摘要： PROBLEM TO BE SOLVED: To obtain a coated cemented carbide insert good in cutting for cast iron by allowing a Ti (C, N) intermediate layer to contain a 1st inside layer of Ti (C, N) of columnar crystals and a 2nd outside layer of Ti (C, N) of equi- axed particles. SOLUTION: At first, a TiCN layer having a columnar particulate structure is formed on a substrate. This columnar particles have the width of 0.5 times the thickness of the coating layer and length of 0.5 to 0.8 times the thickness of the coating layer. The obtd. columnar TiCN layer is insufficient in adhesion to an alumina layer. Therefore, for improving the adhesion, a TiCN layer composing equi-axed particles on the coating of the columnar TiCN particles is applied. The particle size of this equi-axed particles is preferably controlled to 0.2 to 1.0 μm. Then, preferably, the total thickness of the TiCN layer of columnar crystals and the TiCN layer of equi-axed crystals is controlled to 5 to 10 μm, and the thickness of the TiCN layer of columnar crystals is controlled to from 2 μm to 90% of the above total thickness.

摘要： PROBLEM TO BE SOLVED: To improve a coated cemented carbide insert for cutting steel by allowing it to contain a cemented carbide substrate, Ti (C, N) intermediate layers of multilayers contg. a 1st inside layer of columnar particulate Ti (C, N) and a 2nd outside layer of equi-axed Ti (C, N), an Al2O3 layer and an another layer of columnar particulate Ti (C, N) on the Al2O3 layer. SOLUTION: The surface of a substrate is coated with a TiCN layer composed of columnar particles. The columnar particles have the width of 0.1 to 0.5 times the thickness of the coating layer and the length of 0.5 to 0.8 times the thickness of the coating layer. For improving the adhesion of a bonding layer, a TiCN layer composed of equi-axed particles is formed on the columnar TiCN layer. The particle size of the equi-axed particles is controlled to 0.2 to 1.0 μm. Then, the total thickness of the TiCN layers is controlled to 2 to 4 μm. The bonding layer is the one of cubic crystals of Ti (CO) contg. Al. A κAl2O3 layer on this layer has the thickness of 2 to 4 μm and is used as a thermal barrier layer. The κAl2O3 layer is protected by TiCN formed thereon.
