Abstract

Penelitian ini bertujuan untuk mempelajari korosi pada baja galvanis setelah diekspos di Sungai Cidaho Wilayah Sukabumi, Jawa Barat. Kehilangan berat baja galvanis diukur dengan metode pengurangan berat setelah diekspos untuk periode waktu tertentu di permukaan air sungai dan kedalaman air 1 meter. Morfologi permukaan dan komposisi produk korosinya dianalisismenggunakan Scanning Electron Microscopy (SEM) - Energy Dispersive Spectroscopy (EDS) dan X-Raya Diffraction (XRD). Setelah diekspos, seluruh permukaan baja galvanis tertutup oleh produk korosi. Hasil berat yang hilang dari baja galvanis setelah diekspos 76 hari adalah 1,37 mg/cm2 pada permukaan air sungai dan 7,83 mg/cm2 untuk kedalaman air 1 meter. Peningkatan kerusakan dari baja galvanis ini terjadi karena tidak terbentuk lapisan protektif akibat tergerus arus sungai. Produk korosi yang dominan pada baja galvanis yang diekspos pada kedalaman 1 meter adalah senyawa Zincite (ZnO). Hasil ini mengindikasikan bahwa penggunaan baja galvanis tidak cocok untuk lingkungan di kedalaman air

Abstract

Medical applications occasionally require PSI (patient-specific implant) designs to match the implant bone’s geometry. To verify and predict failures of the design as well as a treatment before the manufacturing process, FEA (finite element analysis) is employed to simulate when given a specific number of loads. Plenty of studies have done the FEA using a couple of types of software; however, to the best of our knowledge, there is no literature to compare those several FEA results with a comparable experiment. This study further analyzes material stress, particularly to compute the VMS (Von Misses stress) of the Ti6Al4V bone plate. Furthermore, this study proposes to examine and deliver a comprehensive understanding using the four most used software of COMSOL, Ansys, Abaqus, and Autodesk Inventor. The results of those four simulations are then compared with the stress test through the Hardness Vickers test. This study will contribute significantly as a novel comparison between VMS and hardness test as a stress prediction in an implant material.
