INFLUENCE OF PHASE COMPOSITION ON PITTING CORROSION RESISTANCE OF SPUTTERED LAYER OF 1Cr18Ni9Ti STAINLESS STEEL
相组成对1Cr18Ni9Ti微晶溅射层耐孔蚀性能的影响

A series of single bcc, bcc plus fcc duplex and single fcc microcry-stalline Coatings of 1Cr18Ni9Ti stainless steel were prepared by using sputteringtechnique. The resistance against pitting corrosion was studied by measurements ofpitting corrosion potential and electrochemical noise during the initiation of corro-sion pits. The results show that the sputtered layers with single phase bcc or fccstructure are more resistance to pitting corrosion than those with bcc plus fcc duplexphase structure.
