微生物腐蚀是一种特殊类型的腐蚀,它是由于微生物的直接或间接地参加了腐蚀过程所起的金属毁坏作用。微生物腐蚀一般不单独存在,往往总是和电化学腐蚀同时发生的,两者很难截然分开。引起腐蚀的微生物一般为细菌及真菌,但也有藻类及原生动物等,在大多数场合下都可看作是各种细菌共同作用而造成危害的。微生物影响腐蚀主要是通过使电极电位和浓差电池发生变化而间接参与腐蚀作用这条途径,其方式大体分以下几类: Microbial corrosion is a special type of corrosion that is caused by the destruction of metals by the direct or indirect participation of microorganisms in the corrosion process. Microbial corrosion generally does not exist alone, often and electrochemical corrosion occurs at the same time, the two are difficult to completely separate. Corrosive microorganisms are generally bacteria and fungi, but also algae and protozoa, etc., in most cases can be seen as a combination of various bacteria and cause harm. Micro-organisms affect the corrosion mainly by making the electrode potential and concentration of the battery changes indirectly involved in the corrosion of this approach, the general approach is divided into the following categories:
