NON-CYANIDE BRASS PLATING BATH
Can you recommend a cyanide free brass plating bath replacement?
NICKEL ON BRASS AND POROSITY
We are looking for a test that will allow us to determine the porosity of the nickel layer on the brass substrate. Can you give us some direction?
“GROWING” COPPER PLATING BATH
Our cyanide copper strike bath builds up copper metal over a period of time. What causes this, and how can we prevent it?
CORROSION TESTS AND GOLD JEWELRY
Recently we decided that we must do some testing to verify how well our jewelry “holds up” in a corrosive environment (humid environments, perspiration contact, etc.). Do you have any suggestions for us?
Troubleshooting Alkaline Zinc Plating Bath
Can you help us figure out why our alkaline zinc plating bath makes the anodes polarize when the current is on?
IRON IN CHROME TANK
I have a problem with iron in my bath. How would you suggest that I remove the iron?
PLATING ON LEADED STEEL
One type of steel, 12L14, a leaded steel, continually gives us problems with blisters and peeling. Do you have any suggestions as to how we can solve this ongoing problem?
ZINC ON ZINC DIE CASTINGS
We plated a large number of zinc diecasts with zinc and a few months after the plating the parts changed to a bluish color. What is going on?
MIGRATIONS
What do you recommend as a minimum thickness for the copper intermediate layer?
SMALL-SCALE PLATING LINE
I am a hobbyist who wants to set up a small scale plating for copper and nickel. I’m thinking in terms of one- or two-gallon tanks. Can you give me details on how to go about doing this?
BORIC ACID AND MANNITOL
I am required to determine the boric acid concentration in our nickel sulfamate plating bath. Can you provide a procedure for doing this?
WOOD’S NICKEL STRIKE
What happens when “tramp” metals such as copper, lead and chromium build up in a Wood’s nickel strike bath? Can this be a cause of roughness in the subsequent plating step?
