Industrial Application Field The present invention relates to a titanium carbonitride ceramic material, more specifically, a titanium carbonitride ceramic material, which has high density, high hardness, and high strength, and is suitable for cutting tool materials and wear-resistant machine parts materials. This invention relates to a new titanium carbonitride ceramic material that exhibits transverse rupture strength. Conventional technology Until now, tungsten carbide has been mainly used as a material for cutting tools, but due to the recent trend of raw material shortages, alternative materials such as sintered titanium carbonitride and diboride Titanium sintered bodies are beginning to attract attention. By the way, titanium carbonitride TiCN exists as a solid solution of TiN and TiC, and the ratio of carbon and nitrogen in it can be freely distributed, and it generally has a high melting point, hardness, and toughness, and also has high oxidation resistance. Because of its good properties, it is attracting attention as a material for cutting tools and wear-resistant mechanical parts. However, since the single sintered body of titanium carbonitride has low flexural strength and is brittle, this single sintered body is not suitable for industrial use. However, it has the disadvantage that it cannot be used for the above-mentioned purposes. Problems to be Solved by the Invention The purpose of the present invention is to provide carbonitrided carbonitrides that have high density, high hardness, high strength, and exhibit excellent transverse rupture strength, suitable as materials for cutting tools and wear-resistant mechanical parts. The purpose of the present invention is to provide titanium-based ceramic materials. Means for Solving the Problems The present inventors have already proposed a titanium nitride-metal boride ceramic material as a material suitable for such purposes (Japanese Patent Publication No. 18349/1983), but further research is required. As a result of progressing with the development of titanium carbonitride
It has been discovered that chromium carbide ceramic materials and titanium carbonitride-chromium carbide-metal boride ceramic materials can also be adapted to the above object, and based on this knowledge, the present invention has been completed. That is, the present invention provides (A) at least one titanium carbonitride powder selected from titanium carbonitride having a molar ratio of carbon to nitrogen in the range of 1:9 to 9:1; A titanium carbonitride ceramic material made by sintering a mixed powder to which 1 to 90% by weight of chromium carbide powder is added, and 1 to 90% by weight of component (B) to the above component (A). The basic component is (C)TiB 2 , CrB 2 , TaB 2 ,
MnB 2 , MoB 2 , VB 2 , NbB 2 , HfB 2 , AlB 2 ,
ZrB2 , TiB, CrB, TaB, MnB, MoB, VB,
Carbon made by sintering a mixed powder to which at least one metal boride powder selected from NbB, HfB, ZrB, W 2 B 5 and Mo 2 B 5 is added in an amount less than 95% by weight based on the total amount. The present invention provides a titanium nitride ceramic material. As the titanium carbonitride of component (A) which is the main component of the present invention, one in which the molar ratio of carbon to nitrogen is in the range of 1:9 to 9:1 is used. If it deviates from this, it will not be possible to obtain a ceramic material with excellent toughness. This titanium carbonitride may be used alone or in a mixture of two or more. In addition, the average particle size of the titanium carbonitride powder is preferably 2 μm or less, more preferably
It is 1 μm or less. The chromium carbide used as component (B) in the present invention includes compounds such as Cr 3 C 2 , Cr 4 C, and Cr 7 C 3 , and these may be used alone or in combination of two or more. It's okay. The average particle size of this chromium carbide powder is preferably 2 μm or less, more preferably 1 μm or less. In the present invention, the amount of the chromium carbide powder added is selected within the range of 1 to 90% by weight based on the total amount of the mixed powder. If this amount is less than 1% by weight or more than 90% by weight, a ceramic material with desired physical properties cannot be obtained. In addition, in the present invention, in order to further improve the physical properties of the ceramic material, the above-mentioned (A) component and (B) are combined.
Furthermore, as the (C) component, TiB 2 , CrB 2 , TaB 2 , MnB 2 , MoB 2 ,
VB 2 , NbB 2 , HfB 2 , AlB 2 , ZrB 2 metal diboride, TiB, CrB, TaB, MnB, MoB, VB,
NbB, HfB, ZrB metal monoboride and W 2 B 5 ,
A metal boride powder selected from among the metal pentaborides of Mo 2 B 5 can be added. These metal boride powders may be used alone or in combination of two or more, and those having an average particle size of 2 μm or less, preferably 1 μm or less are desirable. The metal boride powder is used in an amount of less than 95% by weight based on the total amount of the mixed powder. Especially the amount
In the range of 20 to 70% by weight, excellent ceramic materials with high strength, density and hardness are obtained. The ceramic material of the present invention can be produced by mixing the above-mentioned components and using a method similar to that used for conventionally known ceramic materials. For example, by filling a mold with a raw material powder mixture,
Cold compressed using a press pressure of about 0.5 to 10 ton/ cm2 , then further compressed by a rubber press to 0.5 to 100 ton/cm2.
Molding is done using hydrostatic pressure of about 10ton/cm2. Of course, it may be molded using either one, or may be molded by a slurry method. Next, the green compact obtained in this way is placed in a vacuum or in a non-oxidizing atmosphere such as argon or hydrogen at a temperature of 1400 to 2000°C for 30 to 30 minutes.
Sinter for 300 minutes. Furthermore, if necessary, hot isostatic sintering can be used to produce 2 tons/2 tons using argon gas, etc.
5~1300~1900℃ under pressure below cm2
Sinter for 300 minutes. According to another method, after filling a mold such as a graphite mold with a raw material powder mixture, the mixture is placed in vacuum or in a non-oxidizing atmosphere such as argon or hydrogen at a die pressure of 50 to 300 Kg/cm 2 and a temperature of 1300 to 1,300 kg/cm 2 . 2000℃
It can be sintered using the so-called hot press method, which involves heating and sintering for 10 to 200 minutes under the following conditions. In this way, a ceramic material suitable for cutting tools and the like is obtained. Effects of the Invention According to the present invention, a titanium carbonitride material having high density, high hardness, and high strength suitable for a cutting tool can be obtained. Furthermore, when the material of the present invention is used in the atmosphere at a temperature of 600° C. or higher, Cr 2 O 3 is generated and the coefficient of friction is reduced, so it is useful as a high-temperature sliding material. EXAMPLES Next, the present invention will be explained in more detail with reference to Examples. Example 1 Cr 3 C 2 powder is added to Ti (C 0.5 N 0.5 ) powder in various proportions to make a mixed powder, which is then made into a green compact using a mold and further pressed using a rubber press.
Densify at a pressure of 3ton/ cm2 . The green compact thus obtained was heated and sintered at 1850° C. for 90 minutes in a vacuum. The obtained ceramic material had high density, transverse rupture strength, and hardness. The results are shown in Table 1. For comparison, the results obtained without adding Cr 3 C 2 powder are also shown.
