There are several types of fan corrosion protection
2022/06/07
The stainless steel characteristics of the fan are reflected in the passivation protective film on its surface. The following is an analysis of the anti-corrosion mechanism of stainless steel fans. Generally, the corrosion types of stainless steel are divided into two categories: uniform corrosion and localized corrosion. Localized corrosion refers to a form of corrosion in which the matrix of steel is rapidly corroded at specific locations under the action of corrosive media. This kind of corrosion poses a great threat to equipment, so stainless steel is correctly selected according to the medium conditions. The main types of localized corrosion are: intergranular corrosion, pitting corrosion, stress corrosion, rust and so on.
Uniform corrosion means that all the exposed metal surfaces in the corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded. This kind of corrosion can also measure the speed of its progress, and can also predict the degree of corrosion in the future, set the coefficient, and set the service life of the material, so it is among the many types of corrosion. Not dangerous corrosion, usually uniform corrosion The degree of corrosion is determined by weight , to measure the thickness reduction.
