One of the problems related to the gray cast iron cylinder liner, and others materials, transportation is the possibility of the surface corrosion due to a non-controlled environment. The manufacturer has the responsability to guarantee the product free of corrosion up to the opening at final destination. Aiming to evaluate the liners transportation, regarding the corrosion potential during the transportation cycle, Magneti Marelli Cofap did experiments where the atmospheric conditions inside the pallets were measured. Using a special device it was possible to check the temperature, absolute humidity and relative humidity variations at every step, which were pre-set by using an specific software. The main reason for variations that might happen at the liner surface are related to transportation and storage. The corrosion rate will be determined by physical and chemical atmospheric conditions.
