如果加速腐蚀试验的结果与自然腐蚀条件没有什么关系,也就是不能够预告用于基体金属的保护涂层的使用寿命时,加速腐蚀试验的结果一般没有什么大的价值。只有当存在一个关系系数时,其互相关系才成为可能(也可称为加速系数、关系值或加速值)。这种关系系数表示出由加速腐蚀的结果所得到的加速作用的数值,也就是说按照加速试验的一天来估计环境曝露的天数。本文由于缺乏同时处理加速试验与野外试验的结果,特别是他们的相互比较,是目前
If the results of the accelerated corrosion test are not related to the natural corrosion conditions, that is, they fail to predict the useful life of the protective coating for the base metal, the results of the accelerated corrosion test are generally of little value. It is only when there is a relationship coefficient that it is possible (also called acceleration coefficient, relational value or acceleration value). This relationship coefficient shows the value of the accelerating effect as a result of accelerated corrosion, that is, the number of days of environmental exposure is estimated on the basis of one day of accelerated testing. In this paper, due to the lack of simultaneous processing of accelerated test and field test results, especially their mutual comparison is the current
