Book Description
Excerpt from Preservation of Iron and Steel by Means of Passivifying Factors: A Thesis In the tests run at room temperature potassium dichromate reduced corrosion to a marked extent in every case, in some instances preventing all chemical action upon the iron and steel. Thus tanks used for storing non-potable waters at atmospheric temperatures could be well preserved by the addition of small quantities of potassium dichromate. However, with waters in boilers the addition of this compound will, in many cases, serve as a stimulative agent rather than as a preventive for corrosion. This will be seen by studying the data obtained when the iron and steel were placed in solutions free from dichromate at boiling temperature for two weeks and comparing them with the results from those boiled in solutions in which this salt was present. In many of the solutions the presence of the dichromate was occasioned by a slight increase in corrosion. This was especially true in the chloride solutions. In fact, from the general appearances of the test plates, this increase in corrosion seemed greater than that actually repre sented by the following figures. Plates of the iron and steel were introduced into distilled water and subjected to the same treatment as accorded to the samples in the various 'solutions. At the end of two weeks the plates were removed, dried, and weighed. The plates were all slightly tarnished. The gain in weight of the plates served as a standard for calculating the relative corrosion. The test-plates immersed in the salt solutions free from dichromate corroded to a certain extent, a small brown precipitate settling on the bottom of the containing vessel. It was thus impossible to weigh the plates directly and determine the rate of corrosion by gain in weight. The plates, however, were very easily cleaned with ammonium citrate and the loss in weight determined. The equivalent amount of ferric oxide represented by the loss in weight was calculated. While this does not accurately represent the actual amount of corrosive matter produced it is fairly approximate, so that it can be reasonably compared with the data obtained from plates where cleaning was impossible.
