Problems solved by technology

Tungsten carbide has relatively good properties in terms of hardness, toughness, and flexural strength. However, due to the high density of tungsten itself, the density of tungsten carbide materials has always been an important obstacle that limits its application.
Moreover, the resources of tungsten are limited and the price is relatively high. Using a large amount of tungsten carbide will make the cost of the product higher, which is not conducive to market competition and resource conservation.

Embodiment Construction

[0010] A cermet material of the present invention, the ceramic metal material is composed of the following components: 60-90 parts of TiC, 0-10 parts of WC, 0-5 parts of NbC, 0-5 parts of Cr 3 C 2 , 5~25 parts of Fe, 1~10 parts of Ni, 0.5~5 parts of Co, 0.5~5 parts of Cu, 0.5~5 parts of Mn, 0.5~5 parts of Cr, 0~5 parts of Mo and 0~10 parts of TiN. This cermet material utilizes the low density of TiC (only 31.6% of WC) and low cost (unit price is only about 20% of WC), which greatly reduces the application cost of cemented carbide and saves tungsten resources; TiC grains have excellent The excellent self-lubrication and low friction coefficient make TiC-based cemented carbide have the outstanding advantages of anti-adhesion, so that it can be successfully applied in metal forming and other fields; adding Cr can greatly improve the corrosion resistance and heat resistance of the alloy; Adding Mo and WC can improve the wettability of the bond relative to TiC, thereby increasing ...

Abstract

The invention discloses a cermet material, which is prepared from the following components in parts by weight: 60-90 parts of TiC, 0-10 parts of WC, 0-5 parts of NbC, 0-5 parts of Cr3C2, 5-25 parts of Fe, 1-10 parts of Ni, 0.5-5 parts of Co, 0.5-5 parts of Cu, 0.5-5 parts of Mn, 0.5-5 parts of Cr, 0-5 parts of Mo and 0-10 parts of TiN. According to the cermet material, low density (just 31.6% of WC) and low cost (just about 20% of WC in unit price) of TiC are utilized, so that the application cost of hard alloy is greatly reduced, and a tungsten resource is also saved.

Description

technical field [0001] The invention relates to a cermet material. Background technique [0002] At present, the commonly used cermet materials are mainly concentrated on tungsten carbide, and its main component is composed of tungsten carbide and certain binder phase metals (nickel, molybdenum, etc.). Tungsten carbide has relatively good properties in terms of hardness, toughness, and flexural strength. However, due to the high density of tungsten itself, the density of tungsten carbide materials has always been an important obstacle that limits its application. Moreover, the resources of tungsten are limited and the price is relatively high. The use of a large number of tungsten carbide will make the cost of the product higher, which is not conducive to market competition and resource conservation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cermet material that can greatly reduce the use of tungsten car...
