摘要
通过Gleeble-1500热模拟机研究了在特高温度下工业纯钛的氧化行为。结果表明,随着氧化温度的升高和保温时间的延长,氧化增重持续增加：特高温氧化产生了多层氧化膜,氧通过破损的外层氧化膜通道向较致密的内层氧化膜扩散及向金属基体渗透,实现了工业纯钛的整个特高温氧化过程。
The extreme high temperature oxidation behavior of commercial pure titanium was researched by Gleeble-1500 thermal simulator. The results show that the weight gain increase continually with the increase of the oxidation temperature and the time of holding temperature. There are several oxide layers at extreme high temperature. Oxygen diffuses from the path in the cracked outer oxide layer into rather compact inner oxide layer and further into metal, which actualize the commercial pure titanium＇s oxidation at extreme high temperature.
