Abstract: This paper presents the
results of investigation on the characteristic of forming EHL
film by oil-in-water emulsions in point contact condition. The
emulsions of diverse proportion and concentration have been
prepared by mixing the surfactants and additives with machine
oil No.30. The experiment of lubricating properties of the
emulsions has been measured on a Optical Interference EHL
Tester. The results show that a full EHL film can be formed for
the developed emulsions. The ability of forming film is affected
by the proportion of emulsifier to base oil. The concentration
of base oil and temperature have stronger effect than load on
lubricating film. The investigation proved also that the
emulsions show similar lubricating properties to the base oil in
starved conditions.
