ところである。DETAILED DESCRIPTION OF THE INVENTION The present invention can be used as a cutting tool for cutting steel and cast iron, especially for heavy cutting such as high-speed cutting of these corrugated materials, high feed cutting angle IJ, and deep cutting. This relates to a surface-coated cemented carbide member that exhibits excellent cutting performance. In general, the hard dispersed phase is mainly composed of elements 4a and 5 of the periodic table.
a, and one or more of carbides, nitrides, and carbonitrides of group 6a metals, while the binder phase is mainly one or more of iron group metals, or iron group metals. Similarly, -4a, +5 is applied to the surface of a superhard alloy substrate composed of one or more metals and one or more of chromium group metals and M.
A coating layer consisting of a single layer or a multilayer of two or more of the group consisting of carbides, nitrides, and oxides of group a + and group 6a metals, and solid solutions of two or more of these metals is formed by chemical vapor deposition. It is well known that surface-coated cemented carbide members formed by such methods are used as cutting tools.

It reaches the end of its useful life in time,
On the contrary, Takadaike's product shows excellent performance when cutting cast iron and has a comparatively long service life, but it has a short cutting life when cutting steel. It does not exhibit satisfactory cutting performance in any of these cutting operations, and even more so, it does not demonstrate satisfactory cutting performance in any of these cutting operations.
Of course, this applies to cutting under severe conditions such as heavy cutting such as high feed cutting and deep cutting.

In a reduced pressure atmosphere, using a mixed reaction gas consisting of AlC11s, CO2, N2, f(2, and Ar), a negative voltage or high frequency is applied to the substrate to generate a glow discharge, thereby activating the atmosphere and discharging the substrate.

由によるものである。Furthermore, it is desirable that the average layer thickness of the AlCN0 coating layer of the present invention is 0.5 to 20 μm, because if the average layer thickness is less than 0.5 μm, the desired excellent cutting performance cannot be maintained for a long period of time. On the other hand, 20IrrL
If the layer thickness exceeds 9, the coating treatment time becomes longer, which causes the crystals to become coarser and the toughness to decrease.9 This is not only due to the fact that the surface becomes rough and uneven. It is.
