Tribological Behaviour of MnS and MnS Compounds in Friction Material for Passenger Cars 2003-01-3315
This paper explores the differences between the tribological behavior of manganese sulfide and a newly developed compound, which is a mixture of manganese sulfide and other inorganic ingredients. Eight formulation were prepared, four containing pure MnS in percentages of 15, 25, 35 & 45%; four containing the new MnS based compound with the same percentages. The base mixture contained phenolic resin, steel wool and inert substances in order not to affect the characteristics of MnS and of the new compound.
The tribological properties of the formulations like bedding, pressure sensitivity and fade were evaluated on a Krauss machine. The results showed that manganese sulfide behaved like a typical lubricant with low friction level and deep fades. The data in this paper demonstrates that admixing manganese sulfide with inorganic compounds can produce mixtures that confer good tribological properties on friction formulations. The formulations containing the new compound showed stable friction, good fade and improved material wear.
