利用自行设计的高温微动磨损试验机，在285 ℃空气中对690合金管材/405不锈钢板材进行了不同微动循环次数的微动磨损试验。结果表明，第三体层（TBL）的形成对690合金管材的微动磨损性能有显著影响。界面之间存在TBL保护了部分690合金管表面免受损坏。因此，它导致了不连续的磨痕和摩擦系数（COF）降低后，约500个周期。由于过渡层和氧化层交替出现，氧、铬和铁的含量沿TBL厚度方向沿着呈现明显的分层现象。
The fretting wear tests of 690 alloy tube/405 stainless steel plate under various fretting cycles have been conducted in 285 ℃ air using a self-designed elevated-temperature fretting wear rig. The results demonstrated that the formation of third body layer (TBL) had considerable influence on the fretting wear performances of 690 alloy tube. The presence of TBL between the interfaces protected the partial 690 alloy tube surface from being damaged. Consequently, it resulted in the discontinuity of wear scar and reduction of coefficient of friction (COF) after approximately 500th cycles. Along the thickness of TBL, the contents of oxygen, chromium and iron took on obvious stratification induced by alternating the transfer layer and oxidation layer.
