切削工具での表面被膜は主に硬度の向上に向けられ、耐
熱性の配慮に欠けるという問題があった。Considering the usage conditions of the cutting tool, there is a problem of oxidation due to heat generation at the contact portion. For example, it has been reported that the wear at the contact area between the cutting tool and the workpiece can be significantly reduced by cutting in an inert gas. However, the surface coatings of conventional cutting tools are mainly aimed at improving hardness, and there is a problem in that they lack consideration for heat resistance.
このようなことから、最近、耐熱性を考慮した被膜とし

) Expressed by N, changes in hardness and heat resistance with respect to X were investigated, and the following facts were found.
■、前記被膜の硬度は、Ｘが０．４〜０．５の範囲で最
大となり、ＴｉＮと同等もしくはそれ以上となるが、Ｘ
を更に増加させると硬度が急激に低下する。(2) The hardness of the coating reaches its maximum when X is in the range of 0.4 to 0.5, and is equal to or higher than TiN, but
Further increasing the hardness causes a sudden decrease in hardness.
■、前記被膜の耐熱性は、８００℃、大気中での加熱試

上で良好な特性を示す。(2) The heat resistance of the coating is evaluated by the oxidation weight gain value in a heating test at 800° C. in the air, and shows good characteristics especially when X is 0.7 or more.
このように前記（Ｔ ｌ １−ｘ Ａり ｘ ） Ｎ被
膜では、耐熱性を重視してＡｌ量を増すと硬度の低下が
避けられないという問題がある。As described above, the above-mentioned (Tl1-xArix)N film has a problem in that when the amount of Al is increased with emphasis on heat resistance, a decrease in hardness is unavoidable.
本発明は上記従来の問題点を解決するためになされたも

具鋼、超硬合金等を挙げることかできる。Examples of the metal base material include stainless steel, high-speed tool steel, cemented carbide, and the like.
前記被膜のＡｇ量（ｘ）を限定した理由は、Ｘが０．８
を越えると硬度（耐摩耗性）が低下するからである。The reason for limiting the amount of Ag (x) in the coating is that X is 0.8
This is because hardness (wear resistance) decreases if it exceeds this range.
