Graphite ring is formed by pressure with flexible graphite sheet cut into fixed size and being intertwined and pressed into a special mould. It keeps all the characteristics of flexible graphite. suitable for valve and pump in a condition of violent changement in temperature and pressure.

To make the graphite product apply and perform excellent wear resistance and self-lubrication property in the circumstance of high temperature and heavy pressure,the graphite/antimony composites were prepared by forcing the melted antimony into pores in the graphite preform with mechanical pressure infiltration method.The microstructure,friction and wear behaviour of graphite preform and graphite/antimony composites were studied,and the change on the friction and wear behaviour after infiltration was estima...
