含氯融雪剂腐蚀行为灰铸铁浸泡Chlorine Salt Snowmelt Agent The Corrosion Behavior Gray Cast Iron Soak

摘要:

利用金属腐蚀全浸泡试验方法测定了工业盐和环保型融雪剂对车用灰铸铁的腐蚀性,研究了腐蚀时间、融雪剂浓度对灰铸铁腐蚀速率的影响。结果表明:灰铸铁在环保型融雪剂溶液中的腐蚀速率低于其在工业盐溶液中的腐蚀速率;随着腐蚀时间增加,灰铸铁的腐蚀速率呈先增加后减小的趋势,48 h达到最大值;灰铸铁在工业盐溶液中的腐蚀速率随着溶液浓度的增加,先减小后增大;当浓度为2%时,腐蚀速率出现最小值。

The corrosion behavior of grey cast iron, which are used to make auto parts, in the industrial salt solution and environment-friendly snowmelt agent solution respectively, are studied by metal corrosion full immersion test method. The relationships of the corrosion rate of gray cast iron and the corrosion time as well as the snowmelt agent concentration are discussed. The results showed that: the corrosion rate of gray cast iron in the environment-friendly snowmelt agent solution is lower than that in the industry salt solution. With the increase of corrosion time, the corrosion rate of gray cast iron first increases then decreases, the maximum value appeared in 48 h. The corrosion rate of gray cast iron in industrial salt solution increases with the solution concentration, and first decreases then increases. When the concentration is 2%, the corrosion rate appears minimum value.
