ABSTRACT:
A coating (22) with a high coefficient of friction and low thermal conductivity covers a turbomachine low pressure shaft (12) in the vicinity (17) of a concentric high pressure shaft (11), in the area at which high friction contact between the two shafts could occur if a bearing (13) on the low pressure shaft (12) breaks following a failure causing the appearance of an out-of-balance mass. Friction would also more quickly equalize shaft speeds and reduce overheating in them.
