Friction and Wear Characteristics of H25, H188, H214 Against Hastelloy X

ASME/STLE 2011 Joint Tribology Conference, 2011
Increasing, demand for more efficient power generation forces turbomachinery to operate at higher temperatures and compression ratios. High speeds combined with high temperatures make turbomachinery sealing applications even more challenging. In order to confirm sufficient service life, seal material pairs should be tested similar to engine operating ...

冻融作用对原状棕壤抗剪强度的影响

Shuitu Baochi Xuebao, 2021
为揭示冻融循环作用对棕壤抗剪强度的影响，采集沈阳地区5 cm和25 cm 2个深度原状棕壤（分别为H5和H25）为研究对象，通过室内冻融循环模拟和土壤直剪试验，研究冻融循环次数和土壤含水率对土壤抗剪强度的影响。结果表明：（1）土样含水率越高，初次冻融作用的破坏效果越强，1次冻融循环后，含水率为25%的H5和H25土样黏聚力分别下降50.00%和25.87%；含水率35%的H5和H25土样黏聚力分别下降75.61%和50.77%。15次冻融循环后，含水率10%的H5和H25土样黏聚力分别增加74.36 ...
