Abstract:
Trapped air in lubricants can negatively impact machinery performance, leading to inefficiencies, cavitation, and increased wear. To address this issue, standardized tribological testing methods have been developed to assess the air-release properties of lubricants under controlled conditions. This poster presents recent advancements in air release evaluation in accordance with ASTM D3427, a recognized method for determining the time required for dispersed air to separate from oil under specific temperature and pressure conditions. The study focuses on hydrocarbon-based lubricants, with particular attention to bio-based formulations such as epoxidized Karanja oil. Comparative analysis reveals that epoxidized oils exhibit significantly improved air release times when benchmarked against conventional base oils. These findings highlight the potential of functionalized bio-lubricants to enhance performance while supporting sustainability goals. By integrating standardized test protocols with advanced measurement techniques, researchers can gain deeper insights into lubricant behavior, enabling the development of formulations that improve system reliability, reduce operational risk, and extend machinery lifespan.
