Abstract: A self-lubricating composite material with refractory metal tentalum matrix developed by hot pressing and sintering process in powder matallurgy and its application are presented. The friction and wear behaviors of the material in air and the structure analysis for the lubricating phase of the material are discussed. The life of rolling bearings with cages made of this material was tested in high vacuum condition and the results of the tests showed that the cages had satisfactory performance and efficient Lubrication for the bearings.
