Time-dependent wear behavior of alloy 690 tubes fretted against 405 stainless steel in high-temperature argon and water

Fretting wear caused by flow-induced structural vibrations is a concern in the nuclear industry. The wear behavior of alloy 690 steam generator (SG) tube fretting against AISI 405 stainless steel, and exposed to 285 °C water and argon, was investigated using a fabricated apparatus. Compared with argon, high temperature water contributes to the removal of wear particles and the formation of oxide scale on the wear scar. Fretting promotes...
