“…Liquid lead-bismuth metal is the primary coolant for an improved liquid metal nuclear reactor [9]. The paper [10] presents the results of a study of the friction of the bearings of the main circulation pumps. The paper [11] considers the issues of modern technology of lubrication under extreme pressure, using the high thermal diffusivity of liquid metal.…”

The article presents the results of tribological tests of a thrust bearing made of steel-bronze materials when lubricated with a lead-bismuth metal melt under conditions of heating up to 500°C. The influence of steel-bronze on the coefficient of friction in the ranges of load 0.17–1.0 MPa, velocity 0.05–0.23 m/s, and temperature 250–500°C was studied. It has been established that the tribological properties of friction pairs under experimental conditions mainly depend on temperature, which determines the wetting angle and the viscosity of the metal melt. With an increase in the temperature of the melt above 300°C, the viscosity of the melt decreases, and the liquid metal lubricant is squeezed out of the actual contact areas.
