In order to obtain fundamental data on die castings, the mass transfer from high-Mn aluminum bronze to carbon steel in a bismuth alloy liquid metal under sliding friction has been examined. Friction tests in the molten bismuth were carried out using a pin-on-plate friction tester at temperatures of 105-205℃, at an applied load of 0.1N and a speed of 20 cm/s. Carbon steel pins with a radius of 3 mm and high-Mn aluminum bronze plates were used as samples. The main results obtained are as follows : (1) Frictional contact increases mass transfer as compared to the static contact. (2) The friction coefficient increases with increasing temperature of the molten alloy. (3) Adhesion particles on the pin and plate consist of elements from both the plate and the molten alloy. (4) Hardness of the friction surface layer of the plates gradually decreases from the interior to the surface, as a results of selective diffusion of matrix elements.
