“…The most common systems for the production of tool mate rials in the BL group are the cBN-TiC, cBN-TiN, and cBN-Ti(C,N) systems with a minor amount of Al introduced as a getter of oxygen [3]. It is known that the tool materials of BL group exhibit much higher per formance than composites of BH group in finish turning of hardened steels [4] and heat resistant nickel alloys [5].…”

The article presents a study of the potential for the use of B 6 O superhard boron suboxide as a binder in composite materials with a low cBN content. Superhard B 6 O is characterized by higher mechan ical properties than TiC widely used in commercial materials today. Composites containing 60 vol % cBN and different binder compositions that included B 6 O and TiC have been sintered in a toroid type high pressure apparatus at a pressure of 7.7 GPa in a temperature range from 1500 to 2000°C. The microstruc ture, phase and elemental composition of the sintered materials have been examined via electron micros copy and X ray diffraction analysis. Mechanical properties have been analyzed via indentation techniques. The performance of the cutting tools produced from the sintered composites has been evaluated in turning hardened cold work tool steel.

“…Additionally, the influence of PCBN composition on the interaction was investigated. It is known that high-cBN tools have a higher wear rate in continuous machining than low-cBN materials with ceramic binders [14]. Therefore, this study also aims to investigate the mechanisms responsible for the discrepancy in wear between high-and low-cBN tool materials.…”

On chemical and diffusional interactions between PCBN and superalloy Inconel 718Imitational experiments Bushlya, V.; Bjerke, A.; Turkevich, V. Z.; Lenrick, F.; Petrusha, I. A.; Cherednichenko, K. A.; Ståhl, J. E. AbstractDuring a metal cutting process, chemical wear can become the dominant mechanism of tool degradation under the high temperatures and contact pressures that arise between the tool and the metal workpiece. This study focuses on the chemical and diffusional interactions between superalloy Inconel 718 and cubic boron nitride (cBN) tool material with and without TiC binder. It covers thermodynamic modeling and experimental tests in the pressure range of 0.1 Pa to 2.5 GPa at temperatures up to 1600 °C. The methods used include diffusion couples under both vacuum and high pressure, transmission electron microscopy (TEM) analysis and in-situ synchrotron observations. It is shown that cBN is prone to diffusional dissolution in the metal and to reactions with niobium, molybdenum, and chromium from Inconel 718. Adding TiC binder changes the overall degradation process because it is less susceptible to these interaction mechanisms.

“…The wear of PCBN wedges is one of the most frequent research issues in the area of machining of hardened materials. According to [2][3][4], two groups of PCBN-based tool materials can be distinguished: a) Low-cBN (cBN-L), which contains a lower (40-65 %) cBN volume fraction in the tool material, most often with a ceramic binder (e.g., TiC, TiN), typically dedicated to continuous hard machining, usually with single-or multilayer antiwear coating; b) High-cBN (cBN-H), which contains a high (70-95 %) cBN volume fraction in the tool material, most often with a metallic binder, recommended for interrupted hard machining.…”

On the wear comparative analysis of cutting tools made of composite materials based on polycrystalline cubic boron nitride when finish turning of AISI D2 (EN X153CrMoV12) steelThis study presents the results of research on the condition of low content polycrystalline cubic boron nitride cutting tools (cBN-L) when finish turning of hardened AISI D2 tool steel. The least changes in the condition of wedges throughout the investigated turning feeds were observed for the composite cBN020 whereas the highest wear intensity was found for the composite cBN200. For all researched cutting materials, abrasive wear, as well intense adhesion were observed.
