Abstract
The tool assembly vibrates a casing string or drill string in a wellbore. The tool assembly includes a housing, an insert mounted in the housing as a fluidic agitator, a coating on the insert, and a cover fitted over the insert. The coating on the insert provides erosion resistance and a smooth surface compatible with high velocity fluid flow required to achieve the strength and frequency of desired high strength and low frequency pressure pulses.
