Abstract

LA PRESENTE INVENCION SE REFIERE A LA REALIZACION DE PLACAS ANTIABRASION. LA SUPERFICIE ANTIABRASION DE LA PLACA ESTA CONSTITUIDA POR LA CARA EXTERNA (5) DE UNA CAPA DE MATERIAL COMPUESTO A BASE DE GRANOS DE CARBURO DE TUNGSTENO FUNDIDO ESFERICO, LIGADOS EN UNA ALEACION DE SOLDADURA. LA SUPERFICIE (5) DE TRITURACION PRESENTA UN ESTADO DE SUPERFICIE LISA Y REGULAR DE MOLDEADO. LA CAPA ANTIABRASION CONTIENE UNA DISTRIBUCION DESORDENADA COMPACTA, REGULAR Y SENSIBLEMENTE HOMOGENEA DE GRANOS DE CARBURO DE TUNGSTENO. LA SUPERFICIE (5) SE REALIZA POR MOLDEADO: LOS GRANOS DE CARBURO DE TUNGSTENO ESTAN INSERTADOS ENTRE LAS PAREDES DEL MOLDE Y EL NUCLEO (2) DE LA PIEZA, Y SE PROVOCA, POR ELEVACION DE TEMPERATURA, UNA INFILTRACION DE ALEACION DE SOLDADURA ENTRE LOS GRANOS DE POLVO, EL NUCLEO (2) Y EL MOLDE. LA INVENCION PERMITE AUMENTAR SENSIBLEMENTE LA RESISTENCIA A LA ABRASION DE LAS PLACAS DE TRITURACION.
