Silver Plating - an overview ScienceDirect Topics
Cyanide silver plating processes have many advantages which are that cyanide is an excellent complexing agent; cyanide silver plating solutions produce a pleasing pure white excellent adhesion fully bright deposit as demanded by customers; and such processes are easy to chemically control and have a broad range of concentrations that will
Silveron GT-101 Bright Cyanide-Free Silver Silver
The product can be used in conventional plating equipment and high speed reel-to-reel jet or wire plating equipment. The silver deposits can be applied to both copper and nickel alloy substrates. Cyanide-free electrolyte pH 9-10; Chemically stable solution; White bright silver deposit over a broad CD range 0.5 - 15 ASD Cathode efficiency
Electrodeposition of Silver-Cobalt Coatings. Electrolytes.
Non-cyanide or without free cyanide electrolytes for silver deposition. Type of electrolyte References Electrolyte composition Concentration g dm-3 J A dm-2 T C Note Ferrocyanide 6 AgCl K 4 Fe CN 6 K 2CO 3 СО NH 2 2 20–40 160–200 20 1–1.5 60–80 Soluble anodes can not be used because of the silver passivation in this
ARGUNA 630 GAM Hard Silver Electrolyte Electroplating
For the deposition of silver layers with high hardness ARGUNA 630 GAM is an alkaline cyanide hard silver electrolyte for electro technical appli ions. The additives increase the wear resistance compared to conventional silver layers significantly: The layers obtain a stable hardness of 120 to 130 HV even after thermal aging.
AURUNA 570 Gold Silver Electrolyte Electroplating
Alkaline-cyanide gold alloy electrolyte – gold-saving. AURUNA 570 is an alkaline-cyanide alloy electrolyte for depositing green-yellow gold coatings. The gold-silver alloy has a fineness of approx. 18 carats. The coatings are gold-saving they are bright even as thick layers.
Silveron GT-820 Cyanide-Free Silver Tin Silver Tin
The product can be used in conventional plating equipment at low speed and high speed. The silver-tin alloy can be applied to both nickel and copper or copper alloys. The electroplated silver-tin alloy contains 19-23 % of tin the remaining fraction is silver. Cyanide-free electrolyte; Replacement for Tin for whisker control on press fit connectors
Gold and Silver Plating Basics Products Finishing
Some brightener systems particularly selenium or sulfur-based are more effective in sodium-based solutions. Free cyanide in a silver bath performs several functions. It solubilizes the silver functions as the electrolyte and corrodes the anodes.
Cyanide-free silver electroplating process in thiosulfate
Cyanide-based silver-plating solutions are widely used in electroplating industry because they offer most consistent deposition quality at the lowest cost. Due to environmental concerns cyanide-based process must be replaced with the cyanide-free silver-plating solution 12 . There are multiple studies of cyanide-free silver electroplating
