Impingement Corrosion

Recognition of Impingement Corrosion

What is Impingement Corrosion? Impingement corrosion is a form of erosion-corrosion generally associated with the local impingement of a high velocity, flowing fluid against a solid surface.

Impingement corrosion usually produces a pattern of localized attack with directional features.

The mechanism of impingement is similar to that of erosion-corrosion, as flow removes the protective films responsible for the corrosion resistance of the material.

Other damage mechanisms related to Impingement Corrosion include:

Flow accelerated corrosion (FAC)

Cavitation Damage

Erosion corrosion

How to prevent Cavitation Damage?

In general, cavitation damage can be prevented by the techniques used in preventing erosion corrosion. Also, there are some specific measures. Cavitation damage can be reduced by changing design to minimize hydrodynamic pressure differences in process flow streams.
