摘要

研究了锆合金覆层管在大滑移机制（GSR）下与凹槽配接的摩擦磨损行为的演变。研究结果表明，GSR 条件下的主要磨损机制是分层、表面疲劳磨损和磨料磨损，而摩擦磨损率主要取决于分层。磨损区域的横截面微观结构可分为第三体层、摩擦转化结构层和一般变形层，并对其形成机理进行了分析。此外，还确定了磨损诱导晶粒细化的机制为动态再结晶（DRX），包括连续再结晶和不连续再结晶。此外，还讨论了摩擦磨损和 DRX 的过程。

Evolution of fretting wear behavior of zirconium alloy cladding tube under gross slip regime in simulated primary water of pressurized water reactor

The evolution of fretting wear behavior of zirconium alloy cladding tubes mated with dimples under the gross slip regime (GSR) was investigated. The findings revealed that the primary wear mechanisms under GSR were delamination, surface fatigue wear and abrasive wear, and the fretting damage rate mainly depends on delamination. The cross-sectional microstructure of the worn area could be divided into the third-body layer, tribologically transformed structure layer, and general deformation layer, with their formation mechanisms analyzed. Furthermore, the mechanism of wear-induced grain refinement was identified as dynamic recrystallization (DRX), including both continuous DRX and discontinuous DRX. Additionally, the processes of fretting wear and DRX were discussed.
