METHOD FOR SELECTING TEMPERATURE OF ANODIC OXIDATION ELECTROLYTE TO PREVENT CAVITATION DAMAGE OF ALUMINUM ALLOY FOR MARINE ENVIRONMENT

摘要

In a method for selecting temperature of an anodic oxidation electrolyte of an aluminum alloy through an electrochemical experiment and a cavitation experiment, the present invention is to provide a method for selecting temperature of an anodic oxidation electrolyte to prevent cavitation damage of the aluminum alloy for marine environment where the temperature of the electrolyte is 10°C. The present invention has the effect of showing excellent durability in the seawater as stability of pore growth is changed because of activity of ion and electrolysis voltage difference in accordance with temperature variation of the electrolyte. Also, technology development to improve corrosion resistance and erosion resistance of an aluminum ship of the present invention has the effect of maximizing economic effect by reducing period and costs according to maintenance. Especially, the present invention has the effect of being able to improve durability and use lifespan by reducing frictional resistance of the ship by mitigating cavitation damage.;COPYRIGHT KIPO 2016
