Abstract

A four ball wear test was designed and tested with a series of petroleum based hydraulic fluids. This test procedure comprises a sequence of three 30 minute test segments designed to evaluate 'wear in' steady state wear and the effect of antiwear films produced in the first two parts of the test. A series of formulated mineral oil base lubricants that have been evaluated extensively in heavy duty industrial hydraulic equipment were also evaluated in a laboratory pump test system and the sequential four ball wear test. A correlation developed for the heavy duty industrial hydraulic systems with the laboratory pump test system was extended to the four ball wear tester sequential runs under specific load and temperatures.
