Properties of Tin Films Electrodeposited under a Weak Magnetic Field

Resumo

The cathodic deposition of tin coatings was performed from a sulfuric acid solution containing solely tin(II) sulfate, under a continuous external magnetic field. The influence of this magnetic field on the electrodeposition process, morphology and physical-mechanical properties of the tin film is reported. The morphology of the coatings was observed by scanning electron microscopy. It is shown that the tin electrodeposited under a weak (from 0.0005 to 0.0025 T) magnetic field has changed its surface morphology and physical- mechanical properties.
