The Properties of Babbitt Bushes in Steam Turbine Sliding Bearings

Abstract

The Properties of Babbitt Bushes in Steam Turbine Sliding Bearings The analysis of the properties of babbitt bushes is presented in this article. Materials intended for examinations were charged from the TK-120 steam turbine of TG-8 turbosystem from the Power Station Stalowa Wola. The specimens were subsequently tested for Brinell hardness, microhardness, bending strength and wear resistance. The wear tests were carried out using the block-on-ring tester. The samples were also investigated by means of both light microscopy (LM) and scanning electron microscopy (SEM).
