ABSTRACT:
The invention concerns bronze-based sintered contact components for use as slide components such as clutches and brakes and is intended to provide a sintered component comprising hard particles admixed with and finely and uniformly distributed in a Cu-Sn alloy matrix to provide improved friction coefficient, and in which the dispersed hard particles are inhibited from coming off the Cu-Sn alloy matrix during contact movement so that the sintered component is possessed of good friction contact characteristics and improved mechanical properties. A sintered contact component comprising Sn, and iron-based intermetallic compound as a hard particle ingredient, and a solid lubricating ingredient which have been passed through the process of mechanical alloying, mechanical grinding or pelletizing, the Sn, iron-based intermetallic compound, and solid lubricating ingredient being uniformly dispersed in a Cu matrix.
