The brittle morphologies become much more notable, and appear the inter-and trans-granular fracture mode after sodium corrosionathightemperature for both of W-specimens.
钠腐蚀后，两种钨试样的沿晶脆断特征变得更为显著，为沿晶和穿晶混合型脆性断裂。

The paper also points out that the corrosionathightemperature and the corrosion rate are related to the corrosiveness of fuel ash accumulated on heating surface and the temperature of tube wall.
并指出高温腐蚀及腐蚀速率与受热面上的结灰具有腐蚀性及管壁温度有关。

Nickel has a highcorrosion resistance to acid and alkali, rust and heat resistance athightemperature.
