摘　　要：超声振动滚挤压技术作为一种新型的高能表面强化技术,不仅可以有效的提高金属表面的完整性,还可以改善金属零件的耐疲劳性能。本文选取了45钢金属材料作为实验研究的对象,使用超声振动滚挤压技术作用于钢金属的表面,通过详细的对比看出,金属零件的表面显现出来一些纤维化的情况,导致金属零件表面出现这种纤维化,与超声波的振动幅度、挤压都有很大的关系。振动幅度越大,挤压速度越快,金属零件表面纤维化的程度就越明显。As a new high-energy surface strengthening technology,ultrasonic vibration rolling and extrusion technology can not only improve the integrity of metal surface,but also improve the fatigue resistance of metal parts.In this paper,45 steel metal material is selected as the experimental research object,and ultrasonic vibration rolling extrusion technology is used to act on the surface of steel metal.Through detailed comparison,it can be seen that the surface of metal parts shows some fibrosis,which leads to the appearance of this kind of fiber maintenance on the surface of metal parts,which is closely related to the vibration amplitude and extrusion of ultrasonic.The larger the vibration amplitude,the faster the extrusion speed,the more obvious the degree of the surface fibrosis of the metal parts.
