2012/8/11· Silicon carbide in its best configuration is still somewhat fragile and sensitive to chipping. Several drive mechanisms have been developed that provide a soft drive with the silicon carbide rotor rather than jamming it against a hard metal drive pin. Figure 13-75

Friction and wear behavior of different seal materials …

The shaft mechanical face seal in a high-speed turbopump of a liquid rocket engine often operates under extremely harsh conditions. For example, a low-temperature and low-viscosity fluid (such as liquid oxygen or liquid hydrogen) is used as a lubricant. The performance of the seal rings, especially the friction and wear behavior, directly determines whether the seal functions normal. In this

Modern Mechanical Carbon Materials for Aircraft Seal …

The face seals usually contain a carbon-graphite stationary ring and a silicon carbide or tungsten carbide rotating ring. The rings that make the dynamic face seal are both lapped flat and are held together with springs or magnets so that liquids cannot flow between the ring faces even though they are spinning against each other at high speed.
