主 题：Stainless steel Passive film Chromaticity inspection Sn Fe-Sn intermetallics
摘 要：The interaction between Sn and passivated stainless steel was evaluated through an easy chromaticity *** microstructure of Fe-Sn intermetallics(IMCs)was observed,and their growth was inspected at differenf time after the in teract io *** oxide film on stainless steel exposed in air locally delayed IMC growth,and the chemically passivated film protected stainless steel from Fe-Sn compound *** investigate the interaction mechanism,the integrity of passivated films grown on stainless steel was evaluated by chromogenic *** interaction extern was related to colour measurement a*.Results indicated that the measured value of a*from the inspection decreased with the increasing exposure time,and a minimum a*value was found in chemically passivated *** tendency of the colour measureme was consistent with the effect of passive film on IMC *** in terfacial reaction of passivated stainless steel with Sn was illustrated based on the integrity of the passive films.
