实验室进行腐蚀试验总想在一个相对较短时间内获得实验数据。为此,常采取某些措施来强化试验的苛刻性。在应力腐蚀试验中,有下列几种加速途径:改变介质的成份、温度或压力来增加环境的相对侵蚀性;应用恒电流或恒电位来加速腐蚀反应;改变合金的成份或组织,以提高合金对SCC敏感性;试样开缺口或予制裂纹等等。除此之外,在应力腐蚀试样上加上一慢动应变,也属于这一范畴。正象用予制疲劳裂
Laboratory corrosion test always want to get experimental data in a relatively short period of time. To this end, often take some measures to enhance the rigor of the test. In the stress corrosion test, there are several ways to accelerate: changing the composition, temperature or pressure of the medium to increase the relative corrosiveness of the environment; applying a constant current or constant potential to accelerate the corrosion reaction; changing the composition or the structure of the alloy to improve the alloy Sensitivity to SCC; Specimens are notched or pre-cracked, etc. In addition, stress-corrosion specimens with a slow strain, also belong to this category. As with the system of fatigue
