The tribological performance of modified RBD palm kernel oil under extreme pressure load test

Abstract

Lubrication is one of the most used components globally in various types of applications. The hiking in demand of lubrication oil annually rise several issues such as environmental wastage and oil supply. This paper discussed the alternate option of lubricant oil performance from renewable resources that helps to preserve the environment and support the current mineral oil supply. Refined Bleach and Deodorised Palm Kernel Oil was used in this research as tested lubricant undergone normal load test (ASTM D4712) and extreme pressure (ASTM D2783) according to the ASTM test standards. The Refined Bleach and Deodorised Palm Kernel Oil was tested at two conditions of semi-solid form and liquid form. A liquid form of Refined Bleach and Deodorised Palm Kernel Oil was synthesized with transesterification process to convert the semi-solid form into liquid at room temperature. Results shows that Refined Bleach and Deodorised Palm Kernel Oil performance was comparable to the fully synthetic oil in terms of COF, WSD, and surface roughness while in the extreme pressure test shows that ISL of palm-based oil are slightly lower than fully synthetic oil by 127N.
