目的
2
分析了不同超声冲击处理时间对42CrMo4钢试样横截面微观组织、表面残余应力、表面显微硬度以及耐腐蚀性能的影响。
结果
2
结果表明,超声冲击后42CrMo4钢试样表面产生了大量的塑性变形,导致硬度增加。在超声冲击8 min后,试样表面平均硬度为262.9 HV,相比于初始硬度提高了14.3%。超声冲击能够有效消除试样表面的残余拉应力,并引入残余压应力。在试验参数范围内,引入的残余压应力随着超声冲击处理时间的延长而增加。在超声冲击时间为8 min时,
x
轴向和
y
轴向的最大残余压应力分别达到-204.2 MPa和-121.5 MPa。超声冲击处理能够提高试样的耐腐蚀性能,当超声冲击时间为8 min时,试样的耐腐蚀性能最好,腐蚀电流密度下降到未处理时的12%。超声冲击通过改变金属材料的表面残余应力状态、产生晶粒细化效应、引起塑性变形等因素来改善其耐腐蚀性能。
Objective
2
The effects of different ultrasonic impact treatment time on cross section microstructure
surface residual stress
surface microhardness
and corrosion resistance of 42CrMo4 steel sample was investigated.
Results
2
The results showed that after ultrasonic impact
a large amount of plastic deformation occurred on the surface of 42CrMo4 steel sample
which results in that the hardness could be increased. After ultrasonic impact with the time of 8 min
the average surface hardness of the sample reached 262.9 HV
14.3% higher than the initial hardness. In addition
ultrasonic impact could effectively eliminate residual tensile stress on the sample surface and introduce residual compressive stress. The introduced residual compressive stress increased with the extension of ultrasonic impact tr
eatment time within the range of experimental parameters. When the ultrasonic impact time was 8 min
the maximum residual compressive stress on the
x
-axis and
y
-axis reached -204.2 MPa and -121.5 MPa respectively. The corrosion resistance of the sample can improve after ultrasonic impact treatment. When the ultrasonic impact time was 8 min
the corrosion resistance of the sample was best
and the corrosion current density decreased to 12% of the untreated sample. Ultrasonic impact improved the corrosion resistance of the metal materials by changing the residual stress state on the surface
producing grain refinement effect and plastic deformation.
