In this paper, the fretting wear characteristics of INCONEL 690 (I-690) and INCONEL 600 (I-600) was evaluated to verify the wear mechanism and the wear life. Because of the excellent corrosion-resistance of nickel-based alloy, those materials are used for steam generator tube in nuclear power plants. Sometimes the tubes are damaged due to small amplitude vibration, so called fretting wear. To verify the fretting wear mechanisms the wear experiment was carried with the crossed-cylinder wear tester, which used a cam to oscillate the specimen. The test was carried out at loads of 40N and 90N in elevated temperatures of water. The temperatures of water were 20°C, 50°C and 80°C. The increase of water temperature causes the oxidation of the contact area to be delayed, and the amount of wear on oxide layer to be reduced. The main wear mechanisms of fretting were abrasive wear and oxidation wear.

In this study, fretting wear behavior of NC30Fe tubes against 1Cr13 stainless steel cylinder in distilled water and hydrazine solution was investigated at room temperature. Wear scar was analyzed systematically by NanoMap500DLS dual-mode profilometer, SEM, EDX. The results showed that the fretting logs were running in slip regime. The hydrazine solution may lead to corrosion. The friction coefficient in aqueous medium was lowered obviously, but it in distilled water was lower than that in hydrazine solution due to the effect of hydrazine solution. The wear was lightened in aqueous medium significantly, but it was more severe in hydrazine solution than that in distilled water for the reason of hydrazine solution. The abrasive wear, friction oxidation and delamination were the main wear mechanisms of NC30Fe in ambient. However, in aqueous medium the abrasive wear and delamination were the main wear mechanisms of NC30Fe.

The objective of this study is to provide qualitative impact/fretting wear information for heat exchanger tubes through the performance of a series of tests involving the pertinent parameters: force between the tube and its support; tube to support plate hole clearance; tube support plate thickness; preload; and tube vibration frequency. The characteristics of impact/fretting wear relative to material combinations and fluid environment were also investigated. The test apparatus consists of a cantilevered tube with a simulated tube support plate at the “free end.” Tube vibration is induced by an electromagnetic exciter to simulate the flow-induced tube motion occurring in a real heat exchanger at the tube/tube support plate interface. Tests are conducted in air, water, and oil, all at room temperature. Removable wear rings are attached to the tube free end and simulated support fixture. Wear ring materials include carbon steel, 304 stainless steel, Inconel 600 and brass. Wear is measured by a weight loss technique and wear rates are calculated and reported as functions of the various pertinent parameters. Based on the test results, general conclusions are drawn.
