| Abstract: | The crevice corrosion behaviour of CuZnAl shape memory alloy in saline solution has been investigated with immersion test and electrochemical measurement techniques. The results show that corrosion rate of crevice specimen is higher than that of the free surface specimen. The corrosion potential of crevice specimen is less noble than that of the free surface specimen by 30 mV, which confirms that crevice corrosion is the more easily occurring type even in Cu based memory alloy. |
