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

Photoluminescence spectroscopy of electron‐irradiation induced defects in cubic boron nitride (cBN)
physica status solidi (c), 2004Cubic boron nitride is an ultra-hard material that is widely used in industrial applications where its specific mechanical properties make it the material of choice. Compared to diamond, which has similar applications, relatively little is known about the defects in cBN, their structure, electronic properties and their possible effects on the ...

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.

Abstract This paper describes a comparison of tool life between ceramics and cubic boron nitride (CBN) cutting tools when machining hardened bearing steels using the Taguchi method. An orthogonal design, signal-to-noise ratio (S/N) and analysis of variance (ANOVA) were employed to determine the effective cutting parameters on the tool life.

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.

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

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 ...

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 ...
