Abstract
The paper justifies the usefulness of preliminary ion implantation before forming the protective coating by magnetron sputtering in order to improve its adhesion and hence the coating durability. The important characteristics of coatings include the adhesion force and energy. To select the optimal modes of coatings formation, materials and equipment it is proposed the theoretical method of the adhesion force calculation in binary metallic systems. The adhesion force and energy depend on the elemental distribution in the depth of the coating and on the single bond force as in the substrate and in the coating. In addition the adhesion force is also determined by the coefficient taking into account the reduction of the possible bond number and depending on the surface purity and the structural defects presence. The developed model includes all of the above factors. The elements distribution over the depth of the coating was estimated using a kinetic model of mass transfer by vacancy mechanism. The paper presents the results of the adhesion force calculation for the chromium coating on the surface of A21382 steel.
