Cañón de electrones pulsado para tratamiento superficial de metales

Abstract

Se ha desarrollado un cañón de electrones de cátodo frío para el tratamiento térmico de superficies metálicas. El canon prove pulsos de electrones altamente monoenergéticos de hasta 120A y de duración entre 10μs y 30μs ajustable entre 15keV y 30keV. La profundidad de la pellcula fundida depende de la penetración de los electrons y de la difusión del calor. En enfriado rápido contra el sustrato da lugara cambios en la microestructura de la superficie. Se presentan resulta dos abrenidos con muestras de acero inoxidable. Se muestra que a pesar de la alta energia del haz de electrones, el área fundida es menor que lo esperado. Se discuten las possibles causas de esta discrepancia. A pulsed glow discharge electron beam has been developed for the thermal treatment of metal surfaces. The gun provides highly monoenergetic electron pulses adjustable between 15Kev and 30Key, of up to 120A, lasting between 10μs and 30μs. The depth of the melted film depends on both the electron penetration and the heat diffusion. The fast cooling against the substrate yields changes in the surface microstructure. Results obtained with stainless steel samples are presented. It is shown that despite the high energy of the electron beam, the melted area results smaller than expected. The possible source of this discrepancy is discussed.
