Cadmium electrochemistry coatings on carbon steel have strong corrosion resistance, especially in marine environments, low friction coefficient and afford a good electrical contact. They are used by the petroleum, automotive, electric and electronic industries and moreover in locks production. In Brazil, due to their good performance in salty environments, these coatings are still widely used. However, its use diverse, before his toxicity not propagated and the low melting point may result in restrictions on some industries like food and pharmaceuticals. Cadmium is regarded today as one of the largest metal toxicity. According to surveys conducted in 2005 by American agencies ATSDR (Agency for Toxic Substances and Disease Registry) and EPA (Environmental Protection Agency) cadmium occupies the 7th place in toxic substances with increased risk of harm to humans. This work aims to show the processes of cadmium coating deposition, its advantages and disadvantages, at the same time alert regarding the problems caused by cadmium in environment and the possible health problems caused by cadmium absorption.
