Abstract

Kompozyt zawiera fazę ceramiczną w postaci tlenku glinu w odmianie α-Al2O3 o wielkości ziarna od 0,3 - 0,6 μm w ilości od 5% masy do 15% masy, przy czym faza proszku węglika wolframu i kobaltu WC-Co o wielkości ziarna od 1,5 μm do 5,00 μm stanowi od 85% do 95% masy, przy zawartości kobaltu Co w ilości 10% masy. Sposób wytwarzania kompozytu polega na tym, że do mieszaniny wyjściowej zawierającej od 85% do 95% masy proszku węglika spiekanego typu WC-Co o zawartości kobaltu w ilości około 10% masy, dodaje się proszek tlenku glinu Al2O3 w ilości od 5% masy do 15% masy, przy czym średnia wielkość ziarna proszku WC-Co wynosi od 1,5 do 5,0 μm, a wielkość proszku α-Al2O3 mieści się w przedziale od 0,3 do 0,6 μm, po wstępnym sprasowaniu wypraski poddaje się procesowi spiekania przy temperaturze od 1250°C do 1450°C i ciśnieniu od 1 MPa do 100 MPa.The composite contains a ceramic phase in the form of alumina in the α-Al2O3 variety with a grain size of 0.3 - 0.6 μm in an amount of 5% to 15% by mass, wherein the tungsten carbide and cobalt powder phase WC-Co with a grain size of 1.5 μm to 5.00 μm constitutes 85% to 95% by mass, with the cobalt content Co in an amount of 10% by mass. The method of producing the composite consists in adding Al2O3 aluminum oxide powder in an amount of 5% to 15% by weight to the initial mixture containing from 85% to 95% by weight of WC-Co type sintered carbide powder with a cobalt content of about 10% by weight, wherein the average grain size of the WC-Co powder is from 1.5 to 5.0 μm, and the size of the α-Al2O3 powder is in the range of 0.3 to 0.6 μm, after pre-compressing the compact, it is subjected to a sintering process at a temperature of 1250°C to 1450°C and a pressure of 1 MPa to 100 MPa.
