Why can corrosion resistance be evaluated for uniform corrosion, but not for localized corrosion?
Because uniform corrosion can have its corrosion rate determined by weighing. In engineering, the thickness method is commonly used to express its velocity; therefore, the corrosion rate scale can be employed to assess the corrosion resistance of metals. Local corrosion occurs in specific areas or unknown locations, with the corrosion concentrated in those areas; as a result, it is not possible to measure the degree of corrosion using the thickness method, and therefore corrosion resistance cannot be assessed.

Local corrosion occurs in specific areas or unknown locations, with the corrosion concentrated in those areas; as a result, it is not possible to measure the degree of corrosion using the thickness method, and therefore corrosion resistance cannot be assessed.
Since there is no specific criterion for measuring localized corrosion, there are many uncertainties, as well as potential microscopic, internal, and uneven damages.

Uniform corrosion allows for the determination of the corrosion rate, which is generally expressed in terms of thickness loss. Therefore, corrosion resistance can be determined based on the corrosion rate. Local corrosion occurs in localized or unknown areas of the metal, with severe concentration of corrosion; as a result, the corrosion rate cannot be determined, and it is therefore impossible to assess corrosion resistance.

Uniform corrosion is a common form of corrosion that affects metals, and its degree of corrosion can be measured through methods such as thickness testing. Local corrosion makes it impossible to determine the location of corrosion, and thus cannot be assessed through inspection.
