Title:
HIGH TEMPERATURE ANTI-OXIDATION COATING FOR TUNGSTEN-RHENIUM THERMOCOUPLE AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/109752
Kind Code:
A1
Abstract:
Provided is a high temperature anti-oxidation coating for a tungsten-rhenium thermocouple, comprising a transition layer directly on a surface of a tungsten-rhenium thermocouple base body and an oxygen barrier material 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 oxygen barrier material. Also provided is an application of the anti-oxidation coating.
