【導讀】在不同的撞擊角度從15°到90°不等，四個不同的速度，35，和40米。/秒和飛灰顆粒四個不同的進給率2，4，6和8克/分鐘對侵蝕率進行評估。是不規(guī)則形狀，大小不等從50-250微米的飛灰顆粒。發(fā)現(xiàn)侵蝕率在30°的撞擊角度時。恒定速度為米/秒進行了研究。所有情況下，退火管的侵蝕速率總小于正火管。的撞擊角度和目標材料的伸長屬性的經(jīng)驗關系找到了。管元件一旦不能維持其結(jié)構(gòu)的完整性就出故障了。一旦發(fā)生這種情況，電廠將被關閉，并蒙受損失。瓚[1]表示，飛灰侵蝕幾乎占所有管故障的三分之一是受主要關注的。他們進行的實驗，并得出結(jié)論，韌性材料碰撞粒子造成嚴。子數(shù)不增加侵蝕率由于籃板顆粒提供的屏蔽效應以同樣的方式把顆粒數(shù)量傳到樣本。材料，并發(fā)現(xiàn)，材料具有較高的伸長率使侵蝕率降低。材料損失是由壓痕過程引起的。現(xiàn)侵蝕率與撞擊粒子累計重量相反。蝕所產(chǎn)生的隕坑擠壓，并證實侵蝕機理不僅僅是微切削機理。侵蝕率以樣品質(zhì)量損失率和飛灰使用率來計算。
