になることから、短かい使用寿命しか示さないのか現状
である。However, as cutting speeds and labor savings have increased in recent years, heavy-duty cutting such as high-speed cutting, high feed rate, and cylindrical cutting are becoming necessary. Because the adhesion strength of the coating layer is not fully satisfactory, when this is used under harsh conditions such as high-speed cutting or heavy cutting, the coating layer will peel off, and this peeling will significantly accelerate wear. Therefore, the current situation is that it only has a short service life.

知見を得たのである。Therefore, the wood inventors focused on the conventional surface-coated cermet cutting tools mentioned above from the above-mentioned point of view, and conducted research to improve the adhesion strength of the coating layer to the base surface. The average layer thickness is 0.
When this is made relatively thin to 1 to 15 μm and subjected to ion implantation treatment to allow the ion implantation component to permeate through the coating layer and into the surface of the substrate, the coating layer will adhere to the surface of the substrate. Not only is the strength significantly improved, but the hardness of the coating layer itself is further improved due to the presence of the ion-implanted component, and the coating layer does not peel off even when cutting under severe conditions.
They have discovered that it exhibits excellent wear resistance over an extremely long period of time.

に特徴を有するものである。This invention was made based on the above knowledge, and contains 5 to 30% of one or more of Co, Ni, and Fe as binder phase forming components, and the remainder is a hard dispersed phase forming component. compositional formula as
On the surface of a cermet substrate having a composition consisting of a metal carbonitride solid solution represented by (Tj, M)CN (where M consists of one or more of TaNb, W, and Mo) and inevitable impurities, A surface-coated cermet cutting tool formed by forming a single-layer coating layer consisting of one type of TiC-N.0 has the average thickness of the coating layer 0, 1= ], !
By performing ion implantation treatment in a state where the thickness is relatively thin with ozm, and allowing the ion implantation component to permeate through the coating layer to the surface of the substrate, the adhesion of the coating layer to the surface of the substrate can be improved, and the above-mentioned The present invention is characterized by a method of manufacturing a cutting tool made of surface-coated Sammet, which improves the hardness of the coating layer itself.
つぎに、この発明の方法において、上記の通り数値限定
した理由を説明する。Next, in the method of this invention, the reason for limiting the numerical values as described above will be explained.

なることから、その含有量を５〜３０％と定めた。(a) Content of binder phase-forming components in the substrate: Do these components have the effect of strongly bonding with the dispersed phase and improving the strength and toughness of the substrate? The desired effect could not be obtained, and if the content exceeded 30%, the wear resistance of the substrate would deteriorate, so the content was set at 5 to 30%.

ｍと定めた。(b) Average layer thickness of the coating layer The average layer thickness is 0.1. If the average layer thickness exceeds 1.5 μm, the wear resistance improvement effect of the coating layer formation will not be fully realized, but if the average layer thickness exceeds 1.5 μm, the current ion implantation technology will require the ion implantation component to exceed 15 μm. It is difficult to implant to a deeper depth, and the ion implantation components can only penetrate through the coating layer into the surface of the substrate, resulting in a decrease in the hardness of the coating layer itself. However, since the adhesion strength of the coating layer to the substrate surface is not improved, the average layer thickness is set to 0.1 to 1.5μ.
It was determined as m.

Methods 1 to 12 of the present invention are carried out by forming a cermet indexable tip on the surface of the present invention and subsequently subjecting it to ion implantation treatment under the conditions shown in Table 1. (referred to as coated Sammet chips) were manufactured, respectively.

満足する耐摩耗性か得られないことが明らかである。From the results shown in Table 1, the coated cermet chips of the present invention produced by methods 1 to 12 of the present invention all have excellent adhesion of the coating layer to the substrate surface and high hardness, so that the coating layer does not peel off. However, conventionally coated cermet chips that have not been subjected to ion implantation have poor adhesion of the coating layer to the Zamet substrate. It is clear that due to the relatively low hardness, peeling occurs in the coating layer, and sufficiently satisfactory abrasion resistance cannot be obtained.

It is possible to produce cutting tools made of Sammet with an enhanced surface coating due to the presence of ion-implanted components, so that even when used under harsh conditions such as high-speed cutting or heavy cutting, the coating layer does not peel off. It exhibits excellent wear resistance over an extremely long period of time.
