Evolution of wear damage in 690 alloy tube mated with 405 stainless steel plate due to fretting conditions

Abstract A running condition fretting map of 690 alloy tubes against 405 stainless steel plates was established through various fretting tests at room temperature. Three fretting regimes were observed: partial slip regime (PSR), mixed regime (MR), and gross slip regime (GSR). In the PSR, slight damage associated with the lowest friction coefficient (COF) and an adhesion layer due to adhesive wear were detected. In the GSR, severe damage corresponding to a higher COF and delamination were observed. In the PSR, Fe2O3 may be one of the main components of the wear particles. The spinel oxides of NiCr2O4 and/or FeCr2O4 may have existed in the debris layer in the MR and GSR.
