摘要 为了研究检验腐蚀对一种镍基单晶高温合金高周疲劳性能的影响,将经过标准热处理的试样置于FeCl3+HCl+H2O腐蚀剂中分别腐蚀2次和4次,采用莱卡DCM8共聚焦显微镜和扫描电镜对未腐蚀、2次与4次腐蚀试样的表面形貌进行观察,然后分别测试未腐蚀和4次腐蚀试样760℃与980℃的旋转弯曲疲劳性能。结果表明:未腐蚀试样表面存在纵向且相互平行的由抛光带来的细小抛痕,表面粗糙度低;2次腐蚀后,表面抛痕有所减少,枝晶间区域出现腐蚀坑,表面粗糙度增加;4次腐蚀后,表面抛痕被完全腐蚀掉,腐蚀坑深度和表面粗糙度进一步增加。4次腐蚀会略微降低合金760℃的疲劳性能,但对高应力幅条件下的疲劳寿命影响较大,对低应力幅条件下的疲劳寿命影响较小。4次腐蚀对合金980℃疲劳性能影响很小。

Abstract:In order to study the effects of check corrosion on the high cycle fatigue properties of a kind of nickel base single crystal superalloy, the samples with standard heat treatment were corroded twice and four times with FeCl3+HCl+H2O, respectively. Then the surface topographies of uncorroded, twice corroded and four-time corroded samples were observed with Leica DCM8 confocal microscope and SEM. After that, in ambient atmosphere, the uncorroded and four-time corroded samples were subjected to rotary bending high cycle fatigue (HCF) testing at 760℃and 980℃, respectively. The results show that the surface roughness of uncorroded samples is low, and there are many longitudinal fine scratches in parallel resulting from polishing on the surface. After twice corrosion, the scratches are reduced, the corrosion pits appear in interdendrite areas, and the surface roughness increases. After four-time corrosion, the scratches are removed completely, and the depth of corrosion pits and surface roughness further increase. The high cycle fatigue property of the alloy at 760℃ decreases after four-time corrosion, and the high stress amplitude zone is more affected than low stress amplitude zone. However, the high cycle fatigue property at 980℃ is rarely affected after four-time corrosion.
