中文摘要
陶瓷有望成为高性能轴承。因此,研究滚动接触疲劳强度具有重要意义。为评价喷丸强化和裂纹修复对Si3N4和Al2O3/SiC复合材料轧制接触疲劳强度的影响,对其进行了轧制接触疲劳试验。喷丸强化提高了Si3N4陶瓷的滚动接触疲劳强度。对于Al2O3/SiC复合材料,喷丸强化和裂纹修复相结合提高了其轧制接触疲劳强度。
英文摘要
Ceramics are expected as high performance bearings. So investigation of the rolling contact fatigue strength is crucially important. To evaluate the effects of the shot peening and crack-healing on the rolling contact fatigue strength, rolling contact fatigue tests were carried out on Si3N4 and Al2O3/SiC composite. For Si3N4 ceramics, the rolling contact fatigue strength was improved by shot peening. For Al2O3/SiC composite the rolling contact fatigue strength increased by combination of shot peening and crack-healing.
