Abstract
Kompozyt na osnowie węglika spiekanego ze spiekanym węglikiem wolframu WC i metaliczną fazą wiążącą w postaci kobaltu Co, zawiera fazę ceramiczną wybraną z grupy faz MAX, stanowiącą potrójny warstwowy heksagonalny węglik, o ogólnym wzorze Mn+1AXn, w którym n=1 do 3, M oznacza metal przejściowy, A jest elementem z III grupy metali, X oznacza węgiel zaś warstwy węglików metali przejściowych Mn+1Xn są ułożone na przemian z warstwami czystych składników z grupy A, wymieniona faza MAX stanowi od 5% do 15% masy kompozytu, przy czym potrójną fazę ceramiczną stanowi proszek Ti3SiC2 o wielkości ziarna od 3,0 do 5,0 µm w ilości od 5% do 15% masy, zaś faza proszku z węglika spiekanego o wielkości ziarna od 3,0 µm do 5,00 µm stanowi od 95% do 85% masy, przy zawartości kobaltu w ilości 11% masy.The cemented carbide matrix with cemented tungsten carbide WC and a metallic binding phase in the form of cobalt Co, contains a ceramic phase selected from the MAX phase group, consisting of a triple layered hexagonal carbide, with the general formula Mn + 1AXn, in which n = 1 to 3, M means transition metal, A is an element from Group III of metals, X means carbon, and layers of Mn + 1Xn transition metal carbides are alternated with layers of pure components from Group A, said MAX phase constitutes from 5% to 15% of the mass of the composite, the ceramic triple phase is Ti3SiC2 powder with a grain size from 3.0 to 5.0 µm in an amount of 5% to 15% by weight, while the cemented carbide powder phase with a grain size from 3.0 µm to 5.00 µm is from 95 % to 85% by weight, with 11% cobalt content.
