摘要

This paper reports on the characterisation of ceramic matrix composites (CMCs) for bearing applications in liquid oxygen (LOX). Compatibility tests were performed to determine the safety and feasibility of subsequent research operations. Tribological tests were then made on a pin-on-disc apparatus using LOX as the working environment. The measurement of friction and wear allowed a comparison between different kinds of CMCs and 440C steel materials. As a logical progression a real geometry test rig is now being built. The design of a hybrid journal bearing has been finished and the manufacturing of the rig components started.
