为研究渗铝涂层对DD6合金表面完整性和旋转弯曲高周疲劳性能的影响,采用化学气相沉积(CVD)方法在标准热处理的DD6合金疲劳试样上渗铝,采用扫描电镜(SEM)和能谱仪(EDS)分析了渗铝涂层后DD6合金试样横截面组织形貌及元素分布情况,然后分别测试未涂层和涂层后试样760 ℃与980 ℃的旋转弯曲高周疲劳性能。结果表明:渗铝涂层后试样表层区域主要分为内外两层,外层主要由β-NiAl相组成,内层为扩散层,含有较多固溶强化元素。渗铝涂层会略微降低合金760 ℃和980 ℃的旋转弯曲高周疲劳性能,但对高应力幅区的疲劳寿命影响较大,对低应力幅区的疲劳寿命影响较小。表面粗糙度差异、氧化损伤和元素互扩散等因素耦合作用是导致未涂层和涂层试样疲劳寿命差异的本质原因。 |

To investigate the effects of aluminizing coating on the surface integrity and rotational bending high cycle fatigue performance of DD6 alloy,the chemical vapor deposition method is used to aluminize DD6 fatigue samples after standard heat treatment.The cross-sectional microstructure and elemental distribution of DD6 alloy samples with aluminizing coating are analyzed using SEM and EDS,and the high cycle fatigue properties of the uncoated and coated samples are tested at 760 ℃ and 980 ℃,respectively.The results show that the surface area of the sample with aluminizing coating is mainly divided into two layers:inner and outer.The outer layer is mainly composed of the β-NiAl phase,and the inner layer is a diffusion layer,containing many solid solution strengthening elements.The aluminizing coating can slightly reduce the rotational bending high cycle fatigue performance of the alloy at 760 ℃ and 980 ℃ and has a significant impact on the fatigue life in the high-stress amplitude region and a small impact on the lowstress amplitude region.The coupling effect of surface roughness,oxidation damage,and element interdiffusion is the fundamental reason for the difference in fatigue life between uncoated and coated samples. |
