目的
2
为解决42CrMo4钢(常用于承受动态载荷的机械部件)因残余拉应力导致寿命降低、且在恶劣环境下易受腐蚀的问题,探究了超声冲击处理对其表面残余应力与电化学性能的调控作用。
方法
2
首先,采用0、4、8 min超声冲击处理(电流2.0 A、频率40 kHz)42CrMo4钢试样。其次,通过超景深三维数字显微镜表征其微观组织,通过显微硬度计测试其显微硬度。然后,采用小孔法测量其残余应力。最后,利用三电极体系(3.5%NaCl溶液)测试其电化学性能(极化曲线、阻抗谱)。
结果
2
结果表明,超声冲击使试样表面产生塑性变形与晶粒细化;采用超声冲击8 min时试样表面平均硬度达262.9 HV(较初始值提升14.3%),残余拉应力转为压应力且随处理时间增大,
x
、
y
轴向最大残余压应力分别为-204.2、-121.5 MPa,腐蚀电流密度降至未处理试样的12%,耐腐蚀性能最优。晶粒细化、塑性变形及残余压应力的协同作用是性能提升的关键机制。
Objective
2
To solve the problems that 42CrMo4 steel (commonly used in mechanical components bearing dynamic loads) has reduced service life due to residual tensile stress and is susceptible to corrosion in harsh environments
the regulatory effect of ultrasonic impact treatment on its surface residual stress and electrochemical properties was investigated.
Methods
2
Firstly
42CrMo4 steel samples were treated with ultrasonic impact for 0
4
and 8 minutes (current 2.0 A
frequency 40 kHz). Secondly
their microstructures were characterized by a ultra-depth-of-field 3D digital microscope
and their microhardness was tested by a microhardness tester. Then
their residual stress was measured by the small hole method. Finally
their electrochemical properties (polarization curves
impedance spectra) were tested using a three-electrode system (3.5% NaCl solution).
Results
2
The results showed that ultrasonic impact caused plastic deformation and grain refinement on the surface of the samples;at 8 minutes
the average surface hardness reached 262.9 HV (14.3% higher than the initial value)
the residual tensile stress was converted to compressive stress and increased with treatment time
and the maximum residual compressive stresses in the
x
and
y
axes at 8 minutes were -204.2 MPa and -121.5 MPa
respectively;at 8 minutes
the corrosion current density was reduced to 12% of that of the untreated sample
showing the best corrosion resistance. The synergistic effect of grain refinement
plastic deformation and residual compressive stress was the key mechanism for performance improvement.
