چکیده
In order to understand the surface and interface conditions of polycrystalline cubic boron nitride (PcBN) sliding against bearing steel in vacuum environments, effects different loads on tribological behaviors PcBN AISI 52100 were studied deeply a tribometer. Furthermore, wear tracks scars characterized by scanning electron microscopy energy dispersive X-ray spectroscopy. The results show that stable coefficient friction (CoF) tribopair experiences decrease first then an increase with from 2 N 15 N. adhesive layer increases loads, formation contributes change CoF rate counterpart balls. is formed due combination high contact stress temperature. Meanwhile, exfoliated grains are embedded into as abrasive grains, resulting wear. Thus, main mechanisms

Transparent polycrystalline cubic silicon nitride
Glasses and single crystals have traditionally been used as optical windows. Recently, there has been a high demand for harder and tougher optical windows that are able to endure severe conditions. Transparent polycrystalline ceramics can fulfill this demand because of their superior mechanical properties. It is known that polycrystalline ceramics with a spinel structure in compositions of MgAl...

متن کاملMechanical properties of polycrystalline boron-nitride nanosheets
The first molecular dynamics (MD) study was conducted to explore mechanical-failure response of ultrafine grained single-layer boron-nitride films. We used MD simulations to construct relatively large molecular models of polycrystalline structures with random grain configurations. By applying uniaxial tensile loading, we then studied the grain size effect on the mechanical response of polycryst...
متن کاملA quantitative analysis of a multi-phase polycrystalline cubic boron nitride tool material using DualEELS.
This paper presents a quantitative analysis of a polycrystalline cubic boron nitride tool material by electron energy-loss spectroscopy spectrum imaging acquired in dual range mode. Having both the low-loss and core-loss regions acquired nearly simultaneously provides the advantage of accurate corrections for thickness effects and thus the possibility to perform quantification calculations. Thi...
متن کاملTribological Characteristics of the Surface Layer of Steel Modified with Boron under Mixed Friction Conditions
The aim of the present work is to determine the influence of technologically produced boron surface layers on the friction parameters in the sliding pairs under mixed friction conditions. The current boronizing processes allow obtaining surface layers of high hardness and high resistance to corrosion and wear, with low brittleness and no tendencies towards cracking However, the operation charac...
