Abstract
Si introducono additivi diversi per differenziare chimicamente sia i bagni di trattamento che i rivestimenti di conversione chimica. la differenziazione si ottiene mediante aggiunta ai bagni di cromatazione o fosfocromatazione standard uno o più dei seguenti metalli, sotto forma di Ossidi, Acidi o sali derivati: Titanio, Vanadio, Manganese, Cobalto, Nichel, Argento, Afnio, Tungsteno. L'identificazione del processo di trattamento che ha prodotto un determinato particolare è effettuato preferibilmente con analisi non distruttive (Microanalisi superficiali) dei particolari trattati.Different additives are introduced to chemically differentiate both the treatment baths and the chemical conversion coatings. the differentiation is obtained by adding one or more of the following metals, in the form of Oxides, Acids or derivative salts, to the standard chromation or phosphochromation baths: Titanium, Vanadium, Manganese, Cobalt, Nickel, Silver, Hafnium, Tungsten. The identification of the treatment process that produced a particular detail is preferably carried out with non-destructive analysis (surface microanalysis) of the treated details.

_ Si deve innanzitutto rilevare che per cromatazione 0 fosfocromatazione si intende un rivestimento di conversione chimica rispettivamente a base di cromato di cromo 0 fosfato di cromo. Tale rivestimento si ottiene mediante trattamenti ir bagni. _ First of all, it should be noted that by chromating or phosphochromatizing is meant a chemical conversion coating respectively based on chromium chromate or chromium phosphate. This coating is obtained by means of bath treatments.
