摘要

为了研究等温氧化和循环氧化对钛合金氧化层生长过程的影响,在 650 ℃ 的空气中对 TC11(Ti-6.5Al-3.5Mo-1.5Zr-0.3Si)钛合金进行了高温氧化试验。氧化 300 小时后,等温氧化会形成致密的氧化层,从而提高抗进一步氧化的能力。在循环氧化过程中,氧化层呈现出针状特征,其中含有大量孔隙。循环氧化和等温氧化形成的氧化层厚度分别约为 8.6 μm 和 2.7 μm。在特定温度和氧化时间下,等温氧化过程由氧气的扩散机制控制,而循环氧化过程则由界面反应控制和氧气扩散机制共同控制。这导致循环氧化的扩散系数更大,生长动力学更快。

Effect of different oxidation modes on the growth of oxide layer of TC11 titanium alloy
In order to study the effect of isothermal oxidation and cyclic oxidation on the oxide layer growth process of titanium alloys, high-temperature oxidization tests were conducted on TC11(Ti-6.5Al-3.5Mo-1.5Zr-0.3Si)titanium alloy in air at 650 °C. After 300 h of oxidization, the isothermal oxidation causes the formation of a dense oxide layer, contributing to increased resistance to further oxidization. During cyclic oxidization, the oxide layer exhibits a needle-like feature, containing large pores. The thickness of the oxide layers formed by cyclic oxidation and isothermal oxidation are approximately 8.6 μm and 2.7 μm, respectively. Under specific temperatures and oxidizing times, the isothermal oxidation process is controlled by the diffusion mechanism of oxygen, whereas the cyclic oxidation process is controlled by a combination of the interfacial reaction control and the diffusion mechanism of oxygen. This results in greater diffusion coefficients and faster growth kinetics for cyclic oxidation.
