The adhesion of electric-spark chromium coatings on 30ХГСA steel parts is studied. As shown, the adhesion of coatings depends on internal stresses of different nature: the difference of coefficients of thermal expansion of contact materials, mismatch of crystal lattices of the coating and substrate, generating mismatch stresses, and the presence of structural defects in the coating and substrate.

Key words: steel, chromium, coating, electric-spark alloying, adhesion, stress, defects.
