The oxidation kinetics of depleted uranium was studied in pure oxygen pressure of 5 kPa at below 100°C by using spectroscopic ellipsometry. The relationship of the thickness of uranium oxide with time is measured. The results indicate that below 100°C in the initial period, the relationship between oxidation layer thickness and time is parabolic. The oxidation mechanism of depleted uranium is discussed and the active energy of depleted uranium at given experimental conditions is 87.165kJ/mol from calculation.

采用椭偏技术研究了45~95℃和5kPa纯氧气氛中金属铀的氧化，通过不同温度下金属铀表面氧化层厚度随时间的变化规律，得到贫铀在初始氧化阶段的表面氧化层厚度与时间的关系均呈现抛物线规律；绘制出了在不同温度下金属铀表面的氧化动力学曲线，由此得到在低于100℃，5kPa的纯氧气氛下贫铀表面形成氧化物的反应活化能为87.165kJ/mol。

Arc-glow plasma depositing technique is a new surface coating method. With the help of vacuum arc discharge, a cold cathode arc source continually emits ion beams of coating elements with high currency density and high ionizing ratio.Upon the ion bombard and diffusion work on, the surfaces of the parts form deposited layers, diffusion layers. In this study, a commercial magnesium alloy AZ91 was coated with Ti film layer.
