| Description |
The performance of additive molecule is gover-ned by its
chemical structure as wel~ as the type of elements present in
it. Tho ugh, S E\.e ,- a 1 i n v est i gat Ion S h a \,. e been con due t e d t hE'

study was undertaken on the perfQrmance behavior of additives
containing sulphut-, phosphot-ous' as actIve elements having
differ-ent chemicCtl structut-es. It is obset-ved that even
though the sulphut- level i~. the sarne for different additives
in the blends, their perfOt'mance differed markedly, cleat-ly
indicating the.t the chemical structure of the additive

contact stresses, film thIcknesses etc. to render an
effective discrimination of performance results of the
additives. The additives were evaluated by 4-Ball extreme
pressure (EP) testing machine as we11 as by shoc k load test
developed at authors laboratory for evaluation of shock load
tendency of gear oils using Amsler friction and wear machine.
This paper discusses the effect of dose-response relationship
of different chemical structures employed in the oil system.
It is seen that the chemical structut-e of the additives
governs the tribological J2ehavior greatly and controls the
failure phenomenon.
