SINTERED OBJECT OF CUBIC BORON NITRIDE AND COATED SINTERED OBJECT OF CUBIC BORON NITRIDE

WIPO Patent Application WO/2014/175419

A1

The purpose of the present invention is to provide a sintered object which contains cubic boron nitride and is excellent in terms of wear resistance and chipping resistance. The sintered object of cubic boron nitride comprises cubic boron nitride, a binder phase, and unavoidable impurities, wherein the binder phase comprises at least one element selected from the group consisting of Zr, Hf, V, Nb, Ta, Cr, Mo, and W and a composite solid-solution compound of Ti, the composite solid-solution compound having an NaCl structure and, in an examination by X-ray diffractometry conducted by the 2θ/θ method using a CuKα line, giving a diffraction line assigned to the (200) plane of the composite solid-solution compound, the diffraction line having a half-band width of 0.60°-0.90°.
