Abstract
UN METODO Y APARATO PARA LA DETECCION DE DEFECTOS EXISTENTES EN UN MIEMBRO QUE SE VA A INSPECCIONAR, EN EL QUE LA SUPERFICIE DE ESTE MIEMBRO SE CUBRE CON POLVO DEPOSITADO USANDO, POR EJEMPLO, ELECTRICIDAD ESTATICA ANTES DE DETECTAR EL DEFECTO. LA SUPERFICIE DEL MIEMBRO PUEDE SER CUBIERTA CON POLVO COMPLETAMENTE O EN UN ESPESOR MUY PEQUEÑO DE MANERA QUELA SUPERFICIE QUEDE PARCIALMENTE EXPUESTA. A CONTINUACION SE CALIENTA LA ZONA SUPERFICIAL DEL MIEMBRO MEDIANTE CALENTAMIENTO POR INDUCCION DE ALTA FRECUENCIA Y DESPUES SE MIDE LADISTRIBUCION DE TEMPERATURAS SOBRE LA SUPERFICIE CON UN TERMOMETRO DE RADIACION. LA PARTE PARA LA CUAL LA TEMPERATURAMEDIDA ES DIFERENTE DE LOS ALREDEDORES SE CONSIDERA UN DEFECTO. LA SUPERFICIE DEL MIEMBRO SE CUBRE CON POLVO DEMANERA QUE LA EMISIVIDAD SUPERFICIAL, Y LA DISTRIBUCION DE TEMPERATURAS RESULTANTE MEDIDA CON EL TERMOMETRO DE RADIACION, RESULTAN CASI IGUAL QUE LAS REALES.
