Abstract

UN PAR DE MIEMBROS DE CIERRE HERMETICO DE MATERIAL DURO QUE TIENEN BAJO COEFICIENTE DE FRICCION. UN PAR DE MIEMBROS DE CIERRE HERMETICO DE MATERIAL DURO, TAL COMO UN PAR DE PEQUEÑAS CHAPAS QUE CONTROLAN EL FLUJO DE FLUIDO A TRAVES DE UN GRIFO. EL PRIMER MIEMBRO DE CIERRE HERMETICO ES DE CARBURO DE SILICIO, FORMADO PREFERIBLEMENTE MEDIANTE UN PROCESO DE SILICIACION DE UNA FORMA CARBONOSA SEMIACABADA. EL SEGUNDO MIEMBRO DE CIERRE HERMETICO ES DE UN MATERIAL, AL MENOS, MODERADAMENTE DURO, CAPAZ DE RECIBIR UN ACABADO EXACTO, Y ESTA CUBIERTO CON UNA FINA CAPA DE MATERIAL MAS DURO -CARBURO DE SILICIO U OTRO CARBURO, UN NITRURO O CARBONO CON UNA ESTRUCTURA DE RED CRISTALOGRAFICA CUBICA- APLICADO POR DEPOSICION FISICA O QUIMICA POR VAPOR. ESTA CONFIGURACION DA LUGAR A UN BAJO COEFICIENTE DE FRICCION INCLUSO EN AUSENCIA DE LUBRICACION, IMPIDE LA ADHERENCIA EXCESIVA ENTRE LAS PARTES CON SUPERFICIES ALTAMENTE PULIDAS, GARANTIZA EL FUNCIONAMIENTO SUAVE DURANTE LARGOS PERIODOS DE TIEMPO AUN CUANDO LOS MIEMBROS DE CIERRE HERMETICO SE SOMETAN A ALTAS TEMPERATURAS, Y SE EVITE UNA CANTIDAD EXCESIVA DE FRICCION EN LA SEPARACION INICIAL.
