Palladium Plating Solution

In a palladium plating solution of the invention containing a soluble palladium salt and an electrically conductive salt having a liquid composition containing germanium the amount of the soluble.

Palladium plating solution. Spc has developed a palladium plating process that reliably provides a high quality coating for various components and products. This product produces a consistent bright white mirror finish that is tarnish resistant. This depends entirely on whether palladium or a palladium alloy is to be deposited on the object. This solution plates quickly and produces stunning results.

Bright palladium solution this platinum group metal solution plates with a premium white color and does not require a rhodium over plate. Wollaston found palladium in crude platinum ore from south america by dissolving the ore in aqua regia neutralizing the solution with sodium hydroxide and precipitating platinum as ammonium chloroplatinate with ammonium chloride. Palladium is harder than most gold deposits is non oxidizing has great resistance to corrosion and has excellent wear resistance properties. Non hazardous shipping complete line of plating solutions cleaners and activators pallabrite mirror is a maintenance free ready to use palladium plating bath purposely designed for flash plating over white metals.

He added mercuric cyanide to form the compound palladium ii cyanide which was heated to extract palladium metal. It is tarnish resistant very durable and nickel free. Hardness the koop hardness of palladium can be as high as 400 as compared with cobalt hardened type 2 gold which has a maximum knoop hardness of 200. Palladium plating and palladium nickel plating offer the best cost reducing alternative to gold plating for selective plating of electrical contacts connectors pins and other interfaces.

If an alloy is to be plated proper portions of palladium and either cobalt or nickel are added to the electrolyte solution. In the case of palladium the ions dissolved in the solution may all be palladium or they may consist of a ratio of palladium and other metals. The present invention provides a palladium plating solution comprising at least 1 to 60 g l in terms of the amount of palladium of a soluble palladium salt and 0 1 to 300 g l of a sulfamic acid. Electrolytes of this type are among the most widely used solutions for palladium electrodeposition.

2 5 grams palladium per liter. They work at a ph value of between 7 5 and 10 and palladium is electrodeposited at 300 to 700 mv as dense bright layers.
