Speed of deposition in brass bath [Brazil] 

+++ Which are the conditions of work of a brass bath to get a good speed of deposition in brass bath high layer? Diogo Cavalcanti Home Hardware - Caxias do Sul, RS, Brasil +++ Hi. The single thing that must be done to increase the speed, according to Faraday's Law, is to increase the current density. But how to achieve this, while avoiding consequent problems like burning, is difficult to discuss in the abstract. Are you using a cyanide or non-cyanide brass plating bath, Diogo?
