Verbesserte dielektrische Beschichtung für an Hochtemperaturwasser ausgesetzte Oberflächen

摘要

Disclosed is a method for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method includes depositing a first or base dielectric layer (102) and a second or outer dielectric layer (104) on a conductive surface (100) that forms a portion of a high velocity flow path. The first dielectric layer material is selected to provide improved adhesion to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.
