The influence of frequency of alternating or infrequently reversed current on electrolytic corrosion

Proceedings of the American Institute of Electrical Engineers (1916)

Burton McCollum G. H. Ahlborn

This paper describes experimental work done to determine the coefficient of corrosion of iron and lead in soil with varying frequencies of alternating or reversed current with 60 cycles per second as the highest frequency and a two-week period as lowest — some d-c. tests being made as a check on the methods. The results show (1), that a decrease of corrosion occurs with an increase in frequency; (2), that the corrosion is practically negligible below a five-minute period; (3), that there is, a limiting frequency above which practically no corrosion occurs; (4), that certain chemicals affect the natural and electrolytic corrosion of the two metals quite differently; (5), that the loss of lead in soil on direct current is about 25 per cent of the theoretical loss; and (6), that alternating or reversed current with as long periods as a day or a week would in the case of iron materially reduce the damage to underground structures. The importance of these results grows out of the fact that there are large areas in practically every city in which the polarity of the underground pipes reverses with periods ranging from a few seconds to an hour or more due to the shifting of railway loads. The investigation shows that the corrosion under such conditions is much less than has generally been supposed.

Electrolysis and its mitigation.

Technologic papers of the Bureau of Standards (1915)

E. B. Rosa Burton McCollum

Technical paper issued by the Bureau of Standards over studies conducted on electrolysis. As stated in the introduction, this investigation has included a study of the physical laws governing electrolytic and self-corrosion in soils, an extended investigation of the effects of electric currents on plain and reinforced concrete, and a study of the work of previous investigators relating to the subject of electrolysis and its prevention (p. 5). This paper includes tables, illustrations, and photographs.

Electrolytic corrosion of iron in soils

Proceedings of the American Institute of Electrical Engineers (1913)

Burton McCollum K. H. Logan

The paper deals with the fundamental laws governing electrolytic corrosion of iron in soils. Experimental data are given showing the effect of the different factors that are most likely to influence electrolytic corrosion of buried pipes under practical conditions, such as current density of discharge, moisture content of the soil, presence of oxygen, temperature, voltage, and other factors. The effects of earth resistance, polarization, and surface film resistances are also discussed briefly, and tables are given showing the results of specific resistance and corrosion tests on a large number of soils taken from widely scattered sources, which give an idea of the order of magnitude of the values of resistance and corrosion efficiency that may be expected under average practical conditions. A number of conclusions are presented showing briefly the effect of the different variables involved and their relation to some practical aspects of the subject of electrolysis.

ASYMMETRY OF SOUND VELOCITY IN STRATIFIED FORMATIONS

Physics (1932)

Burton McCollum F. A. Snell

In the course of explorations of subsurface geology by the seismograph the authors have frequently observed the pronounced effect of stratification on the velocity of seismic waves in shales, and this effect has often been utilized in practical seismography. Recently an opportunity was afforded for securing additional quantitative data on the velocity normal to and parallel to the bedding planes. The paper points out that the velocity parallel to the planes of stratification is, in some instances, as much as fifty percent higher than the velocity in a direction normal to the bedding planes. It is shown also that inclined stratified beds exhibit a higher apparent point-to-point velocity when sound travels in an up-dip direction than when traveling down-dip. The paper describes a procedure whereby this effect may be utilized for determining the direction and approximate magnitude of the dip in such stratified deposits. The method has proved to be of considerable practical importance where the stratified formations are obscured by overlying deposits.
