PENGEMBANGAN MODEL MATEMATIKA LAJU KOROSI ALUMINIUM 5083 PADA KAPAL CEPAT RUDAL 60 METER

Abstract

Abstract.The 60M Fast Missile Craft (KCR 60M) frequently encounters corrosion challenges that can compromise the strength and durability of its materials, particularly aluminum 5083. Despite its high corrosion resistance, aluminum 5083 remains susceptible to pitting and galvanic corrosion in marine environments. This study develops a mathematical model based on differential equations to predict the corrosion rate of aluminum 5083, considering variables such as corrosive ion concentration, oxygen molarity, and oxidation rate. Stability analysis was conducted to ensure system stability, and numerical simulations were employed to validate model predictions. The results indicate that the system is stable across various parameters, with the model providing accurate predictions of corrosion risks. This research contributes to more effective corrosion mitigation strategies and enhances the service life of vessels, particularly in harsh maritime applications.
