Abstract

This work studied the potential difference and galvanic currents on particulate contamination of the abrasive on the patterned surface and on corrosion behaviors of TiN and W. The polarization curves of TiN and W were, respectively, obtained in 0.01mol/L KNO₃ solutions in the absence and presence of three typical oxidants (H₂O_2, KIO₃, Fe(NO₃)₃) by DC polarization technique. The corrsion potentials and galvaniccurrents were measured when TiN and W were placed in a specially designed electr-chemical cell to form electro-couple. The preliminary results revealed that the corrosionrate of TiN-W electro-couple significantly increased in the presence of 4.5% H₂O₂, at pH 4.0 , while reduced to the minimal in the presence of Fe(NO₃)₃ at pH 1.5. Agitationsignificantly enhanced the cormsion rate of TiN-W couple.
