GH4169高温合金涡轮盘表面径轴向裂纹的渗透检测可行性
Feasibility of Penetrant Testing on Surface Axial-Radial Cracks of GH4169 Super Alloy Turbine Disk
摘要
Abstract
The post emulsifiable and water-washable fluorescent penetrant testing were carried out with ZL-27A and ZL67 respectively. Ultrasonic cleaning by detergent were used for 30 minutes before penetrant. The parts were immersed and drained for 60 minutes. The macroscopic and microscopic characteristics of cracks were researched using the split mirror and scanning electron microscope. The re-sults show that the outgrowth of high temperature oxidation plugs up the forging cracks. Thus the penetrant testing is not effective in de-tecting this type of cracks.关键词
