Fabrication and properties of Mo contacts to amorphous cubic boron nitride (a-cBN) layers
Diamond and Related Materials, 1996Abstract Mo contacts of areas varying from 2.4 to 9.4 mm2 were electron beam deposited onto undoped and sulphur doped a-cBN layers. Layers were grown by the reactive pulse plasma method on oxidized, or oxidized and subsequently covered with Au, silicon substrates.

An Expert System of Cubic Boron Nitride (CBN) Grinding Wheel Dressing in Cam Grinding
Materials and Manufacturing Processes, 2012Rule based reasoning (RBR) embodied in cam grinding will extend the application of knowledge-based system by utilizing previous knowledge and experience. However, it is very difficult to make rules without exact exceptions. Knowledge acquisition also is a bottleneck problem.

Cubic boron nitride (cBN) particle-dispersed-aluminum (Al) matrix composites were fabricated from the powder mixture composed of cBN, pure Al and Al-5mass% Si alloy in liquid and solid co-existent state by spark plasma sintering (SPS) process. Al/cBN composites were well consolidated by heating at a temperature range between 798 K and 876 K for 1.56 ks

Growth conditions of the cubic phase cBN in boron nitride films
Thin Solid Films, 2006The nucleation and the subsequent coalescence period of the cubic phase cBN in sputter deposited BN-films is characterized by a shrinking of the film thickness. This is due to the transition of hBN into the denser cBN-phase which occurs inside a highly textured hBN base layer.

Influence of Cutting Force on Bimetallic Piston Machining by a Cubic Boron Nitride (CBN) Tool
Materials and Manufacturing Processes, 2012Bimetallic pistons are most widely used in diesel engine vehicles for weight reduction and enhanced performance with long life. Aluminum alloy is reinforced with cast iron insert to realize the bimetallic pistons. The bonding between aluminum and cast iron is achieved through a patented process named the Al-Fin process.

Titanium has been perceived as a material that is difficult to machine. Manufacturers are known that, with proper procedures, titanium can be fabricated using techniques no more difficult than those used for machining SS316. The machining of hard workpiece materials requires significantly harder cutting materials. Advancements in the aerospace, nuclear

Abstract Deposition of cBN (5∼20 μm) is of great technological importance but poses significant difficulty in terms of depositing it from vapor phase(s). Initial proof-of-concept work has indicated that a thick cBN–TiN composite coating can be deposited in a practical hybrid deposition process using electrostatic spray coating (ESC) and chemical ...

In this article, cubic boron nitride (CBN) and coated carbide tools were used for finish turning of hardened steel with continuous and interrupted surfaces. The objective of this work is to investigate the conditions under which carbide tools can give optimal results in terms of both tool wear and surface integrity of the machined surface in comparison

It has been concluded in previous studies that Cubic Boron Nitride (CBN) tools have greater wear resistance and superior tool life than other tool materials used in conventional milling, due to chemically stability at high temperatures, high abrasive wear resistance and high degree of hardness; however no research has been conducted about its ...

Abstract The Ti coatings on cubic boron nitride (cBN) grits were prepared by discharge treatment on a mixture of Ti powders and cBN grits in spark plasma sintering system. The uniform and full coatings with a thickness of ∼1.2 μm were prepared at 850 °C for 60 min, which were constituted with TiB2, TiN, and Ti phases.
