Abstract: An electrodeposition process for electrodeposition of a metal on a metal part (1), includes the connection of the metal part (1) to be treated to a first electrical pole of a current generator and a second pole opposite the first pole connected to the electrolytic medium through an electrode (3), and includes relative movement of the metal part (1) in relation to a set of free solid particles (4) that retain a conductive solution. The solution includes metal cations of the metal to be deposited charged with a positive electrical charge in a non-conductive environment (5) that causes the reduction of the metal cations of the conductive solution on the surface of the metal part to be treated (1). An electrolytic medium for electrodeposition of a metal on a metal part (1) is also provided.

Abstract: An electrolytic medium is provided to the treatment of metallic surfaces and includes solid particles and a non-conductive fluid, the process that uses said medium and the device to carry out the process.
