| description | <p>Based on the results of X-ray diffraction analysis it has been ascertained that cathodic copper deposit precipitated from sulfate electrolyte with acrylic acid or acrylamide consist of copper crystals with considerable quantity of imperfections and crystal deformations. It has been revealed that microstress and dislocation density in the deposits increase with enhancement of organic component concentration in the solution according to symbasis dependences. Decreasing of crystallite size and increasing of structuring degree for the deposits has been observed. Peaks of any phases except copper have not been identified on X-ray diffraction pattern of the deposits. In earlier investigation it has been shown that nonmetallic component (copper π-complexes) makes up 20% of the deposits. So based on the results of X-ray diffraction investigations we can conclude that the deposit consist of copper micro crystals separated by nonmetallic component. Owing to special physical-mechanical properties of the deposits it became possible to transform them to superfine powder by means of mechanical fragmentation. Using sedimentation and microscopic analysis it has been shown that cathodic micro powders precipitated from solutions with organic compounds are homogeneous by form and dimension. Significant bactericidal and bacteriostatic effects of cathodic micro powders influence have been detected.</p> |
