。In addition, in synchronizer rings using ceramic materials,! It is estimated that the manufacturing process itself is complicated and expensive. For example, a synchronizer ring with a ceramic material was manufactured using a conventional sintering method in which -8 sintered ceramics was inserted into a mold for a synchronizer ring in the form of segments, and a sintered steel member was first manufactured. In this case, deformation may naturally occur due to the difference in thermal expansion coefficient between the materials during sintering. At this time, a machining process is naturally required to correct this. Especially synchronizers made of ceramic segments.
Since the inner surface of the ring becomes a frictional coupling surface, mechanical processing is required, which is accompanied by the difficulty of machining ceramics.
