Lu Feng. Effect of the GECM Surface Protection on Galvanic Corrosion of LY12CZ Aluminum Alloy[J]. Journal of Materials Engineering, 1996, 0(12): 28-30.
The effect of GECM with different surface treatment on the galvanic corrosion of LY12CZ alloy was investigated by applying electrochemical measurement,ASTM 5%salt spray test,alternate immersion corrosion test and atmospheric exposure.The open circuit potential by electrochemical measurement shows a relatively large potential difference of approximately 1V between the GECM and LY12CZ alloy,GECM/LY12CZ couple galvanic corrosion can take place,corrosion current data(Zero Impendance Technique)indicates that there is a serious corrosion problem at GECM/LY12CZ couple.In order to prevent galvanic corrosion,graphite and LY12CZ can not be directly contacted,GECM surface should covered with glass cloth,sealed edge,and painted.Some protection methods,such as anoding and painting,should be also taken for LY12CZ.
