CX-270233: High Temperature Tribological Performance of Ni Alloys Under Helium Environment for Very High Temperature Gas Cooled Reactors (VHTRs) [RC-2.3] Helium Tribology for HTGRs – Texas A&M University

Texas A&M University proposes to systematically evaluate the tribological response of 800H and 617 alloys at relevant reactor operating temperatures (700o-950oC) and in the presence of helium coolant. To achieve this objective, the project will focus on a comprehensive experimental plan to investigate and compare the friction, surface damage, and contact response to tribo-pairs consisting of alloys 800H and 617 in simulated HTGR He and also in air (room and high temperature).
