| description | The fishscaling resistance of enameled steel is closely related to the hydrogen-related behaviour of its constituent phases, in which dispersed co-precipitates are regarded as the most effective hydrogen-trapping sites. To investigate the respective roles of the individual precipitates on the hydrogen trapping ability and locations in enameled steels containing a co-precipitate, in situ Scanning Electron Microscopy (SEM), correlated with Scanning Kelvin Probe Force Microcopy (SKPFM), was employed in this work. Chemical analysis from Energy Dispersive Spectrometer (EDS) mapping showed that the co-precipitate was composed of four precipitates, namely Ti4C2S2, Ti(C,N), TiN, and Al2O3. Changes in surface micro-potentials before and after hydrogen charging were measured for each single precipitate using SKPFM technology. There existed a significant difference in the potential change between the four composite precipitates, which could distinctly reflect the difference in hydrogen trapping abilities and fishscaling resistance. The results showed that the hydrogen trapping abilities of the four precipitates were in the following order: Ti(C,N)[Formula: see text]Al2O3[Formula: see text]Ti4C2S2[Formula: see text]TiN. Furthermore, a peak analysis of the potential demonstrated that the hydrogen atoms were mainly trapped in the interface zone of the Ti4C2S2 and TiN precipitates, while the dominant hydrogen trapping locations of Ti(C,N) and Al2O3 precipitates were primarily the centre area of the particles. |
