Abstract

Investigation Exploration Outcome of Heat Treatment on Corrosion Resistance of Aa 5083 in Marine Application

Author(s): S. P. SUNDAR SINGH SIVAM, ABBURI LAKSHMAN KUMAR, K. SATHIYA MOORTHY and RAJENDRA KUMAR

Aluminum alloy 5083 is commonly used in the ship building application in marine environment and susceptible to corrosion when they are run at high speed velocity, high flow rate condition and stagnate condition. Therefore, solution heat treatment was carried out to prevent corrosion. The optimal heat treatment involved heating specimens for 90 min at 400°C and then cooling them in water. In addition, the optimal artificial aging condition involved aging specimens for 120 min at 200°C. The corrosion rates of the heat treated specimens were determined using weight loss method. The immersion test has done for 2 weeks. The microstructures of heat treated specimens have been observed using optical electron microscope. The corrosion resistance of heat treated specimens increased after solution heat treatment and the hardness of the specimens also increased.
