Abstract

PROCEDIMIENTO PARA COMPROBAR LA PRESENCIA DE FISURAS DE PIEZAS METALICAS DE MODO NO DESTRUCTIVO. COMPRENDE: A) APLICAR UNA SOLUCION CON UNO O VARIOS COLORANTES QUE NO PRESENTAN NINGUNA EMISION BAJO LUZ ULTRAVIOLETA SOBRE LA SUPERFICIE METALICA A COMPROBAR; B) ELIMINAR LA SOLUCION EN EXCESO DE COLORANTE AL PERCIBIR LA PENETRACION DEL COLORANTE EN LOS DEFECTOS SUPERFICIALES; C) APLICAR UN REVELADOR SOBRE LA SUPERFICIE DE B); Y D) IRRADIAR A LA SUPERFICIE METALICA REVELADA CON LUZ ULTRAVIOLETA CON UNA LONGITUD DE ONDA ENTRE 350 Y 390 MM, PARA ENNEGRECER A LOS DEFECTOS SUPERFICIALES DENTRO DEL RECUBRIMIENTO EMISOR DE LUZ. LOS COLORANTES SE ELIGEN ENTRE COLORANTES ROJOS COMO OIL RED 4379, OIL RED CONC, Y OIL RED TAX; LOS DISOLVENTES PARA COLORANTES SE ELIGEN ENTRE TENSIOACTIVOS NO IONICOS (TERGITOL 15-S-5 Y TERGITOL 15-S-9), ESTERES FTALATO (FTALATO DE DIOCTILO O FTALATO DE DIISODECILO) Y DISOLVENTES OXIGENADOS COMO ALCOHOLES SUPERIORES TRIDECANOL; EL REVELADOR ES UN RECUBRIMIENTO ABSORBENTE RICO EN CONTRASTE A LUZ DIURNA, COMPUESTO A BASE DE TALCO Y ABRILLANTADORES OPTICOS; Y LOS ABRILLANTADORES OPTICOS SE ELIGEN ENTRE BLANCOL WN NEW Y CALCOFLUOR WHITE RWP Y LOS DISOLVENTES PARA ABRILLANTADORES SE ELIGEN ENTRE ISOPROPANOL, ACETONA Y 1,1,1-TRICLOROETANO.
