Abstract

Fine particulates were removed from a flat surface and cavities by shock/plasma produced by electro-static discharge (ESD). The ESD in air formed by discharging a capacitor between two 1-mm separated pin electrodes. Both irregularly shaped glass and spherical magnesium served as contaminant particulates. The ESD energy and pressure produced by the shock were characterized. Both powders were effectively displaced by the ESD-generated shock and plasma. Displaced particles were de-agglomerated. While glass melted, flammable magnesium powder did not ignite. ESD-generated plasma and shock offer an attractive, inexpensive, and safe alternative to laser shock cleaning methods for removal particulate contaminants from surfaces.
