Abstract

Procédé de placage d'argent qui comporte une première étape de pré-placage d'un substrat dans une solution aqueuse de pré-placage comprenant 10**-5 à 0,02 mole/1 d'argent et plus de 0,01 mole/1 d'un agent complexant l'argent (ions thiocyaniques) sous une densité de courant substantiellement nulle pour préplaquer une épaisseur suffisante d'argent afin de limiter ou d'empêcher un placage de substitution, et une deuxième étape de placage par électrolyse du substrat préplaqué sous une épaisseur suffisante en fournissant un courant électrique audit substrat dans une solution aqueuse d'argenture à base d'argent, d'ions thiocyaniques et d'un agent améliorateur de pellicule.
