Nano coat as an effective replacement for bearing liner

Abstract

This work highlights an experimental investigation on the surface roughness and hardness of a nano composite, which can replace the liner of a journal bearing. There is a possibility of rotation of bearing liner, due to inconsistent rotation of the journal about its geometrical axis. At the same time, the liner may have sliding action inside the bearing over a period of time. The said drawbacks can be eliminated by replacing the bearing liner by a nano coat. Babbitt is the most widely used material for bearing liner. The Tin of Babbitt alloy has been replaced by cadmium due to its low coat and better mechanical and thermal properties. The results show that, Cadmium is offering better surface roughness and hardness in comparison with the Babbitt.
