                Qu\u00e9 nos dice la decoloraci\u00f3n<\/h2>\n\n\n\n

                Amarillo (del amarillo paja al dorado):<\/strong>
                Cuando se utiliza arg\u00f3n, las partes amarillas significan una fuga de aire o gas que invita al aire atmosf\u00e9rico a mezclarse con el arg\u00f3n. Cuanto m\u00e1s importante sea la fuga, m\u00e1s oscura ser\u00e1 la coloraci\u00f3n amarilla. Pasado un punto de gravedad de la fuga, las piezas pueden aparecer azules en lugar de amarillas.<\/p>\n\n\n\n

                \n

                Azul (del azul cielo al azul noche):<\/strong>
                Cuando se utiliza arg\u00f3n, las partes azules significan fugas de aire cada vez m\u00e1s graves, fugas de gas o mezcla atmosf\u00e9rica. Cuando se utiliza nitr\u00f3geno, las partes azules significan fugas de aire m\u00e1s peque\u00f1as. Una vez m\u00e1s, cuanto m\u00e1s oscuro es el color, m\u00e1s grave es la fuga. El color azul tambi\u00e9n puede indicar contaminaci\u00f3n por cobre.<\/p>\n<\/div>\n\n\n\n

                <\/div>\n\n\n\n
                \n

                Verde (de verde lima a verde bosque):<\/strong>
                Las partes verdes significan algunos problemas potenciales, incluyendo:
                1. La puerta del horno se dej\u00f3 abierta entre ciclos, o el horno no se mantuvo en vac\u00edo durante un per\u00edodo prolongado
                2. Las piezas se introdujeron en el horno excesivamente h\u00famedas o con aleaciones de soldadura h\u00fameda.
                3. El horno funcionaba a altas temperaturas y en un vac\u00edo intenso, liberando el cromo de las piezas y accesorios.
                4. La zona caliente absorbi\u00f3 vapor de agua
                5. Puede haberse producido una contaminaci\u00f3n por cobre en el proceso
                6. Fugas en la camisa de agua, fugas en el intercambiador de calor, restos de agua, etc.<\/p>\n\n\n\n

                \"Graphite<\/figure>\n<\/div>\n\n\n\n
                <\/div>\n\n\n\n

                Negro (del gris claro al negro total):<\/strong>
                Cuando se utiliza arg\u00f3n, el color negro puede indicar una fuga grave en el sistema. El negro tambi\u00e9n puede indicar contaminaci\u00f3n por carbono en el proceso. Esto puede ocurrir durante la carburaci\u00f3n a presi\u00f3n parcial, o ser el resultado de piezas con holl\u00edn que no se han limpiado completamente antes del procesamiento t\u00e9rmico.<\/p>\n\n\n\n

                *Las capas de contaminaci\u00f3n inferiores a 0,1 \u03bcm son transparentes y el ojo humano no puede distinguir correctamente el color. Los clientes pueden identificar la decoloraci\u00f3n en funci\u00f3n del grosor de la capa de contaminaci\u00f3n en la c\u00e1mara de calentamiento o en la pieza. Los aceros para herramientas son menos sensibles y pueden tratarse t\u00e9rmicamente con un bajo nivel de vac\u00edo. Los aceros inoxidables y las superaleaciones son susceptibles incluso a las m\u00e1s m\u00ednimas trazas de ox\u00edgeno en el sistema de vac\u00edo.<\/p>\n\n\n\n
