Abstract

The micro-texture fabricated on the cubic boron nitride (CBN) tool surface is an established method for enhancing the penetration ability of nanofluids into the tool/chip interface. However, achieving efficient and continuous cooling lubrication at the micro-textured tool/chip interface continues to pose significant challenges. In this study, we employed an external magnetic field to enhance the permeability of nanofluids, while also taking into account the effects of electroosmosis. The turning experiments conducted on superalloys using micro-textured CBN tools (named TSN) have validated the effectiveness of the proposed method. By increasing the magnetic field intensity to 1200 Gs and integrating an electroosmotic accelerator into Fe₃O₄ nanofluids, the anti-wear properties of TSN were enhanced. This enhancement resulted in a reduction of cutting force by approximately 18 %, a decrease in cutting temperature by 9.1 %, and a reduction in surface roughness of machined workpiece by 43.04 %. Finally, the mechanism was discussed.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
