The effect of pH upon corrosion rate of aircraft component type MD 80 on fuselage part

摘要

Indonesia as one of the archipelagic countries with 16,055 islands and has been registered with PBB certainly requires transportation facilities that can reach all areas of the country.The most efficient and effective mode of transportation to reach all islands in Indonesia is aircraft.Along with the increasing number of users it will increase the number of requests in the level of comfort and safety of passengers one of which is in the feasibility of an aircraft.This research aims to study the effect of pH upon corrosion rate of aircraft metal material type of MD 80 on fuselage part.This study employed pH at 3.4; 3.8; 4.4; 4.8; 5.4; 5.8; 6.1; 7.5; and 12 at fixed temperature of 30°C.Weight loss of aircraft metal material were measured once every 1 hour.The results of this study conclude that the effect of pH upon corrosion rate of aircraft type MD 80 metal material on the fuselage part at a fixed temperature of 30°C in a span of 12 hours showed less significant results.This might be due to the corrosion rate of aircraft metal components running very slowly so that in the span of 12 hours,no significant results were obtained.
