Abstract
The invention concerns a method wherein the substrate () to be coated is immersed in an autocatalytic chemical deposit bath (), for example nickel, contained in a stainless steel vessel () and wherein can be optionally mixed a suspended MCrAlY alloy, so as to form a metal deposit (nickel) wherein are optionally included powder particles. The invention is characterised in that, to provide a prolonged operation of the bath, it consists in measuring with a voltmeter () the difference of potential between the substrate () and a reference electrode () immersed in the bath (), and in imposing between the substrate () and the vessel () an electric current produced by a generator (), said current being adjusted by a regulator () so as to maintain said potential difference at a selected value.
