本文采用重量法和电化学法研究了镶嵌紧固件的腐蚀速率与木材含水率的关系。结果表明，在达到平台之前，腐蚀速率随含水率的增加而增加。用X射线衍射仪分析的腐蚀产物中的物相与以前的工作大体一致。观察到所有紧固件和所有条件下的均匀腐蚀，但嵌入水饱和木材中的钢质紧固件除外。为了确保用于预测木结构耐久性的湿热/腐蚀组合模型的准确性，本文提供的腐蚀速率与含水率的关系数据是必要的。
This paper characterizes the corrosion rate of embedded fasteners as a function of wood moisture content using gravimetric and electrochemical measurements. The results indicated that the corrosion rate increased with moisture content before reaching a plateau. The phases present in the corrosion products, as analyzed using X-ray diffraction, are generally consistent with previous work. Uniform corrosion was observed for all fasteners and all conditions except steel fasteners embedded in water-saturated wood. Data of dependence of corrosion rate on moisture content, presented herein, are necessary to ensure the accuracy of combined hygrothermal/corrosion models used to predict durability of wood structures.
