Abstract

This paper presents an experimental investigation of the tribological behavior of four brass alloys’ synthesis by forging (Mm), free-cutting (Md), gravitational casting (Mc), and casting under pressure (Mi). The experiments were conducted on a pin-on-disk tribometer with a load of 200 N, sliding speed of 2.5 m/s, and a sliding distance of 500 m. The microstructure and the worn surfaces were examined with an optical and scanning electron microscope. The results obtained show that the Mc material has less wear resistance related to the presence of voids and an abrasive wear mechanism and the Md material has a stabilized friction coefficient which is related to the uniform distribution of the various phases in the microstructure and the presence of a thick layer of metal transfer on the counter material.
