A method for melt-coating a surface
Abstract
A method for coating a surface comprises providing an electrostatically charged powder, irradiating the powder with energy until the powder or the surface melts, and allowing the surface to solidify. Electrostatically charging a powder causes a charge to be placed on the surface of each particle. It is sometimes referred to as ionizing the powder. If sufficient charge is placed on the powder, the effect is to decrease the bulk density of the powder by increasing the separation between some or all the particles. It is the increased separation that improves the absorption of energy by a powder.
