Laser embedding of TiC particles into the surface of phosphor bronze-bearing material
journal contribution
posted on 2023-06-08, 12:00 authored by B S Yilbas, S S Akhtar, C Karatas, Chris ChatwinChris ChatwinA carbon film containing 5% TiC particles is formed on a pre-prepared bronze surface prior to laser treatment. The carbon film provides increased absorption of the incident laser beam and hosts TiC particles with a uniform distribution at the workpiece surface. Optical and scanning electron microscopy are used to examine the metallurgical and morphological changes in the laser treated layer. Micro-hardness of the laser-treated surface is measured, and the residual stress formed in the surface vicinity is measured using the X-ray diffraction technique. It was found that a dense layer with fine grains was formed in the laser-treated layer. The micro-hardness of the laser-treated surface increases almost three times compared with the base material hardness. The presence of a dense layer and the formation of Cu 3N in the surface region contribute to the hardness enhancement at the surface. Copyright © 2012 John Wiley & Sons, Ltd.
