Study on the anticorrosion capability of TiC_xN_(1-x) aluminum foil electrical pole material

Through polarization curve experiment and dip-in eroding experiment,the anticorrosion capacity was analyzed contrastively between the aluminum foil sample with TiCxN1-x coatings manufactured under the best deposition techniques and that of the aluminum foil sample which made by complex eroding method.The results show that in acidic liquor,the self-eroding potential Ecorr of TiCxN1-x coating aluminum foil is 50 mV higher and the current density is 0.914×10-3 A/cm2 lower than those of the aluminum foil which is made by complex eroding method,that is to say TiCxN1-x coating aluminum foil possesses better anticorrosion capacity than eroding aluminum foil.The dip-in experiment also shows the same result because after 9 h dip-in,the aluminum foil sample which is made by complex eroding method is perforated by corrosion while the aluminum foil sample with TiCxN1-x coatings have little change.
