Analysis of the deformation and structural characteristics of the modified cold stamping tool system “substrate-coating”

The analysis of the level of residual stresses of the third kind in the “substrate-coating” system of a cold stamping tool is carried out, depending on the nature of the structural and deformation characteristics of the preliminary cold deformation of 20X13 steel samples with a wear-resistant coating. An assessment of the nature of the intensity of changes in the values of residual stresses both in the metal of the modified samples and on the coating, depending on the PPD, was carried out.
