In situ monitoring of corrosion processes by coupled micro-XRF/micro-XRD mapping to understand the degradation mechanisms of reinforcing bars in hydraulic binders from historic monuments
In situ analyses under synchrotron XRD have highlighted the corrosion processes of a rebar embedded in concrete in the presence of chloride.
In situ time-lapse synchrotron radiation X-ray diffraction of silver corrosion
In order to study the initial corrosion processes of silver in the presence of corrosive gases in situ time-lapse XRD experiments were performed. The data collected using a newly combined environmental cell/gas flow set up introduces a set of highly useful tools for scientists to study time-lapse gaseous corrosion at ambient temperature and pressure.
