MX377486B - SIMULTANEOUS ELECTRODEPOSITION PROCESS TO FORM FILMS WITH HOMOGENEOUS COMPOSITION AND UNIFORM MORPHOLOGY. - Google Patents

Abstract

The present invention refers to an electrodeposition process for forming films from a simultaneous electrodeposit or element of one or more elements with homogeneous composition and uniform morphology, which is performed in an electrolytic cell with electrodes arranged in a horizontal position, said process comprising the following steps: (a) selecting a working electrode (WE) with resistivity of p=1x10-2 0)cm or less; (b) preparing a solution containing the ions of the element or elements to be deposited, where the concentration and pH of the solution will depend on the element or elements to be deposited, so that performing the reduction of ions with the desired composition over the WE upon applying an electrodeposit potential; (c) locating the solution prepared in stage (b) inside an electrolytic cell, selecting the power source that will cause the reduction of the cations in the WE; (d) selecting the form of the potential signal to be applied to the WE; and (e) performing the elec tric connection to the electrodes and power the electrolytic cell, maintaining the cell energized until reaching the desired film thickness, where the time may vary from few seconds to several hours and the current density of the electrodeposit will depend on the following parameters: (i) the elements to be deposited; (ii) the density of the ions in the solution; (iii) the temperature of the solution; and (iv) the resistivity of the WE.
