摘要
通过对样品A356.2铸造铝合金进行金相拍照分析其表面微观结构,在实验室条件下,采用经典的失重法对试验样品进行测量和计算,四组试验温度分别为25℃、30℃、35℃、40℃,在3.5%NaCl溶液完全浸没48h的条件下,失重数据结果表明该型号铝合金腐蚀程度随着温度改变存在一个临界温度。
The samples of A356.2 casting aluminum alloy by metallographic pictures of its surface microstructure, under laboratory conditions, using the classical weight-loss method of test samples were measured and calculated, four groups of test temperature with 25℃、30℃、35℃、40℃, in 3.5% NaCl solution was completely immersed for 48 h conditions. Weightlessness data results show that the model with the temperature change of aluminium alloy corrosion extent and a critical temperature
