Phase composition, texture, and stress state in coatings based on Ti-N, Cr-N, and Ti-Cr-N systems obtained by ion-plasma deposition method are studied using an X-ray difractometry (by structural analysis) Texture and high compressive stresses up to ~ 3 GPa are revealed in all observed phases (TiN, Cr2N). Factors affecting the residual-stress level are discussed, and the model of stress-state formation is proposed.
