ABSTRACT:
The present invention provides a method of coating an electrospray emitter with silver and then gold utilizing wet-coating processes. First, the electrospray emitter is immersed in a silver-containing liquid solution to coat the electrospray emitter in a layer of silver. Next, the silver-coated electrospray emitter is removed from the silver solution and rinsed with water. The silver-coated electrospray emitter is then annealed to stabilize the silver layer. Once the silver layer has been stabilized, the silver-coated electrospray emitter is immersed into a gold-containing liquid solution and a voltage is applied. This voltage serves to electrochemically deposit a gold layer onto the silver layer. The gold- and silver-coated electrospray emitter is then removed from the gold-containing liquid solution and rinsed with water and, preferably, with nitric acid.
