A synchronizing ring assembly (1) comprises at least two synchronizing rings (2, 3, 4). The latter each have a frictional surface (7, 8; 15, 16) which can be placed into operative connection to one another to form a friction pairing. At least one of the two synchronizing rings is manufactured from a steel material and the other from a brass material. The brass-material synchronizing ring has a structure in which harder particles P are incorporated into a softer crystalline base material. The frictional surface (8, 15) of the friction pairing of the steel-material synchronizing ring (3), which frictional surface is complementary to the other frictional surface, is formed by a friction lining (13, 14) consisting of an organic binder with filler particles incorporated therein, wherein the filler particles are harder than the binder. A method for forming the friction linings of a synchronizing ring (3) having two friction linings (13, 14) arranged concentrically with respect to each other is defined in that use is made of an injection-mouldable and/or transfer-mouldable plastics compound and the latter is applied by means of a plastics injection-moulding or transfer-moulding method from one side of the ring section (9) which is to be coated, and the friction lining compound is guided through apertures (11, 12) in the ring section (9) from the casting side onto the ring section surfaces which are provided for forming the frictional surfaces (13, 14).

Abrégé

A description is given of a method for the heat treatment of a workpiece produced from a titanium alloy for obtaining a fine-grained microstructure by annealing the same above its β-transus temperature Tβ. According to the invention, the workpiece is heated in a furnace to a temperature level TH above its β-transus temperature Tβ. Reaching the temperature level TH determines the beginning of a predefined holding time, for which the workpiece is kept at this temperature level TH. The workpiece subsequently undergoes a cooling process. To carry out the heat treatment, the furnace temperature TF is set such that, for heating up the workpiece to the temperature level intended for carrying out the holding, it lies above the temperature level TH of the workpiece determining the beginning of the holding time.
