Protected Graphite Materials for High Temperature Industrial Applications

点击翻译按钮获取中文摘要

The strong chemical reactivity of graphite in oxidizing environments at elevated temperatures requires that graphite surfaces be protected in use as a structural material. Techniques will be investigated for modifying the surface chemistry of graphite, for developing new approaches for the impregnation of graphite, and for coating graphite parts with protective ceramic coating layers. New electrochemically-based processes which take advantage of the high electrical conductivity of graphite will be developed.
