摘    要:研究了K417镍基高温合金的微动磨损行为。结果表明,K417镍基高温合金的微动磨损可以分为开始、过渡和稳定三个阶段,稳定阶段的微动磨损机理是疲劳脱层。高温下K417镍基合金的微动磨损表面可以形成致密的釉质氧化膜,具有良好高温强度的K417镍基合金基体的支撑保证了釉质氧化膜的连续和完整。通过降低剪切应力的大小和改变其分布形式,釉质氧化膜可以缓解K417镍基合金的微动磨损。

关 键 词:镍基高温合金  微动磨损  磨损机理  疲劳脱层  釉质氧化膜

Study of fretting wear behavior of K417 nickel base superalloy
Abstract:Fretting wear behavior of K417 nickel base superalloy was investigated. The results show that process of fretting wear of K417 nickel base superalloy could be divided into three stages that are initiation, transition and stabilization stage. Mechanism of fretting wear is mainly fatigue delamination at steady stage. At high temperature, dense glazing oxide film could be formed at the wear surface of the K417 nickel base superalloy. Because of excellent high temperature strength K417 nickel base superalloy could sufficiently support glazing oxide film and make it continuous and integrate. Glazing oxide film that could decrease shear stress and change its distribution could alleviate fretting wear of K417 nickel base superalloy.
Keywords:nickel base superalloy  fretting wear  wear mechanism  fatigue delamination  glazing oxide film
