电极材料在铁磷酸盐玻璃熔体内腐蚀现象的研究

选用合金Inconel690和693作为研究对象,着重研究了它们在铁磷酸盐玻璃熔体中的腐蚀行为。分别计算了不同电极材料的尺寸损失和质量损失,以及相应的损失速率,采用SEM,EDS和XRD等手段对材料表面的腐蚀层进行了分析,确定了腐蚀层的成分,主要相组成及其晶粒形态,讨论了材料腐蚀发生的可能机理。结果表明,在玻璃熔体内,合金Inconel693比Inconel690更耐腐蚀。随着腐蚀时间的延长,合金的腐蚀速率都逐渐降低。合金试样表面的腐蚀层主要由固熔体(Fe,Cr)2O3组成。

The aspect of structural connectivity in relation toage-related gait performance

Fernandez et al.(2019).investigated the relationship between agerelated changes in attention control and gait performance in older adults.The study aimed to establish a more precise link between the influence of age on brain systems mediating executive cog-nitive functions and their relationship with gait disturbances.
