20100034603 | Surface Coated Tool and Method of Working Cutting Object - A surface coated tool comprises a substrate and a coating layer superimposed on the surface of the substrate and containing Ti and W in the form of nitride or carbonitride. The coating layer comprises a matrix and dispersed particles dispersed into the matrix. The W content of the dispersed particles is larger than the W content of the matrix, and a difference in the W content between the matrix and the dispersed particles is larger than a difference in other ingredient content. A cutting tool consisting of the surface coated tool and having a cutting edge is prepared, and the cutting edge of the cutting tool is brought into contact with a cutting object, and the cutting object is cut by the cutting tool. | 02-11-2010 |
