Surface Roughness Characterization of Medical Implant Material SS316L Stainless Steel after Cut with Water Jet Cutting Process

Abstract

In this paper, the effect of abrasive water jet cutting process on the surface character of medical implant SS316L was investigated. This research focuses on the effect of traverse speed during abrasive water jet cutting on the surface roughness and topography of medical implant material SS316L. In some study, it has been noted that the roughness of implant material correlates with the healing process of a sufferer in medical application. Furthermore, transverse speed has an important role in the manufacturing process that correlates directly with the ability of technic to produce a product at a definite time. Garnet was used as an abrasive material in this water jet cutting process. The process was taking place in room temperature with 3000Psi of water pressure. In this study, the surface roughness was examined at all point of depth of the cut surface in all of the transverse speed using Mitutoyo SJ 210, while the surface topography observed by Olympus BX53M optical microscope. The study results reveal that traverse speed has a significant effect on the surface roughness at the surface, middle, and bottom of the cut point. The Surface roughness increase as transverse speed.

Pengaruh Tekanan Pemotongan Terhadap Laju Korosi Stainless Steel 316l Dengan Proses Abrasive Water Jet Cutting (Awj)

“…Ketahanan korosi material sangat dipengaruhi oleh kondisi permukaan dari material termasuk Stainless stell 316L walaupun Stainless steel 316L mempunyai mempunyai sifat yang superior untuk ketahanan korosinya [13,14,15]. Superioritas ini di karenakan adanya lapisan Chromium (Cr) pada stainless steel.…”

Effect of Stand of Distance (SOD) of Abrasive Water Jet Cutting processes on the Corrosion Properties of Material implant Stainless Steel 316L

“…The cutting process in abrasive water jet cutting is considered environmentally friendly because it does not produce waste that damages the environment. Because of this ability, abrasive water jet cutiing is more cost effective because water and abrasives are easy to recycle and also reduce Heat Afected Zone [1] This process is quite similar to natural water erosion, although it is much faster and more concentrated. Where is the most recommended method when cutting is carried out at room temperature without heating the workpiece.…”
