Abstract

Nanoparticles currently play an important role in reducing engine wear by using an additive in lubricant. Zirconia oxide (ZrO₂) and graphite have been used as an additive in this study. Thus, this study focuses on the investigation of wear and friction mechanism on the ball bearing tested by bio-lubricant using extreme pressure. This is due to the performance of an engine is declining because of the presence of wear in the engine part like a piston ring. The purpose of this study is to determine the suitable nanoparticle to be used in bio-lubricant as an additive. Next, the objective is to investigate of load-bearing capacity on different bio-lubricant enhanced by nanoparticles using extreme pressure method. Several testing was conducted on the extreme pressure for ball bearing lubricated by bio-lubricant and the testing accordance to ASTM D2783-Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Fluid (Four-Ball Method) for lubricant. The wear mechanism result has been compared based on different types of nanoparticles additive used in bio-lubricant that occurs on the ball bearing was investigated. Furthermore, the wear mechanism that occurs on the ball bearing was investigated by using microscope or scanning electron microscope (SEM). The result shows that with the addition of zirconia oxide and graphite nanoparticle in waste cooking oil was improved the load-carrying ability of lubricating oil. Graphite nanoparticle gives the lower coefficient of friction compared to other. Meanwhile, zirconia oxide shows a good in anti-wear additive give smaller wear rate compared to another nanoparticle. Thus, the nano-oil can give better performance especially when under extreme pressure.
