摘要:
为了探究喷丸角度¸喷丸压力等喷丸工艺参数对DC53钢表面完整性的影响,通过试验研究了不同喷丸角度¸喷丸压力对DC53钢表层残余应力场分布及硬度场分布的影响规律,同时分析了喷丸后的表面形貌及喷丸工艺参数对表面粗糙度的影响结果表明:喷丸后DC53钢引入了一定深度的残余压应力层,残余压应力随深度的增加呈现“U”型分布,当喷丸压力为0.5MPa,喷丸角度为90º时,最大残余压应力趋于稳定在约1075MPa,残余压应力层深度大约为410µm喷丸后DC53钢的表层硬度值及硬化层深度均有明显增大,当喷丸角度为90º,喷丸压力为0.55MPa时,表面硬度可由58.3HRC提高至62.4HRC,并形成了约330µm厚的硬化层喷丸后表面形貌发生明显变化,相较于原始试样,随着喷丸角度与喷丸压力的增大,表面粗糙度值先减小再增大研究结果可为DC53钢喷丸工艺参数的合理选择提供参考依据 。
Abstract:
In order to explore the influence of shot peening angle and shot peening pressure on the surface integrity of DC53 steel, the effects of different shot peening angles and shot pressures on the residual stress distribution and hardness distribution on the surface of DC53 steel are studied by experiment, and the morphology after shot peening and the effect of shot peening on roughness are analyzed. The results show that after shot peening, DC53 steel introduces a residual compressive stress layer with a certain depth. The stress shows a “U”-shaped distribution with depth increasing. When the shot peening pressure is 0.5 MPa, and the shot peening angle is 90°, the maximum stress tends to stabilize about 1 075 MPa, and the stress layer depth is about 410 μm. The surface hardness value and hardened layer depth of DC53 steel after shot peening are obviously increased. When the shot peening angle is 90° and the shot peening pressure is 0.55 MPa, the surface hardness increases from 58.3 HRC to 62.4 HRC,and a hardened layer of about 330 μm is formed. The surface morphology changes significantly after shot peening, compared with the original specimens, the surface roughness value decreases first and then increases with the increasing of the shot peening angle and shot peening pressure. The research results can provide a reference for the reasonable selection of shot peening parameters of DC53 steel.
