The role of dispersed phase in the formation of Ni – CEC

Abstract

Abstract Composite electrochemical coatings make it possible to successfully solve many practical problems of surface hardening of structural parts, tooling and restoration of their wear parts. One of the factors influencing the structure and properties of composite coatings is characteristics of the dispersed phase (nature, concentration, dispersion). This paper presents the results of studying activation of titanium carbide by heat treatment method, which contributed to an increase in the main characteristics of nickel electroreduction. Barium sulfate is a promising dispersed material for composite coatings. This powder can be obtained with any dispersion as a result of an exchange reaction. In this work investigates the effect on the particle size of barium sulfate deposition conditions (time of mixing and pouring of reagents). The optimum conditions for obtaining barium sulfate are determined. Both powders can be used as a dispersed phase to obtain composite coatings with a nickel matrix.
