A procedure of an article be electroplated Chromium layer with a thickness of more than five microns

摘要

An article with a procedure to be electroplated Chromium Layer thicker than 5 micrometres using a galvanoplastica solution of Trivalent Chromium. Prepare two Aqueous Solutions of a Balanced triocianatocromo (Complex III), one with a relatively low concentration of Chromium, lower than 0.03 m.Both solutions were added Chromium amino acid that acts as a buffer material and one of them will add a Wetting Agent.The article to be coated with Chrome Coating is introduced first in the solution of Lower concentration of Chromium, to form a thin film, usually of a thickness not exceeding 0.1 micrometers; then it introduces the solution of high concentration of Chromium, where the pel Initial icula Chromium is added the rest of the thickness.Also the remaining thickness of the Chrome Layer can be deposited Alternately, from successive immersions in Solutions of high Chromium and low concentration encapas, thick and thin. The current densities in both bathrooms are located at intervals of 40 to 50 and 50 to 120 mA / cm.cuadrados, respectively.
