NAME Sistemas de determinación de propiedades mecánicas y microestructura mediante medida no destructiva de propiedades magnéticas

DESCRIPTION

Sistema de medida de propiedades magnéticas que permite obtener información de manera indirecta de las características microestructurales o mecánicas de piezas ferromagnéticas. Sistema de control de ensayo no destructivo útil para obtener información de la microestructura y las propiedades mecánicas de los aceros o detectar los defectos de producción como pueden ser las variaciones de dureza superficial, las quemas de rectificado, las tensiones residuales o la capa endurecida. Sistema de medida de propiedades magnéticas propio al que se le pueden acoplar distintos sensores comerciales o sensores propios dependiendo de la geometría y las características de la pieza a testear. Este sistema se puede utilizar para la realización de medidas manuales o medidas automáticas mediante el empleo de un robot gracias a distintos acoplamientos desarrollados.
