  1. Test method for erosion testing of antifouling paints using high velocity water

    用高速水對防污漆腐蝕檢驗的試驗方法
  2. The surface material is liable to erosion wear with high - velocity sediment - laden flow, hi this paper, sand wear mechanisms are discussed and some effects of significant flow factors on material wear are analyzed ; the possibility of preventing erosion wear with aeration is proposed ; based on test data, the formula for calculating the concrete material wall surface wear rate is derived. it is indicated that the wear rate is related to the air concentration, the strength of material, the flow velocity and the sediment content. it is shown that wear rate can be reduced with the help of flow aeration

    分析了空蝕與磨蝕的不同物理特徵;探討了沙粒磨蝕機理,提出了影響磨蝕vi河海大學博士學位論文一的因素;研究了摻氣抗磨的可能性:建立了混凝土材料壁面磨蝕率的計算公式;說明含沙水流對固壁材料的磨蝕率隨摻氣濃度、材料強度的增大而減小,隨水流流速、含沙量的提高而增大;利用摻氣可有效地降低過流表面的泥沙磨蝕率。
