随着材料试验技术的发展,液相腐蚀疲劳试验技术也迅速发展起来了。由于目前国内尚未生产专用的腐蚀疲劳试验设备,给进行腐蚀疲劳试验造成困难。能否在一般的疲劳试验机上加一腐蚀装置来进行腐蚀疲劳试验呢?基于这种想法,我们在轴向疲劳试验机和纯弯曲疲劳试验机上进行改进。几年来的实践,证明这种方法是可行的。一、轴向腐蚀疲劳试验装置 1.轴向腐蚀疲劳装置(图1)
With the development of material testing technology, liquid corrosion testing technology has rapidly developed. Due to the fact that no special corrosion fatigue test equipment has been produced in China at present, it is difficult to test the corrosion fatigue. Can we add a corrosion device to the general fatigue testing machine to carry out the corrosion fatigue test? Based on this idea, we improve on the axial fatigue testing machine and the pure bending fatigue testing machine. Years of practice prove that this method is feasible. First, the axial corrosion fatigue test device 1. Axial corrosion fatigue device (Figure 1)
