Application of Corrosion Resisting Materials to Railroad Electrical Construction. H. F. Brown. Corrosion, 6, No. 8, 268-273 (1950) Aug.
Discussion by H. P. Godard, Aluminum Laboratories, Ltd., Kingston, Ont., Canada:
From the introduction and abstract of the paper “Application of Corrosion Resisting Materials to Railroad Electrical Construction” it is implied that the main purpose of the tests was to determine the corrosion behavior of a large number of materials in the smoky atmospheres along a steam railroad right-of-way. One of these materials was aluminum, in the form of bar specimens, trolley clips and stranded cable. I would point out, however, that the manner in which the aluminum specimens were suspended caused an appreciable amount of galvanic corrosion and contributed materially to their unfavorable performance. The results, therefore, do not fairly represent the behavior of aluminum in the atmosphere described.
