  • Bucket teeth having a metallurgically bonded coating and methods of making bucket teeth
    Patent number: 9003681
    Abstract: Bucket teeth having a metallurgically bonded wear-resistant coating and methods for forming the coated bucket teeth are disclosed. The bodies of the bucket teeth have a hard metal alloy slurry disposed on a surface and then are fused to form a metallurgical bond with the iron-based alloy. The wear-resistant coating can be formed of a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof. The portion of the outer surface of the bucket teeth having the wear-resistant coating corresponds to a wear surface of the bucket teeth during operation.
