Obdelovalnost vroče stisnjenih samomazalnih kompozitov Fe-MnS in Fe-MoS2

Šuštaršič, Borivoj (author), Kosec, Ladislav (author), Dolinšek, Slavko (author)

Poleg standardnih triboloških preskusov, s katerimi merimo koeficient trenja in obrabo drsnih stikov pod natančno določenimi pogoji preskušanja, lahko kot merilo za samomazalnost izdelanih kompozitov uporabimo tudi izmerjene velikosti rezalnih sil. Te podatke se običajno uporablja kot merilo za obdelovalne karakteristike določenega materiala. V prispevku so predstavljeni rezultati sinteze Fe-MnS in Fe-MoS2 kompozitov, izdelanih s postopkom vročega stiskanja. Njihove mikrostrukturne lastnosti so povezane z vrednostmi rezalnih sil, izmerjenih pri postopku vzdolžnega struženja.

• Title: Machinability of hot-pressed self-lubricating Fe-MnS and Fe-MoS2 composites

Abstract

In addition to the standardised tribological tests for determination of the coefficient of friction and wear at the sliding contacts under exactly defined testing conditions, the measured magnitudes of cutting forces can also be used as a measure for the self-lubrication of the composites produced. Such data are most commonly used as a measure for the machinability characteristics of a particular material. The paper presents the results of the synthesis of Fe-MnS2 composites produced with the process of hot-pressing. Their microstructural properties are related with the values of the cutting forces which were measured during the longitudinal turning process.
