Abstract
The aim of the experiment is to investigate the tribological behavior of Brass
and tin-based babbitt materials. The experiment is conducted on a pin-on-disk wear test
machine at room temperature to analyze their effect on tribological behavior. The
experiment is conducted at various operating factors like load, sliding time and sliding
velocity under dry and lubrication conditions. Application of these materials is mostly
found in automobile bearing, precise instrument, railway bearing, aerospace and heavy
duty application. After conducting the experiment, it was noticed that tribological
behavior slightly changes at elevated temperatures. The use of oil lubricant improves
the tribological performance as compared to dry conditions by 18.56 times for tin-based babbitt alloy and by 2.19 times for brass material. Thus the performance of Brass
under oil lubrication is superior to tin-based Babbitt due to its hardness. Under dry
conditions, the wear rate of brass material is approximately four times that of wear in
tin-based Babbitt; thus, the service life of tin-based Babbitt is longer than brass
material under dry conditions.
