常見例句Once tube wall is overheated, oxidation corrosion rate is not only accelerated, hut also the tube performance is rapidly deteriorated. 一旦管壁過熱不僅加速氧化腐蝕速率,且急劇惡化管材性能。Heat treatment improves the corrosion rate of the alloys, except T6 treated AZ91D alloy. 與鑄態(tài)合金腐蝕速度相比,黃正華西安理工大學(xué)碩士學(xué)位論文熱處理提高合金腐蝕速度(T6處理態(tài)AZ91D合金除外)。The increase of H_2SO_3 accelerated the anodic process and accelerated the corrosion rate of A_3 steel. 向溶液中加入H2SO3,會促進(jìn)A3鋼腐蝕反應(yīng)陽極過程的進(jìn)行,使A3鋼的腐蝕速率加快;With the temperature increased, corrosion rate became higher due to increase of film thickness and condensation rate. 當(dāng)濕氣溫度較高時,腐蝕速率隨液膜厚度、冷凝速率和液膜溫度的增加而增大。Relatively,the corrosion rate of Zn deposit was higher in Jiangjin than that in other places. 通過數(shù)據(jù)處理可知,鋅防護(hù)層在江津的腐蝕率最高,青島其次,海南萬寧次之,武漢腐蝕率最低。The contrast of galvanic current determined by ACM to corrosion rate of A3 steel showed that it was practicable to monitor corrosion of rain with ACM. ACM測量的電偶電流隨雨水pH值的變化與失重法測量的A3鋼的腐蝕速率隨雨水pH值變化的結(jié)果對比表明,利用ACM監(jiān)測降雨對A3鋼的腐蝕性是可行的。 返回 corrosion-rate
