Abstract

SE PRESENTAN PARTICULAS ABRASIVAS Y ARTICULOS HECHOS A PARTIR DE ELLAS EN DONDE LAS PARTICULAS COMPRENDEN GRANULOS FINOS DE NITRURO DE BORO O DE DIAMANTE CON FORMAS PARTICULARES AGLUTINADOS MEDIANTE UNA MATRIZ SINTERIZADA DE UNA O MAS CAPAS DE MATERIAL DE REVESTIMIENTO ACTIVO QUE ESTA QUIMICAMENTE FIJADO A LA SUPERFICIE SUBYACENTE. ESTAS PARTICULAS SE OBTIENEN A BASE DE SINTERIZAR LOS GRANULOS REVESTIDOS BAJO CONDICIONES RELATIVAMENTE SUAVES EN COMPARACION A LAS NECESARIAS PARA FORMAR PARTICULAS ABRASIVAS MONOCRISTALINAS DE TAMAÑO SIMILAR. EN ALGUNAS PUESTAS EN PRACTICA DE LA INVENCION, SE PUEDE PRESCINDIR DEL USO DE UN EQUIPO DE ALTA PRESION Y DE ALTA TEMPERATURA. LAS PARTICULAS PRESENTAN UNAS CARACTERISTICAS DE RUPTURA MEJORADAS QUE SE PUEDEN CONTROLAR SELECCIONANDO EL GROSOR DEL REVESTIMIENTO, EL TIPO DE REVESTIMIENTO Y EL TAMAÑO DE LOS GRANULOS FINOS A AGLUTINAR. EL PROCESO ES MUY ADECUADO PARA EL USO DE UN POLVO DE DIAMANTE PRODUCIDO A PARTIR DE PROCESOS DE DEPOSICION DE VAPOR QUIMICO.
