Abstract

Magnesium adalah salah satu kandidat base material dari biodegradable implant yang sedang banyak diteliti. Magnesium merupakan material alami yang dibutuhkan untuk membentuk enzim di dalam tubuh dan memiliki sifat mekanik yang mirip seperti tulang alami. Tetapi paduan magnesium memiliki kekurangan yaitu sangat mudah terdegradasi Maka dari itu dikembangkan penelitian untuk meningkatkan performa paduan magnesium sebagai base material dari biodegradable implant. Pada paper review kali ini dilakukan perbandingan pengaruh Lapisan tipis Ca-P dari material hydroxyapatite dan lapisan tipis Ta2O5 dari material tantalum sebagai surface treatment terhadap laju degradasi dan sifat biocompatibility dari paduan magnesium. Berbagai macam metode dipilih untuk mendapatkan perbandingan yang terbaik. Beberapa metode yang disertakan adalah Physical Vapour Deposition (PVD), Atomic Layer Deposition (ALD), Elecphoretic Deposition (ELD), dan Micro-Arc Oxidation (MAO). Evaluasi laju degradasi dilakukan dengan menggunakan metode Potensiodynamic Polarization dan Electrochemical Impedance Spectroscopy. Kedua lapisan tipis tersebut berhasil menurunkan laju degradasi secara signifikan dengan mekanisme proteksi masing-masing. Pengujian sifat biocompatibility dilakukan dengan metode Direct Cell Adhesion dan Indirect Cell Proliferation ditambah evaluasi secara kuantitatif dengan menggunakan metode MTT Assay. Kedua lapisan tipis mampu menjadikan paduan magnesium sebagai media yang stabil untuk perkembangan dari sel yang dikultur. ==================================================================================================================== Magnesium is one of the base materials candidate for biodegradable implants that is being developed. Magnesium is a natural material needed to form enzymes in the body and has mechanical properties similar to natural bone. But magnesium alloy has the disadvantage of being very easily corroded. Therefore, research was developed to improve the performance of magnesium alloys as biodegradable implants. In this paper review a comparison of the effect of Ca-P thin film from hydroxyapatite and Ta2O5 thin films from tantalum material as surface treatment on the degradation rate and biocompatibility properties of magnesium alloys. Various methods are chosen to get the best comparison. Some of the methods included are Physical Vapor Deposition (PVD), Atomic Layer Deposition (ALD), Elecphoretic Deposition (ELD), and Micro-Arc Oxidation (MAO). The degradation rate evaluation was carried out using the Potensiodynamic Polarization method and Electrochemical Impedance Spectroscopy. Both of these films succeeded in reducing the rate of degradation significantly with their respective protection mechanisms. Biocompatibility testing is done by Direct Cell Adhesion and Indirect Cell Poliferation methods plus quantitative evaluation using the MTT Assay method. Both thin layers are able to make magnesium alloy as a stable medium for the growth of cultured cells.
