Abstract
The paper presents the results of two experimental series with low-temperature nitriding of VT6 titanium alloy in a non-self-maintained high-current arc discharge and in a glow discharge in different regimes. It is shown that microhardness and depth of a surface layer are significantly impacted by the temperature of treatment. The value of surface roughness of the samples is also affected, with a temperature rise from 450 to 600°C resulting in a surface roughness increase by 2–2.5 times. The temperature of nitriding affects the sign and magnitude of residual stresses in a surface layer.
