- Such a third coating has a function of the second layer by laminating the first layer and the second layer in addition to the characteristics described in the first coating and the second coating.
- the adhesion strength with the base material is further improved, and the strength of the film is further improved, especially the film hardness at high temperatures.
- the second layer TiN, TiCN, TiAIN, and the like are particularly preferable.
- the first layer compound include the same compounds as those exemplified for the first film.
- each of the first to third coatings described above is formed by a film forming process capable of forming a compound having high crystallinity and high crystallinity in terms of chemical stability. I like it.

- Each of the coatings preferably has a thickness of 0.05 ⁇ m or more and 20 ⁇ m or less (the total thickness when the coating is formed of a plurality of layers). If it is less than 0.05 m, the wear resistance may not be sufficiently improved, and if it exceeds, the residual stress of the coating itself may increase and the adhesion strength with the substrate may decrease. Therefore, the thickness of such a coating is more preferably 15 ⁇ m at the upper limit, 0.5 m at the lower limit, and more preferably 1 / z m. The thickness of such a coating can be measured, for example, by cutting a surface-coated cutting tool and observing the cross section using a SEM (scanning electron microscope).
- each of the coating films has a cubic crystal structure. This is because the chemical stability at high temperature is excellent.
- the concentration of chlorine in the coating is preferably 0.0001% by mass or more and 1% by mass or less.
- the amount is less than 0. 0001% by mass, the above-mentioned effects caused by the chlorine content may not be sufficiently exhibited. If it exceeds 1% by mass, the hardness of the coating may be deteriorated. Therefore, such chlorine concentration is more preferably The limit is 0.1% by mass, more preferably 0.03% by mass, and the lower limit is 0.001% by mass.
- Such chlorine concentration can be measured by XPS (X-ray electron spectroscopy) method, SIMS (secondary ion mass spectrometer) method, ICP (inductively coupled high-frequency plasma spectroscopy) method or the like.
- the chlorine concentration in the coating layer containing chlorine has a chlorine concentration in the above-described range.
- an arbitrary intermediate layer can be formed between the substrate and the coating.
- Such an intermediate layer usually has a characteristic of improving the wear resistance or improving the adhesion between the base material and the coating, and can be formed as one layer or a plurality of layers.

- a surface-coated cutting tool of the present invention which is a drill, was manufactured by using a drill (JISK10 cemented carbide) having an outer diameter of 8 mm as a base material and forming the coating film shown in Table 3 thereon. Also this and Similarly, as shown in Table 3, a surface-coated cutting tool was manufactured as a comparative example in which a film containing no chlorine was formed.
- a drill JISK10 cemented carbide
- a surface-coated cutting tool of the present invention which is an end mill, was produced by forming a coating film shown in Table 4 on a 6-blade end mill (JISK10 cemented carbide) having an outer diameter of 8 mm as a base material.
- a surface-coated cutting tool as a comparative example in which a film containing no chlorine was formed as shown in Table 4 was produced.
- the side surface of the end mill with respect to SKD11 HRC60
- a surface-coated cutting tool of the present invention which is a cutting tip, was produced by forming the coating shown in Table 5 on the surface of the substrate.
- a surface-coated cutting tool as a comparative example in which a film containing no chlorine was formed as shown in Table 5 was produced.
- the outer circumference of the round bar (HRC62) of SCM415 as the actual work material Cutting was performed.
- the cutting conditions were dry cutting with a cutting speed of 180 mZmin, a feed of 0.0 mm / rev., And a cutting depth of 0.11 mm.
- the initial surface roughness Rz was the surface roughness of the work material after cutting for 1 minute, and the durability of the coating was evaluated by the cutting time required for the surface roughness Rz of the work material to be 3.
- the 10-point average roughness specified in Rzi IS B0601 is shown. The results are shown in Table 5. It is shown that the longer the cutting time required for the surface roughness Rz to be 3, the better the durability.
