Electrolytic treatment process for coating stainless steel objects

Abstract

Described is a cathodic treatment for the electrodeposition of a metal layer securely adherent to the surface of stainless steel objects in an electrolytic bath comprising one or more metals belonging exclusively to the groups from 3 to 12 of the periodic table, excluding the elements nickel, cobalt, cadmium, ruthenium, rhodium, palladium, silver, osmium, iridium, platinum, gold and rhenium, and methanesulfonic acid with a concentration of between 100 and 400 g/l. An object of the invention is also a process for applying a metal layer securely adherent to the surface of stainless steel objects, comprising a cathodic treatment as described above. Moreover, the invention further relates to an object comprising stainless steel equipped with a covering obtained by means of a process of the type described.
