主 题：Fretting wear Mixed fretting regime Zr alloy tube High temperature pressurized water Microstructure
摘 要：The fretting wear behavior of Zr alloy cladding tube under mixed fretting regime in a high-temperature pressurized water was *** main wear mechanism is adhesive wear,with characters of small-scale delamination at the center of worn area and serious delamination on the worn edge.A long crack throughout the worn area and other cracks propagated towards the substrate are *** cross-sectional microstructure of worn area can be divided into a thick third-body layer,thin inner oxide layer and thick tribologically transformed structure layer,and their formation mechanisms are analyzed in ***,the mixed fretting regime process and the microstructural evolution during fretting wear are discussed.
