    摘要: A coated sintered cemented carbide body includes a cemented carbide body, a first layer adjacent the cemented carbide body, the first layer including Ti(C,N) and having a thickness of from about 3 to about 20 &mgr;m, an alumina layer adjacent said first layer, the alumina layer including &agr;-Al2O3 or &kgr;-Al2O3 and having a thickness of from about 1 to about 15 &mgr;m, and a further layer adjacent the aluminum layer of a carbide, carbonitride or carboxynitride of one or more of Ti, Zr and Hf, the further layer having a thickness of from about 1 to 15 &mgr;m. A friction-reducing layer, including one or more of &ggr;-Al2O3, &kgr;-Al2O3 and nanocrystalline Ti(C,N) and having a thickness of from about 1 to about 5 &mgr;m, can be adjacent to the further layer. A method to cut steel with a sintered cemented carbide body where the alumina is &agr;-Al2O3 and a method to cut cast iron with a sintered cemented carbide body where the alumina is &agr;-Al2O3.

    摘要: A coated cemented carbide insert is particularly useful for wet or dry milling steels at high cutting speeds, milling of hardened steels, and high feed copy milling of tool steels. The insert is formed by a cemented carbide body including WC, NbC and TaC, a W-alloyed Co binder phase, and a coating including an innermost layer of TiCxNyOz, with equiaxed grains, a layer of TiCxNyOz with columnar grains and a layer of α-Al2O3.
