Quarterly Report of the Solution Corrosion Group for the Period Ending April 30, 1958

“…Among the alloys tested were a group of austenitic stainless steels, a ferritic stainless steel, and several high-nickel content alloys. The results of the tests appear in Table VI. Initial results have been reported (19) previously.…”

“…The loop containing the circulating solution described in section (2) :.' above was cooled from 300 to 225'C at the end of the solution stability test, and the hydroclone was isolated by freezing an ice plug in the inlet line.…”

“…It (8) may have been that in repositioning the reinforcing rings after the fifth test the clearance between the rings and the bellows was increased. An increase in clearance would have allowed flow of solution between the rings and the bellows thereby preventing a concentration cell type of pitting.…”

The Oxidation of Chromium(iii) to Chromium(vi) in the Presence of Platinum Metals

“…1 Since Cr(Vl) is a corrosion inhibitor in many environments, it was of interest to see if ruthenium or other platinum metals would catalyze the oxidation of Cr(lll) to Cr(Vl) in several different environments.…”

Summary of Runs D-77 Through D-93. Rate of Oxidation of Chromium(iii) in Dilute Uranyl Sulfate Solution in the Presence of Ruthenium

“…Images are produced from the best available original document. (1,2,3) inhibits the corrosion attack of stainless steel exposed in the solutions.…”
