  • METHOD FOR PRODUCING BRAKE DRUM AND A BRAKE DRUM
    Publication number: 20140034433
    Abstract: The present invention discloses a method for producing brake drum, wherein three different metallic materials are used for the three-layer construction; and two layers made of different molten metallic materials are cast based upon the prefabricated steel shell (with steel or gray iron for the structural layer and the Mo-containing, abrasion-resistant alloy cast iron for the braking friction layer) so that atoms from these two adjacent but different metallic layers inter-diffuse across the interface to form a solid fusant or an inter-metallic compound, thereby generating a very strong metallurgical bond. The present invention also provides a brake drum, comprising a brake drum shell, a structural layer inside the brake drum shell, and a friction layer inside the brake drum structural layer and for braking.
