Abstract
La presente invención se refiere a un método para aplicar un espesor deseado de un revestimiento suprayacente a la superficie de un componente que tiene una pluralidad de perforaciones pequeñas, espaciadas, en dicha superficie, caracterizado porque comprende los pasos de: (a) disponer en cada perforación un obturador positivo que es volatilizable a una temperatura menor que la temperatura del procedimiento de revestimiento; en donde cada obturador tiene una porción de cabeza que estan agrandada con respecto al diámetro de su agujero respectivo y que topa con la superficie del componente y que se proyecta por encima de la superficie a una distancia mayor que por lo menos el doble del espesor del revestimiento deseado (b) alicar al espesor deseado del revestimiento suprayacente a la superficie de componente, en donde el calor del procedimiento de revestimiento provoca que sólo una porción de la cabeza de cada obturador volatilice, volatilización que interfiere con la deposición del revestimiento sobre cada cabeza de obturador, y en donde la cabeza de cada obturador sobresale por encima de la superficie de revestimiento al completarse el procedimiento del revestimiento y (c) separar completamente los obturadores del componente al completarse el proceso de revestimiento, en donde las perforaciones se abren de esa manera y están sustancialmente libres de revestimiento.
