Early work1 depicts two distinct effects resulting from corrosion of metallic substrates on the deposition of water-formed scales:
Recent work2 has identified SrCO3 in actual scale samples from a wet producing well. The scale was predominantly CaCO3. EPMA analysis of the scale samples showed that in the CaCO3 scale, there were rod-like particles that contained SrCO3 up to 15 wt%. This stimulated us to study SrCO3 deposition in the laboratory.
The current paper presents the results of experiments designed to deposit SrCO3 crystals on substrates of carbon steel in order to examine if the corrosion reactions influence in any way the nucleation and growth of the scaling crystals in the initial stages of deposition.
Solutions were prepared from reagent-grade chemicals and doubly distilled water. Substrate specimens of 1 by 1 cm size were prepared from C1020 (UNS(1) G1020) plain carbon...
