Oxidation kinetics of pure tungsten (W) and tungsten-rhenium (W-Re) alloys with Re contents of 1%, 5% and 15% has been examined in the oxygen gas atmosphere at 873 K. The oxidation kinetics of the W-Re alloys were well characterized by a parabolic rate law.

During oxidation of the W-Re alloys, the Re oxide sublimated near the top surface of the oxide layer. The sublimation of the Re oxide may play roles as a sintering agent and/or a stress relief agent in the W oxide layer to be more resistant to oxidation than pure W. There will be an effective value of Re content in W oxide layers for suppression of oxidation depending on oxidation temperatures or atmospheres.

The Re oxide in the gas phase could deposit at cooler remote area on materials surface. Furthermore, the Re oxide deposits can be easily moved or transported to different area by dissolving in a water content or a moisture of flowing gas atmosphere.

在873 K的氧气气氛中研究了Re含量分别为1％，5％和15％的纯钨（W）和钨-（（W-Re）合金的氧化动力学。W-Re的氧化动力学合金具有抛物线速率定律。

在W-Re合金的氧化过程中，Re氧化物在氧化物层顶面附近升华​​。Re氧化物的升华可以充当W氧化物层中的烧结剂和/或应力释放剂，从而比纯W更具抗氧化性。W氧化物层中的Re含量有效值可用于抑制取决于氧化温度或气氛。

气相中的Re氧化物可能会沉积在材料表面较冷的较远区域。此外，通过溶解在流动的气体气氛中的水分或水分，可以容易地将Re氧化物沉积物移动或运输到不同的区域。
