The nitrogen isotope exchange reaction was applied to measure the interfacial reaction rate constant of nitrogen with liquid cobalt at 1823 K, 1873 K, and 1923 K. Measured values increased with increasing temperature, with average values of 1.3×10⁻⁷ mol cm⁻² s⁻¹ atm⁻¹ at 1823 K, 3.3×10⁻⁷ mol cm⁻² s⁻¹ atm⁻¹ at 1873 K, and 6.2×10⁻⁷ mol cm⁻² s⁻¹ atm⁻¹ at 1923 K. Compared with liquid iron, the rate on cobalt is more than an order of magnitude smaller.

氮同位素交换法测定氮与液钴的界面反应速率常数

氮同位素交换反应用于测量氮与液钴在1823 K，1873 K和1923 K时的界面反应速率常数。测量值随温度升高而增加，平均值为1.3×10 ^-7 mol cm ^-2小号^-1个大气压^-1 1823 K，3.3×10 ^-7摩尔厘米^-2小号^-1个大气压^-1在1873 K，和6.2×10 ^-7摩尔厘米^-2小号^-1个大气压^-1在1923 K.相比对于液态铁，钴的比率要小一个数量级。
