The methods of aqueous speciation calculation. pH calculation and the solubility (precipitability) calculation of CaCO3 were used to study the mixing corrosion of CaCO3 in natural waters. Mixing processes were done between two unsaturated (with CaCO3) solutions. two oversaturated solutions and between an unsaturated solution and an oversaturated solution. https://www.roneverhart.com/GLYKON-BAYONET-BEAD-BLAST-OVERLAY-STONEWASH-STANDARD-NICKEL-BORON-INTERNALS-184-10/
