Abstract
The invention relates to a process for manufacturing an electrolytic bath for the production of a platinum based metallic sublayer on a metallic substrate which comprises the following steps: a) a first system comprising ligands and amine functional groups is provided said first system consisting of an aqueous solution with amine ligand comprising at least one compound X (NH) with X belonging to the group consisting of (CH,CH,CH,CH,(CH)) or NH or a salt x(NH) with x an acid radical belonging to the group consisting of (PO,HPO,HPO,HPO and HPO ,SO,HSO,CHCOO) n m and p being non zero integers b) a second system that forms a buffer system is provided c) a third system that provides a metal salt and consists of an aqueous solution with platinum is provided d) a fourth system that makes it possible to impart the conductive property to the medium is provided e) the four systems are mixed by means of which said electrolytic bath is obtained. The first system the third system and the fourth system are grouped together as a single first solution denoted by B; during step c) the third system forms a second solution denoted by A consisting of an aqueous solution with platinum IV and comprising sodium hydroxide (NaOH). During step e) the following sub steps are carried out: e1) the first solution B is covered and its temperature is brought to 50°C minimum for at least 1,h 30 min e2) the second solution A is added to the first solution B in order to form an electrolytic bath which comprises an amine platinum complex. Application to the manufacture of a metallic sublayer for a thermal barrier on a part made of a superalloy.
