The focus of this paper is the in-situ assessment of calcium carbonate formation on a stainless steel surface. Calcium carbonate formation is studied by Synchrotron X-Ray Diffraction (SXRD) with a flow cell that allows in-situ and real-time measurements. The effects of a commercial scale inhibitor, Polyphosphinocarboxylic acid (PPCA) on formation is also studied. Previously silicon was used as the substrate for SXRD measurements and therefore the effects of the substrate nature on calcium carbonate formation and its inhibition by PPCA are discussed. ©2008 by NACE International.
