Abstract
La formacion de imperfecciones y ampollas, durante el recubrimiento de autodeposito de superficies de metales no ferrosos, particularmente el acero galvanizado y superficies zincíferas similares, se puede reducir grandemente por la exposicion de las superficies a una solucion acuosa, que inhibe las imperfecciones, de fosfonatos, preferiblemente desde un ácido aminofosfonico, antes del recubrimiento de autodeposito.
