TLDR
A horno al vacio based on a tubo cilindrico de cuarzo for difundir two or mas capas delgadas metalicas for formar una aleacion was presented in this paper, where the horno trabaja in un ambiente inerte de argon (Ar) and una temperatura controlada a traves of una plancha interior de ceramica.Abstract:
En este trabajo se discute la fabricacion de un horno al vacio basado en un tubo cilindrico de cuarzo para difundir dos o mas capas delgadas metalicas para formar una aleacion. El horno trabaja en un ambiente inerte de argon (Ar) y una temperatura controlada a traves de una plancha interior de ceramica y un sistema de control PID basado en un software desarrollado en LabView 7.0. El area de calentamiento de 10 × 5 cm 2 puede elevar la temperatura hasta 600oC debido a sus tapas circulares que cuentan con un sistema de enfriamiento de agua. El horno es calentado y controlado con una fuente de corriente directa y utiliza un termopar tipo K para monitorear la temperatura con una resolucion de ±0.1oC. Se detallan pruebas realizadas en el horno para obtener la aleaciones nanoestructuradas de AuCu.read more
