Conclusions
Nitriding of α-, pseudo-α- and α+β-Ti alloys forms diffusion layers consisting of a nitride layer and a gas-saturated layer. In α+β-Ti alloys, a third additional transient zone forms. During the nitriding process, redistribution of the alloying elements present in the alloys takes place, which is caused by their differing affinities for nitrogen.
Nitriding schedules also have an effect on the alloying element redistribution. Nitriding temperature or time increase causes either thickening of the diffusion layer zones or formation of a qualitatively new structure in them.
