In the manufacturing of Kelmet, i.e., the bearing metal which is made by casting the Cu-Pb alloy on to the extra low carbon steel cylinder as the back metal, the alloy contacts with the back metal for a considerable period, in the consequence of which some quantity of iron will be dissolved into the alloy. But when the quantity of the iron increases above the limit, which is specified at 0.80%, hard particles will form in the structure of the alloy and thereby the abrasion of the shaft increases. Therefore, the determination of the dissolving velocity constant of iron into the alloy at the manufacturing temperature of the bearing metal is of vital importance. From the foregoing reason, the present investigation was carried out to determine firstly, the dissolving velocity constant of iron into copper, secondly, into copper-lead alloys. The general conclusions from the results of the experiments are as follows: (1) When the molten copper or copper-lead alloy at high temperature contacts with the solid iron, the iron is dissolved into the copper or copper-lead alloy and the dissolved iron diffuses very rapidly through the molten copper or copper-lead alloy, the phenomenon being similar to the case when the iron is dissolved into the alloy by stirring violently. Thus the iron is distributed almost homogeneously in all parts of the alloy. (2) In this experiment, therefore, copper or the copper-lead alloy was melted at some constant temperature in the Tammann tube, into which the iron rod was immersed, allowing the iron to dissolve and diffuse. From the quantity of the dissolved iron, the dissolving velocity constants of iron into copper and the copper-lead alloy were determined. However, in order to obtain definite results, as many experiments as possible were made, i.e., varying the quantity of the copper or copper-lead alloy, the diameter of the iron rod and the dissolving time. The following formula was adopted for calculation. [numerical formula] (3) From the calculation results the following values were obtained as the dissolving velocity constants.
