If the intensity of erosion is found to be around 0.1 watt/sq.m. or less, then one of the following methods of protection should be effective: substitution of a more resistant material, either for the entire component or at critical areas in the form of either inlays or overlays; use of elastomeric coatings; cathodic protection; or air injection. In the intermediate intensity range from about 0.1 to 1 watt/sq.m., it may be possible, in addition to one or more of the above, to sufficiently reduce the rate of damage by imposing operational limitations on velocity, power, or pumping capacity. In many cases it has been found that the intensity of erosion is proportional to the velocity raised to an exponent of six or greater. Intensities of erosion above 1 watt/sq.m. will ususally require major design changes.
