Abstract

Procedimiento para el recubrimiento de unos cuerpos huecos, en el cual es preparada una mezcla de polvos a partir de un polvo dispensador de metal, de un polvo de relleno inerte y de un polvo activador consistente en un halogenuro metálico; esta mezcla de polvos es puesta en contacto con la superficie interior del cuerpo hueco, la cual ha de ser recubierta, y la mezcla es calentada; procedimiento éste que está caracterizado porque el polvo de relleno inerte es preparado con un tamaño medio de las partículas, el cual es más o menos de la misma magnitud como el tamaño medio de las partículas del polvo dispensador de metal; caracterizado porque el polvo dispensador de metal y el polvo de relleno inerte son preparados con un tamaño medio de sus partículas, el cual es mayor de 40 micra; así como caracterizado porque es preparada una mezcla de polvos, con una parte proporcional del polvo dispensador de metal de un 10 hasta un 25 % del peso.
