摘要 |
A tool coated with a hard Ti/B layer having fine boron nitride particles dispersed therein, wherein the bonding energy of B and N is observed in an ESCA analysis of the hard coating layer; wherein peaks of c-BN and h-BN is detected in an Raman spectroscopy of the hard coating layer; wherein a ratio Q1/Q2 of a peak intensity Q1 of c-BN to a peak intensity Q2 of h-BN is 1.0 or more; wherein a half-value width Z of a (200) face in an X-ray diffraction of the hard coating layer is in a range of 0.3 DEG to 0.6 DEG ; and wherein a ratio K/L of a face thickness K to a flank thickness L in the tool is 1.0 or more, whereby the hard coating layer has high hardness, high lubricating properties and excellent crater wear resistance, with chemical reactions with a work suppressed. <IMAGE> |
