Title:
切削工具用ダイヤモンド皮膜
Document Type and Number:
Japanese Patent JP6927954
Kind Code:
B2
Abstract:
There is provided a diamond film for cutting tools that has excellent adhesiveness with a base material, exhibits excellent abrasion resistance and deposition resistance even when used to machine a composite including a hard-to-cut material and a material susceptible to deposition, and can exhibit excellent cutting performance over a long period of time. This diamond film for cutting tools is formed on a base material, in which assuming a Raman scattering spectrum measured by spectroscopic analysis of Raman scattering is the sum of seven predetermined Gaussian functions, and when the peaks of the Raman scattering spectrum are separated, an intensity ratio [IN/IJ] of a peak intensity IJ and a peak intensity IN of the predetermined Gaussian functions is 0.01-0.30 (inclusive) at an arbitrary measurement position A in a range of 0.5µm in a film surface direction from a base material surface, and is 1.00-30.25 (inclusive) at an arbitrary measurement position B in a range of 0.5µm in a base material direction from a film surface.
