2. Description of the Related Art Japanese Patent Publication No. 4 (1994) discloses a method of coating a hard coating mainly composed of Ti and Al on the surface of a cemented carbide.
Conventional Ti nitride, carbonitride, etc.
There are many cases in which the effect was confirmed by adding Al to carbides and carbides. However, in these confirmed cases, the hard coating itself is only improved by adding Al to the conventional coating composition to improve the oxidation resistance. Therefore, in the current situation, the surface-coated cemented carbide throw-away insert does not have sufficient film adhesion. Particularly in recent years, there is a tendency to process high hardness steel materials after heat treatment, and when such steel materials are processed using conventional surface coated cemented carbide throwaway inserts containing Ti and Al as the main components, acid resistance is high. The chemical resistance becomes insufficient, and the cutting stress is high, and the film is easily peeled off, so that a sufficient tool life cannot be obtained.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The inventors of the present invention have conducted extensive studies to improve the oxidation resistance and peel resistance of surface-coated cemented carbide throw-away inserts.
The following findings were obtained. When cutting a recent high hardness steel material using a throw-away insert, the insert tip portion is exposed to a high temperature of 700 ° C to 800 ° C. When coated on a conventional cemented carbide throw-away insert containing Ti and Al as the main components, the friction resistance between the steel and the coating is large, and the insert tip portion during cutting is exposed to a higher temperature, and the temperature is from 850 ° C to It reaches up to 900 ° C.
Therefore, in such a surface-coated cemented carbide throw-away insert, the acid resistance of the coating itself is exceeded, and a very porous oxide film such as TiO 2 is formed. Also, at such cutting temperature,
Oxidation of the coating is unavoidable, and even the cemented carbide substrate will be oxidized. As a result, both the coating and the base become fragile, causing chipping and peeling, resulting in an insufficient tool life. Further, during the cutting process, the cutting stress applied to the surface-coated throw-away insert is so high that the film peels off, which also results in an insufficient tool life. As described above, in order to cut a high hardness steel material with a sufficient tool life, improving the oxidation resistance and adhesion of the coating significantly improves the tool life.

First, grain boundary fracture is significantly reduced by the addition of these components. For example, when the additive component is X, when the film is exposed to the high temperature in the atmosphere, the conventional Ti and A
In the case of a film containing 1 as a main component, a very porous oxide film such as TiO 2 was formed, but by adding the additive component X, a dense oxide such as (Ti, X) O 2 was formed. It has been found that a film is formed and the amount of external oxidation diffused into the film is significantly reduced. The reason for limiting the addition amount of this additive component will be described. Whatever the additive component X is, if it is less than 0.03 atomic% with respect to Al, the effect of reducing the grain boundary fracture was not recognized. In addition, the oxide film formed during cutting is also TiO 2.
2 and XO 2 form a very porous oxide film mainly,
The effect aimed by the present inventors was not recognized. Further, when the additive component X is added in an amount of more than 30.0 atomic% with respect to Al, the residual compressive stress of the film is -8.0 to -1.
It was confirmed to be very large at 0.0 GPa, and the adhesiveness with the cemented carbide substrate was significantly deteriorated. Furthermore, the inventors of the present invention invented Ti, Al, and a part of Al in the range of 0.03 atomic% or more and 30.0 atomic% or more with respect to Al.
Among r, Ce, Mo, and Nd, one type or two or more types were replaced. It is recognized that the coefficient of thermal expansion is 1.5 times or more as compared with the nitride, carbonitride and carbide coatings.
The range is limited to lower the high temperature physical properties of the coating.

It has been found that when (111) <I (220) ≦ I (200), the oxidation resistance of the coating and the adhesion between the coating and the cemented carbide substrate can be significantly improved. Ti,
A compound nitride in which Al and a part of Al are replaced by another element,
Among carbonitrides and carbides, a film having a strong orientation on the (111) plane has a very fine columnar crystal structure. Further, the residual stress inside the film is also very large, so that grain boundary fracture occurs. In the film having such fine columnar crystals, oxygen penetrates along the fine cracks generated at the grain boundaries. During the cutting process, the tool itself is exposed to a high temperature of 850 ° C to 900 ° C, so that the diffusion energy of oxygen that has penetrated into the coating is further increased, and the oxidation reaction with the components in the coating is accelerated. Oxidation extends to the hard alloy substrate. Further, in such a film, cracks are likely to propagate into the film due to the impact with the work piece, leading to easy cracking or peeling.

It was also found that the grain boundary fracture is reduced due to the increase in the crystal grain size of the coating, and this phenomenon greatly affects the adhesion and the oxidation resistance. This value is limited to Ib / Ia ≦
When 1.0 and Ib / Ia> 5.0, the film has a strong orientation on the (111) plane having many fine grain boundary fractures, no change in the crystalline state is observed, and the residual stress is -6.0 GPa- −
The value was 8.0 GPa, which was extremely large, and no effect was observed even after cutting, so the range was limited to the above range.

It was found that when the value of a (111) was in the range of 2.0 ≦ Ic / Ia ≦ 40.0, a decrease in the grain boundary destruction of the coating was observed, which had a great influence as described above. The values are limited to Ic / Ia> 2.0, Ic / Ia> 40.
This is because the film with 0 does not show any change in the crystal.
