Investigation of the citrate solution (contain cobalt sulfate 0,2M and sodium tungstate 0,2M) electroconductivity for obtaining of cobalt – tungsten coating is carry out. It is search out significant decreasing in time of this solution conductivity in comparison with aqueous and citrate complexes of cobalt. It was show that observed changes conditioned by generation of mixed heteronuclea complex (probably polymeric) in solution. The fractionation of solution with gel filtration show that all changes was caused by transformation of substance with high molecular weight. |
