AN EVALUATION OF THE STATE OF BOTTOMS OF RAILS DAMAGED BY CORROSION

OTSENKA SOSTOYANIYA PODOSHVY REL'SOV, PORAZHENNYKH KORROZIYEY

The inaccessibility of locations where corrosion frequently occurs in rails, such as the underside of the tie plate, is a major limitation to means for detecting it. This is particularly a problem where ties of pressed wood are in use. The authors of this brief paper propose a method for corrosion detection which involves the use of an ultrasonic defectoscope which indicates the depth of the corrosion present by the strength of the signal emitted. The progression of corrosion from cavity to fracture is documented, and descriptions of their experiments with the defectoscope comprise the bulk of the article.
