| Abstract Scope |
Due to explosive growth of electric vehicle market, production of aluminum-based automotive parts has been increasing rapidily. Generally, A383 aluminum alloy and high pressure die casting were used to manufacture automotive parts which have complex dimensions and thin wall thickness. In case of housing components for electric motor, their corrosion resistance as well as their mechanical and thermal properties is important, especially at the cooling channel surface. In the present study, corrosion behavior of high pressure die cast A383 aluminum alloys was investigated at different surface conditions (as-cast, shot-blasted, machined, and polymer-impregnated) under a high temperature (~40°C) and humidity (>95% RH) condition. After maximum 18 hrs of corrosion test in a humidity cabinet, surfaces and microstructures of the A383 samples were examined. From the experimental results, effect of surface condition on corrosion behavior of the high pressure die cast A383 aluminum alloys were discussed. |
