“…Reduced tensile residual stresses even could enhance the product functionality leading to longer product life and less environmental impact [13]. The peripheral speeds used in grinding of hardened steel with seeded-gel wheels reported in previous works do not exceed 60 m/s [2,[8][9][10]. In most of them, the peripheral speeds are considerably lower than this value.…”

“…These events led to a periodic shedding of the oxide layer and the plastically deformed grain. Starkov et al [8] found that CBN grinding wheel far outperforms in efficiency its analogs with microcrystalline corundum and white electrocorundum in profiling shaped broaches from hardened high speed at a peripheral speed of 30 m/min. Nadolny and Kaplonek [9] evaluated the effect of wear phenomena of grinding wheels with sol-gel alumina on chip formation during internal cylindrical plunge grinding of 100Cr6 steel at a peripheral speed of 60 m/min.…”

The selection of the grinding wheel is an important step during the process planning of grinding operations, especially for high-quality small components of hardened steel. The correct choice of the grinding wheel and the proper selection of cutting parameters can provide ground surfaces with high quality and positively affect the economic aspects of the process. The present work compares the performance of seeded-gel and CBN grinding wheels in external cylindrical plunge grinding of 100Cr6 steel in a range of high peripheral speeds, where it is possible to use both grinding wheels. The comparison was made taking into account the workpiece surface roughness and indices like the grinding ratio, specific grinding energy and grinding efficiency. The use of the CBN grinding wheel resulted in lower surface roughness values than those obtained with the seeded-gel grinding wheel. For both grinding wheels, there was a tendency that increasing peripheral speed reduces the surface roughness values. The best performance of the seeded-gel grinding wheel was found at 150 mm 3 /min/mm, where the grinding efficiency increased with the peripheral speed, and the highest value of all the performed experiments was achieved at 80 m/s. This value was approximately three times the grinding efficiency of the CBN grinding wheel under the same cutting conditions. The highest grinding efficiency for the CBN grinding wheel was achieved at 200 mm 3 /min/mm and 80 m/s. The grinding efficiency of the seeded-gel wheel dropped for this cutting condition due to higher wheel wear.

“…Diamondand its composites have been widely used over the years for most of the above mentioned applications. Unfortunately, these materials are not appropriate forsome applications such as machining tools made of ferrous alloys, due to the high chemical reactivity of C to Fe at elevated temperature temperatures [1][2][3][4][5]. As such, the possibility of synthesizing materials…”

We have reported on the implantation of boron ioninto hexagonal boron nitride (h-BN) material to aid the nucleation ofcubic boron nitride nanocrystals (nc-BN).Single crystal h-BN was implanted with boron ion at 150 keVat fluences of the order of 10 15 and10 17 ions/cm 2 at room temperature.High Angle Annular Dark-Field Scanning Transmission Electron Microscopy (HAADF-STEM) mapping showed a variation inimage contrast in samples irradiated to a fluence of 1×10 15 ions/cm 2. As predicted by Stopping Range and Ions in Materials (SRIM) calculations, the implanted region with the highest damage density appeared to have a bright contrast in HAADF-STEM which represented the high density c-BN symmetry. High Resolution Transmission Electron Microscopy (HRTEM) and electron diffraction measurements showed regions with nc-BN for samples implanted with low fluences and amorphous BN after implantation with high fluences indicating a fluence-related phase transition in BN. Raman spectroscopy showed the emergence of longitudinal optical frequency mode associated withc-BN after implantation.
