摘要:
通过喷丸工艺在S30432不锈钢管内表面成功制备了塑性变形层,研究了喷丸移动速度、喷丸压力、喷丸距离对塑性变形层组织和硬度的影响。结果显示:喷丸移动速度越大塑性变形层深度越小;喷丸压力越大塑性变形层越深;随着喷丸距离的增加,塑性变形层先增大后减小;对塑性变形层深度的影响顺序为:喷丸速度>喷丸压力>喷丸距离;喷丸处理后表层硬度显著提高,比基体硬度高100HV0.5。研究表明:喷丸前进移动速度1 000 mm/min、后退速度800 mm/min、喷丸压力1.26 MPa、喷丸距离9 mm时得到的S30432不锈钢组织和性能最优。
Abstract:
The plastic deformation layer was successfully prepared on the inner surface of S30432 stainless steel pipe by shot peening. The effects of shot peening speed, shot peening pressure and shot peening distance on the structure and hardness of plastic deformation layer were studied. The results show that the greater the shot peening speed, the smaller the depth of the plastic deformation layer; the greater the shot peening pressure, the deeper the plastic deformation layer. With the increase of shot peening distance, the plastic deformation layer first increases and then decreases. The impact on depth of the plastic deformation layer is shot peening speed > shot peening pressure > shot peening distance. The hardness of the surface layer is significantly increased after shot peening, which is 100HV0.5 higher than that of the substrate. The research shows that the structure and properties of S30432 stainless steel are the best when the forward moving speed of shot peening is 1 000 mm/min, the backward speed is 800 mm/min, the shot peening pressure is 1.26 MPa and the shot peening distance is 9 mm.
