一、前言对于均匀腐蚀,只要材料与环境确定,即可用腐蚀速率评价材料的耐蚀性。而局部腐蚀则不然,即使确定了材料和环境,但由于局部腐蚀具有可能发生或可能不发生这一概率性质,对于即使发生了局部腐蚀的情况,由于这种发生次数和程度具有随机性质(表现出腐蚀实验数据偏差大),因而用以往的方法是难以作出正确评价的。为了正确评价局部腐蚀,必须引入概率论。
First, the preface For uniform corrosion, as long as the material and the environment to determine, you can use the corrosion rate evaluation of the corrosion resistance of the material. However, even if local corrosion is determined, even if the material and the environment are determined, since the local corrosion may or may not occur with this probability property, even if local corrosion occurs, since the number and degree of such occurrence have a random nature Out of corrosion experimental data deviation), so with the previous method is difficult to make a correct assessment. In order to correctly evaluate the local corrosion, probability theory must be introduced.
