Abstract
LA PATENTE AFECTA A UN PROCESO DE PRODUCCION DE CAPAS DE MATERIAL DURO CVD O PVD, COMO PROTECCION ANTIDESGASTE SOBRE PIEZAS DE METAL DURO CON WC - CO O WC -NI, SOBRE TODO, ELEMENTOS CORTANTES, EN LOS QUE AL MENOS UNA DE LAS CAPAS ES METAL BORONITRURO. SEGUN LA PATENTE, SE MANTIENE LA CONCENTRACION DE BORO EN LA CAPA METAL - BORONITRURO POR DEBAJO DEL VALOR LIMITE, EN EL QUE JUNTO A LA FASE DE CRISTAL DE MEZCLA BORONITRURO APARECE EN PRINCIPIO UNA FASE DIBORURO. AL APLICAR UNA CAPA INTERMEDIA SIN BORO (O CON UNA CANTIDAD INAPRECIABLE) COMO BARRERA DE DIFUSION ENTRE METAL DURO Y LA CAPA METAL BORONITRURO SE IMPIDE LA FORMACION DE FASES WCOB O WNIB EN LOS MARGENES DEL METAL DURO DE FORMA QUE NO SE PERJUDICA LA TENACIDAD DEL METAL DURO. LA CAPA METAL - BORONITRURO SE LLEVA A CABO PREFERENTEMENTE CONO UNA CAPA DE TITANIOBORONITRURO CON UNA CONCENTRACION DE BORO ENTRE 1.5 Y 15% DE ATOMOS O COMO CAPA DE CIRCONIOBORONITRURO CON UNA CONCENTRACION DE BORO ENTRE 0.1 Y 2% ATOMOS. SE PUEDE APLICAR ENUNA SOLA CAPA O EN MAS CAPAS, ALTERNANDOSE CON OTRAS CAPAS DE MATERIAL DURO. COMO CAPA INTERMEDIA HA PROBADO SU EFICACIA UNA CAPA SIMPLE O VARIAS CAPAS DE UN CARBURO, NITRURO O CARBONITRURO DE LOS ELEMENTOS TI, ZR Y HF.
