Abstract
A synchronizing ring 10 having an annular structural part 11 and a frictional layer 12 is manufactured by filling a mold 20 with a material for the structural part or a material for the frictional layer and compacting the material filled in the mold 20, filling the mold with a material for the frictional layer or a material for the structural part and compacting the material filled into the mold to unify the structural part and the frictional layer, and sintering the unified structural part 11 and frictional layer 12 in a sintering furnace. The frictional layer 12 can be combined with the structural part 11 without forcibly mounting the frictional layer 12 on the structural part 11. The material for the frictional layer need not be presintered, and the frictional layer can be formed by a single sintering cycle.
