Abstract

The influence of the parameters of thermal, electrochemical, and microarc oxidation on the laws of formation of oxide barrier coatings on a VT23 titanium alloy (Ti–Al–V–Mo–Cr–Fe system) is studied. The resistance of the formed coatings to the subsequent vacuum annealing at 800°C for 1 h is examined. The coating thickness is shown to increase with the oxidation temperature or voltage. The coatings produced by thermal and microarc oxidation are most resistant to heating in vacuum, but those produced by microarc oxidation contain pores. The anodic oxide coating is completely dissolved upon vacuum annealing.

VT23 钛合金上抗氢渗透氧化物阻挡层的形成

摘要

研究了热、电化学和微弧氧化参数对VT23钛合金（Ti-Al-V-Mo-Cr-Fe系）氧化物阻挡层形成规律的影响。检查形成的涂层对随后在 800°C 真空退火 1 小时的耐受性。涂层厚度随着氧化温度或电压的增加而增加。热氧化和微弧氧化产生的涂层最耐真空加热，但微弧氧化产生的涂层含有孔隙。真空退火时阳极氧化层完全溶解。
