Abstract

Hexagonal boron nitride (h-BN) has a graphite-like lamellar structure and has been used as oil additive for the study of self-lubricated porous sliding bearings. The present paper is based on a series of experimental studies with h-BN as an additive and discusses results in the form of performance characteristics like the coefficient of friction, bearing temperature, pressure distribution, load carrying capacity etc. The tribological properties were compared with the conventional sliding bearings. The results of the experimental studies showed that h-BN as an additive in transformer and hydrorafined-5 oil possesses good friction reducing, high load-carrying capacity and excellent anti-wear properties.
