有机防腐涂层在流动条件下的加速失效行为

魏英华 , 张立新 , 柯伟

中国腐蚀与防护学报

选用熔融结合环氧粉末(FBE)涂层作为研究对象,用电化学阻抗谱法(EIS)考察流动的和静止的涂层在3% NaCl溶液介质中的失效行为,以此探讨流动条件对涂层的失效行为的影响.结果表明,涂层在流动的条件下加速失效,失效的原因是液体的流动加速了溶液中离子,而不是水分子向涂层中的渗透.这为考核涂层提供了一...

Flow instability of molten GaAs in the Czochralski configuration

Shuxian CHEN

材料科学技术(英文)

The flow and heat transfer of molten GaAs under the interaction of buoyancy, Marangoni and crystal rotation in the Czochralski configuration are numerically studied by using a time-dependent and three-dimensional turbulent flow model for the first time. The transition from axisymmetric flow to non-a...
