抄録

It is well known that the electrolytic isolation method has rendered a considerable service to the metallographic researches on carbides, oxides and other constituens in iron and steel. The present study was designed to establish the electrolytic conditions for the isolation of sulfides from low-carbon alloy steels using sodium citrate cells and hydrochloric acid cells, and to carry out some preliminary experiments by this procedure. The results obtained are as follows: (1) The sodium citrate cell with an electrolyte of 15% sodium citrate+1% potassium bromide solution is applicable to the isolation of almost every kinds of sulfides, except CrS and Al2S3. (2) The 0.5 N hydrochloric acid cell is applicable to the isolation of VS, ZrS, TiS, NbS and CrS with satisfactory results. (3) The microphotographs of various sulfides isolated from the steels show the charactaristic shapes, which provide new informations on the three dimensional structure of sulfides.
