Title:
CARBIDE-BASED ABRASION RESISTANT COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/049361
Kind Code:
A2
Abstract:
Disclosed is a cermet sintered body having a microstructure comprising: a carbide of two or more metals comprising titanium (Ti), which are selected from metals of groups IVA, VA and VIA in the periodic table, a carbonitride of the metals, or a mixture thereof; and one or more metals selected from the group consisting of Ni, Co and Fe, wherein interfacial bond strength is reinforced by controlling the composition of a rim of a core structure and a bonding phase. According to the present invention, the toughness and abrasion resistance of materials can be remarkably improved and characteristics thereof can be controlled by reinforcing interfacial bond strength in a microstructure of a TiC-based or Ti(C,N)-based cermet.
