In order to study the tribological properties of different hydraulic oils under different motion modes, four-ball tester and block-on-ring tester were used to optimize the test parameters and evaluate performance of commercial hydraulic oils. The results showed that the optimized test methods under the form of point and line motion modes can better evaluate the extreme pressure and anti-wear performance of hydraulic oi. There was a negatively correlation between extreme pressure and anti-wear performance; this method can provide a basis for the reasonable selection of lubricating oil in hydraulic system.

AbstractThis investigation reports on the effect of Pongamia oil doped with lube oil on tribological characteristics of Al-7% Si alloy using the Taguchi method. The control factors involved were Pongamia oil percentage (PB 0%, PB 15%, PB 30%), sliding velocity (1.3 m/s, 2.5 m/s, 3.8 m/s) and load (50 N, 100 N, 150 N) which was optimized for weight loss, friction coefficient and wear rate characteristics of Al-7% Si alloy. The conventional lubricant SAE 40 was used for the experiment and for contamination. In this study, L

Friction And Wear Tests

In this study, the tribological behavior of lamellar MoO3 as a lubricant additive was investigated under different concentrations, particle sizes, normal loads, velocity, and temperature. The friction and wear tests were performed using a tribometer and with a reciprocating motion. The results indicate that the friction-reducing ability and antiwear property of the base oil can be improved effectively with the addition of lamellar MoO3. The 0.5 wt % and 0.1 wt % concentrations of MoO3 yield the best antifriction and antiwear effects, respectively. The maximum friction and wear reduction is 19.8% and 55.9%, compared with that of the base oil. It is also found the MoO3 additive can decrease the friction considerably under a high velocity and normal load, and increase the working temperature. The smaller the size of MoO3, the better the friction-reducing effect the lamellar MoO3 shows. The friction-reducing and antiwear mechanisms of lamellar MoO3 were discussed.
