ACTUAL METHODS OF ELECTROCHEMICAL SURFACE TREATMENT

Abstract

In this work, we have studied the methods of electrochemical processing of materials in order to give them new functional properties. Experimental data on the production of corrosion-resistant coatings based on Zn-Ni and Zn-Co alloys from ammonium oxalate electrolytes and the study of their protective properties are presented. The questions of electrochemical production of carbon nanomaterials by anodic exfoliation of graphite in sulfuric acid electrolytes are considered. The influence of the dispersed phase of electrochemically exfoliated graphite on the electrodeposition of tin from sulfate and stannate electrolytes has been established. The influence of the additive on the aging of tin coatings and their ability to solderability was studied. Data are given on the effect of chloride ions in a solution of chemical polishing of brass on solderability. For citation: Shekhanov R.F., Gridchin S.N., Bratkov I.V., Ershova T.V., Dontsov M.G.
