腐蚀疲劳裂纹扩展 meaning in Chinese
corrosion fatigue crack propagation
Examples
- Approximate calculation of crack propagation rate of metal corrosion fatigue
金属腐蚀疲劳裂纹扩展速率的近似计算 - The composition and modality of the environment medium play an important role in the crack growth of corrosion fatigue
环境介质的组成、形态是影响腐蚀疲劳裂纹扩展的重要因素。 - The formation of 3 . 5 % nacl solution is almost similar to that of 3 . 5 % nacl thin electrolyte layer , just the mass transfer rate of the oxygen in the layer is more quicker than in the solution ? the test shows that the crack growth rate of wet - corrosion fatigue of lc4cs aluminum alloy in the layer is quicker than in the solution , and also shows that morphology of fatigue fracture in the layer is evidently distinguished from in the solution
3 . 5 nacl溶液和3 . 5 nacl薄液层的化学组成几乎完全相同，只是薄液层中氧的传质速率较快。实验结果显示了在薄液层中， lc4cs铝合金的湿腐蚀疲劳裂纹扩展速率，大于在3 . 5 nacl溶液中的速率。实验还发现其疲劳断口的形貌，也与3 . 5 nacl溶液中的有明显区别。 - Furthermore , the supposition of galvanic couple is drawn into the procedure of corrosion fatigue crack growth of aluminum alloys , the relation of couple current vs loading time is determined with electrochemical methods . a formula in the theory is deduced which expresses the stress corrosion crack growth rate of lc4cs aluminum alloy , the results of mathematical modeling preferably correspond with examination
再将“耦合作用”的猜想，引入铝合金的腐蚀疲劳裂纹扩展过程中，用电化学的方法测定耦合电流与加载时间的关系，并从理论上导出lc4cs铝合金应力腐蚀裂纹扩展速率的数学表达式，数学模拟的结果与实验值具有较好的一致性。
