表面制备SiO2涂层的Ti2AlNb基合金高温氧化激活能研究
Activation Energy of Oxidation of Ti2AlNb Alloy Deposited SiO2 Coating
摘要
Abstract
Amorphous silica coating was deposited on a Ti2AlNb alloy by sol-gel method.The kinetic data of oxidation mass gain was measured for coated and blank samples at 800℃ and 900℃ in air,and the oxidation rate constants at different temperatures were determined by the relevant linear fitting.According to Arrhenius relation of the oxidation rate constants,the activation energy of oxidation was derived for these samples at 800 ℃ and 900 ℃.It is found that the oxidation rate constant of coated sample is lower than the blank one and the value of activation energy of oxidation of coated sample is higher than the blank sample.关键词
