Electroplating bath for electroless electroplating for the formation of a nickel alloy - coating with a high phosphorus content

摘要

a galvanisierbad to stromlosen galvanising for formation of a coating of a nickel - phosphorus alloy with high phosphorus content, contains water as a reducing agent for nickelionen, hypophosphit nickelionen, a means to adjust the ph, a ph puffersubstanz,a small amount of a means for reducing mechanical stresses and tri (alkalimetall) - n - (2 - hydroxyethyl) - ethylendiamin - n, n ', n' - triacetat as first phosphorabscheidungspromotor. the galvanisierbad may also at least a second phosphorabscheidungspromotor sulfate from ammonium sulphate, potassium sulphate and sodium sulphate lithiumsulfat, is selected.
