Abstract The TA2 industrial pure titanium was treated by the intermittent vacuum nitriding method. The influence of nitrogen argon ratio on the microstructures and properties of nitrided layer was investigated. The results showed that TiN and TiN_0.3 were the main phase of the substrate surface. With the decrease of nitrogen-argon ratio, the effective hardening layer depth increased, but the compactness decreased because of the rarefied nitrogen. The nitride surface and diffusion depth can be formed under an appro-priate nitrogen-argon ratio. And under this conditions, the nitrided layer and diffusion layer combined closely with gentle hardness gradient. The corrosion potential showed an upward trend which increased from -0.622 V to -0.549 V with the nitrogen-argon ratio from 1∶5 to 5∶1. However, the corrosion current and corrosion rate exhibited versa trends.

Key words： TA2 industrial pure titanium vacuum nitriding nitrogen-argon ratio
