Abstract
A method for impregnating a stator of a progressive cavity assembly with nanoparticles. The assembly comprising a stator having an inner core formed on its inner surface, the inner core defining a groove. A primary rotor is disposed within the groove. In operation, the primary rotor is removed from the stator, and a plurality of nanoparticles are distributed throughout the groove. A work rotor is installed within the groove and rotated at a high rate so as to press the nanoparticles into the inner core. The work rotor is removed from the stator and the primary rotor is re-installed into the stator.

A method, comprising:
- providing a stator comprising an inner surface and an inner core formed on the inner surface and defining a groove;
- and
- distributing a plurality of nanoparticles within the groove.
A method of treating a tubular stator having an internal elastomeric substrate within which at least one helical groove is formed, comprising:
- distributing nanoparticles within the at least one groove;
- and
- coating the at least one groove by pressing the distributed nanoparticles into the substrate.
