The work is focused on the evaluation of cadmium layer corrosion according to Boeing specification and how is the status of the underlying material influenced by the corrosion. Plating was applied on the steel panels (type 4130). These metal sheets were partially corroded, therefore there were chosen various surface pretreatment, which removed the corrosion attack and subsequently cadmium plating was carried out. Corrosion neutral salt spray test for 336 hours was done according to ASTM B117.
