... Abstract Selective plating, also known as brush plating, differs from traditional tank or bath plating in that the workpiece is not immersed in a plating solution (electrolyte). Instead, the electrolyte is brought to the part and applied by a handheld anode or stylus, which incorporates an...

... reduction of the metal ion to the metal to be deposited on the metal substrate. Chemical deposition can also be accomplished by galvanic reaction between a less noble metal and a more noble metal ion. The noble metal is deposited via this reaction. This form of the process is known as immersion plating...
