Hard silver plating
2003
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,

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 antitarnish dip (chemiabsorption type) will help you a lot.

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 Hi, Martha ![]() Ted Mooney, P.E.
