hydraulic outlet structures coated with a layer of polyurethane elastic erosion - abrasion resisting materials could prevent erosion damage of high velocity flow （ sometimes containing bed load） during discharging water. This kind of materials provides an effective solution to reducing erosion and cavitation damages of high velocity flow to hydraulic structures.
