Abstract

ABSTRACT The sulfidation kinetics of titanium and Ti-6Al-4V (Ti64) using elemental sulfur were studied by measuring the amount of metal consumed instead of the change in mass or scale thickness. This metal consumption approach combines the parabolic oxidation law, Arrhenius equation, and Pilling-Bedworth ratio to determine the apparent activation energy and the pre-exponential factor of consumption of Ti64 during sulfidation. The estimations of apparent activation energy and pre-exponential factor were 110.4 kJ·mol−1 and 1.3 × 10−9 m2s−1 for the titanium-sulfur, and 116.2 kJ·mol−1 and 1.2 × 10−9 m2s−1 for the Ti64-sulfur system. Finally, a material removal predictor was developed to predict the amount of Ti64 consumed for a given sulfidation temperature and time.

钛和Ti-6Al-4V与元素硫的硫化动力学

摘要通过测量金属消耗量而不是质量或标度厚度的变化，研究了钛和Ti-6Al-4V（Ti64）使用元素硫的硫化动力学。这种金属消耗方法结合了抛物线氧化定律、Arrhenius方程和Pilling-Bedworth比率来确定硫化过程中Ti64的表观活化能和指数前消耗因子。表观活化能和指数前因子分别为110.4 kJ·mol−1和1.3 × 钛硫为10−9 m2s−1，116.2 kJ·mol−1和1.2 × Ti64硫系统为10−9 m2s−1。最后，开发了一个材料去除预测器来预测给定硫化温度和时间下Ti64的消耗量。
