Chemical Characterization and Tribological Behavior of Kitchen Chimney Dump Lard (KCDL) as a Bio-lubricant

Abstract

Immense study of environment friendly and renewable lubricant is now a day's major field of research for the overall sustainable development. Most of the challenges are taken towards recyclable waste to product. The Present work investigates the characterization and frictionwear behavior of Inconel 800 against 100Cr Steel applying Kitchen Chimney Dump Lard (KCDL) as a bio-lubricant. The characterization study by FTIR (Fourier Transform Infrared Spectroscopy) has shown the presence of fatty acid ester in KCDL. Tribological tests have been performed on Inconel 800 at different load and speed in a lubricated condition. From the experiment, it has been investigated that there is no such change in specific wear rate due to better lubricity property and the presence of strong bonded beneficial tribofilm on KCDL. The coefficient of friction (COF) increases with the increase in speed and load but it is less compared to waste cooking oil, and Castrol GTX 20W-50.
