Abstract

A találmány tárgya kompozit anyag, ami keményfém- vagycermethordozótestből áll, amely legalább egy gyémántréteggel vanbevonva. A találmány szerinti kompozit anyagnál, a keményfém- vagycermethordozótest C-tartalma, a maximálisan lehetséges tartalom 89%-aés 99%-a, előnyös módon 94%-a és 99%-a közötti értéket tesz ki,amelynél még nem lép fel C-porozitás, vagy keményfém-hordozótestnélCo-kötéssel, a mágneses telítési polarizáció, a maximális telítésipolarizáció 4psmax = 2 Co-2,2 Cr3C2 értékének, 89-99%-t, előnyösen 94-99%-t teszi ki. A találmány tárgya eljárás a kompozit anyagelőállításához, amelynél a porszerű kiindulási anyagot megőrölik,granulálják, formatestbe préselik, és a formatestet utána zsugorítják,az előállított zsugorított testet adott esetben utókezelik ésvégezetül bevonják. A találmány szerinti eljárásnál, a formatestet afelhevítési fázisban 800- 1100°C közötti hőmérsékletnél, előnyösen900°C-nál, H2 atmoszférában 1 térfogatszázalékig terjedő CH4-el, 1 barnyomás alatt, vagy Ar- atmoszférában 0,1 térfogatszázaléknál kisebbCH4-el, 1 bar-nál nagyobb nyomáson hőkezelik, hogy a kívánt C-tartalmat be tudják állítani.
