Abstract
A wear resistant coating (50) for a component of a nuclear reactor fuel assembly or control assembly comprising a ceramic material (52) which is premixed with a glass (54). The coating is applied to components of the nuclear reactor vessel, or portions thereof, which are subject to the greatest wear due to friction or fretting. Also disclosed herein is a method for enhancing the wear resistance of a portion of a metal component of a nuclear reactor by coating a surface of the component with a wear-resistant coating formed from diamond, metal nitride, or a composite of a ceramic material and a glass.
