Nondestructive flaw detection
General corrosion refers to the corrosion on the surface of the whole metal material, which results in the overall thinning of the metal material Also known as homogeneous corrosion or uniform corrosion. When exposed to corrosive environment, the corrosion on the whole metal surface is called total corrosion. The corrosion rate of each part is close, the metal surface is thinned evenly, and there is no obvious difference in corrosion morphology. At the same time, a certain degree of heterogeneity is allowed. Therefore, the overall corrosion can be uniform or uneven.
