Traction Behavior for Rolling Bearing based Solid Lubrication under the Cryogenic Environment

Abstract

Cryogenic applications have the harsh conditions such as the heavily load, high speed and cryogenic fluids conditions. Silver (Ag) and PTFE used in aerospace applications have shown the reasonable low friction and wear. The reason why we should pin-on-disk test is to prove the effect on the solid lubrication under the cryogenic environment. Through this experiment performed friction test with the cryogenic fluid, it came out the relationship the traction behavior with interacting in coated bearing components. This paper will discuss the following: space mechanism components, solid lubrication, and factors affecting wear phenomenon.
