Intensification of electrochemical restoration of agricultural machinery parts through mass transfer control

Abstract

This paper examines the main mechanisms of mass transfer during the electrochemical restoration of worn agricultural machinery parts. The influence of diffusion, migration, and convection on the supply of ions to the cathode surface and the formation of the restoration layer is demonstrated. The relationship between the hydrodynamic regime, current density, temperature, and electrolyte concentration with the stability of electrodeposition is established. The feasibility of mass transfer control for improving coating uniformity and the productivity of restoration is substantiated.
