Abstract

The wear corrosion behaviour of a nitrogen ion implanted super stainless steel (S.S.S, 22Cr - 20Ni - 6Mo - 0.25N) was compared with those of S.S.S, 316L SS and TiN coated 316L SS. The Cr and Ni amounts won out from the materials were investigated using an electrothermal atomic absorption spectrometry. We observed that the Cr dissolution rate of the S.S.S was similar to that of 316L SS, however, the Ni release of the S.S.S was feater than 316L SS. The metal ions released from the nitrogen ion implanted S.S.S surface were significantly reduced. The wear corrosion behaviour of the stainless steels was not correlated with the results shown by a static metal ion release test.
