摘　　要：以化学反应动力学为基础,利用重量法测试了TiO2热喷涂层在ClO2水溶液介质中的腐蚀速度,从而求出了TiO2热喷涂层的单位厚度寿命。实验表明,TiO2热喷涂层在ClO2水溶液中的腐蚀速度满足VL=kc1.1(mm/a)的动力学方程式,从而为TiO2热喷涂层在ClO2水溶液中的防腐蚀提供了理论依据。Based on chemical reaction knetics,the corrosion rate and lifetime of TiO 2 thermal spraying coating in ClO 2 liquid medium were measured by means of weight law.The research results showed that TiO 2 thermal spraying coating corrosion rate meet chemical kneties equation of V L =KC 1.1 (mm/a)and the constant of corrosion reaction rate K=128exp(-30842.88/RT).It provided the theory for erosion resistance of TiO 2 thermal spraying coating in ClO 2 liquid medium.
