|초록||Sliding wear tests were performed to evaluate the effect of normal loads and wear scar sizes on the wear behavior of nuclear fuel rod in room temperature air and water. The objectives of this study are to quantitatively evaluate the wear behavior with the variation of slip amplitudes, applied normal loads and supporting spring shapes. The result
showed that the wear volume and the wear scar size increased with slip amplitude at each spring condition. The variation behavior of the volume and the wear scar size was influenced by the contact shape ofthe supporting springs. Also, it is possible to evaluate a critical ratio (Tc) at each spring shape and test condition when the T is defined as a ratio of a wear scar size (At) to applied normal load (Ln). Below this Tc, wear volume was rapidly increased and the Tc was determined by the variation of the At under the same applied normal load. Based on the above results, the wear mechanism and a evaluation method ofthe wear resistance were discussed.
