摘要

利用金相、XRD 和硬度分析评估了两相钛合金气体氮化的效率。结果表明，β 稳定因子越高，氮化过程中氮化物形成的强度和气体饱和度就越低。氮化效率最低的是具有最高 β 稳定因子的 VT22 高合金钛合金。分析了提高氮化效率的主要技术（热循环）和结构（初步变形或激光处理）方法。

Effectiveness of Gas Nitriding of Two-Phase Titanium Alloys

Assessment of the efficiency of two-phase titanium alloys gas nitriding was carried out using metallographic, XRD and durometric analyses. It was ascertained that the higher the β-stabilization factor, the lower the intensity of nitride formation and gas saturation during nitriding. The lowest nitriding efficiency corresponded to VT22 high-alloyed titanium alloy with the highest β-stabilization factor. The main technological (thermocycling) and structural (preliminary deformation or laser treatment) approaches to improve the nitriding efficiency were analyzed.
