Vegetable oils are sustainable fluids which have been promoted to replace petroleum-based oils due to its environment friendly characteristics; it is being a very important supply of biolubricant. The excellent advantage of vegetable oil is the fact it is really which can be used environment friendly supplier. In addition, vegetable oil based lubricant clearly show the possibility to minimize carbon monoxide also hydrocarbon emissions when used in IC engines. There are basically two different ways to using vegetable oil to be a bio-lubricant, either one by directly use the pure vegetable oil with additives or use certain blending ratio of vegetable oil with mineral lubricant. In this paper, the influences of the blending ratio of mineral oil with RBD palm olein on the tribological characteristics were investigated and compared with commercial lubricant oil by using the four ball tribotester. The blending ratio was varied from neat with interval of 20% by volume. All experimental works were conforming to ASTM D4172. The results exhibited that the blend of RBD palm olein with commercial lubricant oil has lower the wear scar of ball bearings and coefficient of friction compared to commercial lubricant oil. As a conclusion, the blending of RBD palm olein with commercial lubricant oil has better performance compared to commercial lubricant oil or pure RBD palm olein.

In this study, the effect of load on the tribological performance of RBD palm olein is investigated using a four-ball wear tester according to the standard test of ASTM D4172. Tests were conducted with 40, 60, 80, 100 and 120 kg normal loads. The experimental temperature and rotational speed were held constant at 75 °C and 1200 rpm, respectively. The test duration was 60 minutes in all cases. For each load, the tribological properties of RBD palm olein were compared with the properties of additive-free paraffinic mineral oil. The results focused on the frictional torque, wear scar diameter, friction coefficient and the flash temperature. Following the completion of the wear test experiments, the ball wear condition and lubricant properties were observed. These results show that RBD palm olein has a lower coefficient of friction than paraffinic mineral oil; however showed a high oxidation effect under high temperature work conditions.

Sustainable manufacturing has become popular among manufacturers and industrialists due to the increase in environmental issues, health impacts and stringent law enforcement. The use of vegetable oils as metalworking fluids is one way to implement manufacturing sustainability. Palm oils are commonly used as cooking oils. Further, palm oil is also the main oil sources in Southeast Asia besides petroleum. Therefore, the potential use of palm oil as functional lubricant for future replacement of petroleum-based oil is indeed important. In this study, the refined, bleached and deodorized (RBD) palm olein has been formulated into various properties of modified RBD palm oil (MRPO) by transesterification process at different molar ratio of RBD methyl ester (FAME) with trimethylolpropane (TMP). Next, the MRPOs are compared with synthetic ester on lubrication and tribology tests according to standard based on American Society for Testing and Materials (ASTM). The results observed that MRPO have outstanding performance in lubrication and tribological behavior. MRPO2 recorded the highest viscosity index and the lowest coefficient of friction which are 496 and 0.06, respectively. MRPO2 showed to be an alternative biodegradable cutting fluid in promoting sustainable manufacturing activities by reducing the bad impact on environment and health.

In this paper, the effect of sliding speed on the anti-friction of RBD palm olein was investigated using four-ball tribotester. The speeds were varied from 800 to 1400 rpm. The normal load was set to 40 kg and the test oil was heated up to 75 °C before the experiments. The result showed that palm olein has low friction coefficient compared to additive-free paraffinic mineral oil.
