Hard silver plating
Tip: Readers want to learn from Your Situation 🙂
(little can be learned from abstract questions, so many readers skip them)
Q. Can we have a clean silver plating plant without acid?
Hard silver with antitarnish that is conductive?

A. Hi Vinay
The "clean plant" and "without acid" are slightly related, of course, but actually two different questions.
A clean plant relies more on design and attention to detail than on the specific plating chemistry. My article from back in the '90s, "Plating Shops for the New Millennium" will tell you how to design and run a clean plating shop.
Operating a silver plating plant without acid is probably possible but so impractical that you won't be able to compete. And if by "acid" you actually mean any dangerous materials the answer is no.
A flash of rhodium plating is often used as a conductive anti-tarnish on silver plating, and it will be harder than the hard silver.
Please tell us the details of your situation rather than posing an abstract question.
Luck & Regards,

Q. Hi,
My question is this. I have started a new unit in Oman, but in small level; first of all I want to expand it, and secondly I want a expert for this work. Actually here we have backward type work machinery and other equipment but there is lot of work in Oman for metal finishing . My budget is low for this work but I want to compete in Oman. Give me some suggestions and tricks. Now I have only nickel, silver, gold, copper, brass solution. this is the main in metal finishing. I want information about galvanizing, anodizing, and and many more but later. Now I want the know-how to do long life silver plating on metal and what is the best procedure for hard silver. Which chemicals are used for hard silver.
THANX,

A. Silver plating chemical with Antimony as brightener is harder than normal silver plate.

A. dear ali
annealed silver hardness is 27 kp/mm
additive-free bath has hardness 80-90 kp/mm
bright deposit reach to 130 kp/mm.
for hard deposit look for patent JP55002745. FOR YOUR OTHER ASSISTANCE CONTACT US THROUGH FINISHING.COM.

Hi Ali, yes I agree with you; the plating plant, especially a person who owns a jobshop is dirty (acid fumes, wet area) also the machinery are not updated, this type of electroplating environment is same around the whole globe. You need to use a metallic brightener for silver so that it gives you a good hardness and required brightness, then a very good anti-tarnish dip (chemiabsorption type) will help you a lot.

A. The best way for hard silver electroforming brightener and additives is selenium and potassium antimony tartrate.

Q. I am writing a novel in which I have a character who wears a rattlesnake belt with the fangs covered in silver. These fangs function as the clasps, with two holes punched along the belt portion for the fangs to pierce. - San Antonio, Texas, USA December 29, 2010 A. Hi, Martha  Ted Mooney, P.E.
