As the key connecting, driving and slewing supporting base parts, the rings had many varieties, large dosage and wide application. In extreme harsh environments such as deep space exploration, petrochemical and wind power, different requirements were put forward for the inner and outer performance of the ring, and it was increasingly difficult for the single metal ring to meet the actual performance requirements. Bimetallic composite ring can combine the advantages of two kinds of single metal materials at the same time, maximize the complementary advantages of their properties, and improve the service performance and reliability of the ring. The present situation of manufacturing technology of bimetallic composite ring members was reviewed, and according to the different interface bonding mechanisms of composite ring members, the bonding laws and characteristics of mechanical bonding methods such as rolling, expanding, drawing and drawing, and metallurgical bonding methods such as centrifugal casting, etc., were emphatically expounded. The limitations and existing problems of the existing manufacturing technology were pointed out. Based on the centrifugal casting complex method, the short process manufacturing technology of bimetal composite ring based on centrifugal casting billet was proposed. The characteristics, research content and development trend of the new technology were summarized.
