Fretting wear of a nitrided 316L/304L contact subject to in-phase normal force fluctuation in dry and lithium-boron solution: An R-P-friction energy wear approach

摘要

In nuclear power plants, tubes of the rod cluster control assemblies undergo impacts at low contact pressures against guides, causing specific wear on the contact surfaces. The present study investigates fretting wear behavior under variable loading, using an original double-actuator fretting wear system which allows independent control of tangential sliding and normal force fluctuation. Using this test system the fretting wear response of a nitrided 316L SS cylinder fretted against a 304L SS plate in air and in a lithium-boron solution is investigated.
