RESUMO

The objective of this work is to evaluate the corrosion resistance of Brass C360 samples coated with INCONEL 600 films, obtained by the plasma at configuration Triodo agnetron Sputtering (TMS) technique. In order to compare had been deposited films with different parameters (time of deposition and potential to the substrate) obtaining coatings with different characteristics (thicknesses, density, porosity and stress in film). Brass samples electrochemical behavior was investigated by the consist of polarize the samples of immersed test in a solution of NaCl 3.5%, to evaluate the corrosion resistance of the samples. The results show that all INCONEL 600 the films improved its corrosion resistance to the Brass substrate being more efficient the films with more time of deposition and more potential applied in the substrate.
