[目的]研究离子镀铝工艺对AISI 4340钢表面完整性与疲劳性能的影响。[方法]以回火态AISI 4340钢为基材，在吹砂预处理后采用离子气相沉积(IVD)技术在试样表面制备厚度分别为10μm和16μm的铝层。利用扫描电子显微镜(SEM)、激光共聚焦显微镜(LCM)及X射线残余应力仪，对比了不同工序后试样的微观组织结构、表面粗糙度及残余应力分布。分析了离子镀铝工艺对AISI 4340钢疲劳性能的影响机制。[结果]吹砂显著提高了基材的表面粗糙度，并产生大量微坑，在受力时引发应力集中，导致材料疲劳性能大幅下降(降幅达12.2%)。经致密化处理的离子镀铝层表面形成约200 MPa的浅层残余压应力，由于镀铝层的塑性缓冲作用，该应力未对基体表面产生影响。[结论]吹砂导致的表面粗糙度增大与缺陷形成是导致AISI 4340钢疲劳性能下降的主要原因，而离子镀铝工艺对其疲劳性能的影响相对有限。
Abstract：[Objective] The effect of ion vapor deposition(IVD) of aluminum on the surface integrity and fatigue property of AISI 4340 steel needs to be studied. [Method] Using tempered AISI 4340 steel as the substrate, aluminum coatings with thicknesses of 10 μm and 16 μm were deposited on the specimen surfaces via ion vapor deposition followed by sandblasting pretreatment. The microstructure, surface roughness, and residual stress distribution of specimens at different processing stages were compared by scanning electron microscopy(SEM), laser confocal microscopy(LCM), and X-ray residual stress analysis. The influencing mechanism of aluminum IVD on the fatigue property of AISI 4340 steel was analyzed. [Result] The surface roughness of substrate was significantly increased and numerous micro-pits were formed after sandblasting, which induced stress concentration under load, leading to a substantial decrease in fatigue performance(a reduction of 12.2%). A shallow residual compressive stress of approximately 200 MPa was formed on the surface. However, due to the plastic buffering effect of the aluminum layer, this stress did not affect the substrate surface. [Conclusion] The increased surface roughness and defect formation caused by sandblasting are the primary reasons for the degradation in fatigue performance, while the ion-plated aluminum coating has a relatively limited impact on AISI 4340 steel's fatigue properties.
