Title:
METHOD OF DENSIFYING HIGH TEMPERATURE ANTI-OXIDATION COATING FOR TUNGSTEN-RHENIUM THERMOCOUPLE
Document Type and Number:
WIPO Patent Application WO/2019/109717
Kind Code:
A1
Abstract:
A method of densifying an anti-oxidation coating for a tungsten-rhenium thermocouple. The anti-oxidation coating for a tungsten-rhenium thermocouple adheres to a surface of a tungsten-rhenium thermocouple base body and includes a transition layer and an oxygen barrier layer on a surface of the transition layer. The material of the transition layer has a coefficient of thermal expansion between that of the material of the tungsten-rhenium thermocouple base body and the material selected for the oxygen barrier layer. The method includes performing isostatic pressing and heat treatment on the anti-oxidation coating for a tungsten-rhenium thermocouple.
