How Gold Electroplating Is Done - Sharretts Plating Company

Modern gold plating, called gold electroplating, relies on a chemical process to combine various layers of metal into a solid piece with a layer of gold resting on the surface. Electroplating has been in use commercially since the 1840s and was heavily refined during the two World Wars.

How Gold Plating is Done, Step by Step - Analyzing Metals

Gold plating is an easy technique, but before beginning the process, make sure your plater follows the best practices for best plating results. Step 1: Surface Preparation The surface of the metal to be plated must be very clean, so oils or dirt must be removed, and the piece must be polished.

Gold plating - Wikipedia

Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver to make silver-gilt , by chemical or electrochemical plating. This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects, see gilding .
