    The invention relates to powder metallurgy, in particular to re-. tools made of sintered hard alloys. A cutting tool made of sintered hard alloy containing tungsten carbide and cobalt TI is known. The closest to the proposed technical essence and the achieved result is a cutting tool containing a substrate of sintered hard alloy based on tungsten carbide with cobalt and a surface layer of titanium carbide A disadvantage of the known cutting tools is their low durability. The purpose of the invention is to increase the service life. The goal is achieved by the fact that the cutting tool, containing a substrate of sintered hard alloy based on tungsten carbide with cobalt and a layer of titanium carbide, further comprises an outer layer of aluminum oxide 0.8–2 µm thick, with an atom thickness of titanium double is 2-5 microns. The deposition of titanium carbide and alumina layers on the sintered hard alloy is carried out from the gas phase. Before applying a layer of titanium carbide, the surface of the hard alloy can be oxidized or nitrated. It is possible to oxidize the TiC layer before applying the alumina layer. The oxidation step is carried out independently. ..: In order to increase the service life of the publication, it is necessary that the titanium carbide layer be uniform and have good adhesion to the substrate. In order to ensure the optimal structure of the titanium carbide layer, it is necessary that the rate of the deposition process be low. Example 1. On a substrate of sintered hard alloy based on tungsten carbide, containing, wt.% 1 cobalt 9.5; titanium carbide 12,0j tantalum carbide 6.0; niobium carbide; 4.0; tungsten carbide - the rest, with deposited layer of titanium carbide from the gas phase, containing,%: TiC 10; SND 8; . The layer of alumina is applied at the same temperature () from the gas phase containing,%: CO 5 CO 20; A1C15 5. Cutting tests of carbon steel with 1% C (Brinell hardness 300 kg / mm) at cutting speeds of 1 bO m / min, feeding 0.30 mm / rev show the following values for tool life, min: Hard alloy 3.3 Hard alloy + + Tie layer, 4 microns {prototype) 15.5 Hard alloy + + layer, Hard alloy + + 30 micron layer Hard alloy + + TiC layer, 2 MKM + + layer, 2 microns Example 2, On a sintered substrate hard alloy composition, vol.%: cobalt 9.5; karbid titanium 15.5; Wolfram carbide . the rest is applied first with a layer of TiC, then with a layer of AA1a. the gas phase of the composition, given in ca 1, at. When steel was cut with hardness, Brinell 280 kg / mm at a cutting speed of 180 m / min and a feed of 0.3 mm / rev were installed after the service life of the tool, min: Hard alloy + TiC layer, .5 µm (prototype) 14.4 Solid alloy + layer. Tie, 5 μm + layer, 0.8 μm63.5 / As follows from the above data, the application of the outer layer of aluminum oxide with a thickness of 0.8-2 μm on a substrate of sintered hard tungsten carbide-based alloy with a layer of titanium carbide 2- thick 5 microns increases the service life of the cutting tool by 2.8-4.3 times. DETAILED DESCRIPTION OF THE INVENTION A cutting tool comprising a substrate of sintered hard tungsten carbide based on cobalt and a layer of titanium carbide, characterized in that, in order to increase the service life, it additionally contains an outer layer of alumina 0.8-2 microns thick, wherein the thickness of the titanium carbide layer is 2-5 µm.
