The sliding surface member (2) is brought into close contact with the front and back surfaces of the peripheral portion of (1).
It is set and heated to a semi-melting temperature range of one or both of the members (1) and (2) by a high frequency induction heating furnace or the like, and is maintained at that temperature. At this time, in order to prevent oxidation of the joining surface of both members, it is preferable to heat in a vacuum furnace or an atmosphere furnace,
Since it is not advantageous from the point of practicality, as a simple method, a brazing flux is applied to the outer peripheral portion of the joining surface of both members as shown in FIG.
It is effective to apply (3).

Next, the two members were combined, a brazing flux (3) was applied to the outer peripheral portion of the joining surface of the two members, and this was heated and maintained in a high-frequency induction heating furnace at a semi-melting temperature of both members. Thereafter, the above combined product was placed in a preheated mold (4), pressed, and joined. Thereafter, annealing and machining were performed to obtain a product. Although the friction characteristics of the thus obtained disk rotor of the present invention are as good as those of the conventional FC-integrated rotor, the rotor strength is about twice as high. Furthermore, the condition of the joint surface is good, and the joint strength is 19.7 on average.
