ある。Conventionally, it has been carried out to extend the service life of a tool part O consisting of a cemented carbide layer and cermet and coat it with a wear-resistant material o1 [K41110] consisting of a cemented carbide and a cermet. Coated tool parts, in which the surface of the base body is coated with wear-resistant material, have superior wear resistance compared to tool parts that consist only of the base body. PV-P is a method for forming a coating layer that is millier than that of the base material.
(physical vapor deposition method) or OV'D (chemical vapor deposition method), it is necessary to raise the temperature69, and during the cooling process, the coating layer is Tensile stress may be applied to the material, causing scratches. %, when a coating layer is formed on the surface of a substrate by the QVDI process, since the coating layer is formed at a high temperature, the rate of heat generation in the coating layer is also high, and even if the thickness adjusted during the cooling process is When a coated tool part 19j with a fragile coating layer is used as a cutting tool, cutting stress is applied to the tip of the coated tool part.
There is a problem in that two cracks occur in the coating layer, and these cracks propagate inside the base body, leading to damage to the tool parts.

−mb返すことによって判明した。The ninth type of kO has been proposed to improve the wear resistance, plastic deformation resistance, and chipping resistance of coated tool parts, and the present inventors have also added a highly wear-resistant material to the coating layer of coated tool parts. We propose coated tool parts with improved wear resistance, plastic deformation resistance, and chipping resistance (by optimally combining the properties of hard materials and lubricity materials). However, tests have shown that the coating layers of these coated tool parts also have different wear resistance, layer resistance, deformation resistance, and fracture resistance depending on the relationship with the structure of the substrate surface layer of the cemented carbide and cermet that are coated. t

As a result, the coated tool part has improved wear resistance, plastic deformation resistance, and chipping resistance due to the combined strength of the coating layer and the base surface layer.

When using a coated tool, the outer coating layer, which is the outermost layer of the coated tool part, is a hard phase made of a high-hardness material, so it has excellent resistance to scratch-like wear (abrasive wear) caused by chips generated during cutting. The high hardness material of the outer layer of the coating contributes to the wear resistance against crater wear on the rake face of tool parts at the initial wear stage, and as the crater wear progresses, the inner layer of the coating contributes to the wear resistance. Metal sulfide, which is a lubricating material contained in the composite phase of the process, appears little by little on the crater surface and acts as a lubricant on the contact surface between the chips and the tool parts.
Together with the outer coating layer, it contributes to wear resistance. In addition, wear resistance is improved due to the lubricating effect of sulfide, and the plastic deformation resistance of the base material is also improved because temperature increases are less likely to occur on the surfaces of tool parts and the surfaces of tool parts that come into contact with bamboo chips. effective. Regarding the metal sulfides used in ζ\, group 6a metal sulfides are superior when focusing on lubricity, but when considering adhesion and wettability with the hard phase of the substrate and outer coating layer, In particular, a metal sulfide consisting of an element contained in the hard phase and the substrate is suitable, and a titanium sulfide is optimal if the hard phase and the substrate contain a titanium compound.

濡れ性に効果があるためでおる。The reason why the inner coating layer of the coated tool part of the present invention is made of a composite phase is because
This is because it has an effect on the strength of the inner coating layer itself and on the adhesion and wettability between the substrate and the inner coating layer.

There is a structure in which a mixed phase of metal sulfide is coated, and a structure in which the former and the latter Oa are combined, that is, after a hard phase is coated parallel to the substrate surface, this hard phase O surface mK high rigidity material and metal Oa are coated.

の靭性が向上し耐欠損性が優れたものである。In the base of the coated tool part of the present invention, the base surface layer from the base surface to a depth of 2 to 40 μm toward the inside of the base has a higher content of a binder phase made of metal than the inside of the base.
Therefore, when a crack occurs in the fragile coating layer consisting of the inner layer and the outer coating layer, it is effective to prevent the crack from propagating and progressing inside the base, and this improves the toughness of the coated tool part. It has excellent fracture resistance.

削条件になると基体の先端部に塑性変形が生じてくる。When the coating layer of the coated tool part of the present invention contains a lubricating material, the temperature rise at the part where the chips and the tool part come into contact is small, and this is effective in improving the plastic deformation resistance of the base.
When the cutting conditions are such that the heat rises even higher, such as ll & half-cut cutting and flat-feed cutting, plastic deformation occurs at the tip of the base.

た耐重性変形性を持つ被覆工具部品になる。However, there are also methods to reduce the binder phase content of the substrate.
A method of increasing the carbide or nitride content of group 1 and 5a metals also promotes embrittlement of the entire substrate, leading to defects in the substrate. Therefore, it is necessary to increase the amount of the binder phase only in the surface layer of the substrate, like the substrate in the coated tool parts of the present invention.
Therefore, the coated tool parts have excellent toughness and are useful for improving tool life.Furthermore, when the coated tool parts are precipitated on the hard phase, which is a high hardness material, in the base surface layer with a large amount of binder phase, it not only has toughness but also has even better weight resistance and deformability.

If the depth exceeds m1, plastic deformation occurs and the life of the tool parts is shortened, so the base surface layer #i was set to 2 to 40 μm.
