| Popis: | By using the electrodeposition method, composite Sn-inorganic coatings have been obtained. As the inorganic compounds, ultrafine PbMo6S8, NbCxNy, TixNy, and Ti0.63Nb0.34C0.38N0.58 powders were utilized. The Sn–PbMo6S8 coatings containing 28-88 wt.% PbMo6S8 were superconductive. The highly electroconductive Sn–NbCxNy coatings containing 1-88 wt.% of the disperse phase and the Sn–TixNy coatings with 42-70 wt.% TixNy were structurally stable at a low temperature (−50°C), solderable, and corrosion resistant on copper. The formation of the structure of the coatings is determined by the electrolyte composition, the cathode current density during the electrolysis, and the codeposition of the disperse phase. By electrodeposition of the chromium carbonitride Cr3C1.6N0.4, in the presence of H4P2O7 in an CrO3-based electrolyte, mat composite Cr–Cr3C1.6N0.4 coatings with 6.8 wt.% Cr3C1.6N0.4 were obtained, which had a finely uneaven surface structure. Such surfaces are needed in the cases where lubricants are used. |
