Evaluation of Material Wear and Self-Welding in Sodium-Cooled Reactor Systems

Laboratory and prototype component tests were made to determine the degree of adhesion and self-welding of various bearing-couple materials in liquid sodium. A few tests were run in nitrogen and in argon. Temperatures were from 500 F to 1000 F and the static loads on the bearing surfaces were up to...

Description
Summary:Laboratory and prototype component tests were made to determine the degree of adhesion and self-welding of various bearing-couple materials in liquid sodium. A few tests were run in nitrogen and in argon. Temperatures were from 500 F to 1000 F and the static loads on the bearing surfaces were up to 10,000 psi. The harder materials showed better wear resistance generally than did the softer materials. However, each material has a service life depending upon the temperature, unit loads, nature of service, and environment.
