ABSTRACT:
A method of electric arc spraying metal upon an article. The method comprises providing an article to be sprayed, providing a supply of fusible metal feedstock, providing a metal feedstock feeding device, and providing a substrate of conductive heat resistant material. The substrate has a centrally disposed orifice extending therethrough. A source of electrical current is provided having a first electrode electrically coupled with an end of the metal feedstock, and a second electrode electrically coupled with the plate of conductive material. The source of current is activated to establish an electric arc between the metal feedstock and the plate of conductive material. The electrical arc creates a droplet spray of metal from the metal feedstock. The droplet spray is directed through the orifice in the substrate towards the article. The power supply is periodically pulsed between a first current and a second current.
