Abstract

Se describe en la presente un método y aparato para remoción de óxidos de metal sobre una superficie de un componente por la vía de la unión de electrón. En una modalidad, se proporciona un aparato de emisión de campo, en donde los electrones se unen a por lo menos una porción del gas de reducción para formar iones atómicos negativamente cargados que remueven los óxidos de metal, que comprende: un cátodo que comprende una parte eléctricamente conductora y que comprende por lo menos una o más protuberancias que tienen una alta curvatura de superficie, en donde el cátodo es circundado por un material dieléctrico que luego es circundado por un ánodo eléctricamente conductor, en donde el cátodo y el ánodo son cada uno conectados a una fuente de voltaje eléctrico, y el material dieléctrico entre el cátodo y el ánodo se polariza para proporcionar un campo eléctrico en una o más protuberancias y de esta manera electrones desde el cátodo.
