Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.

Example 1

As shown in fig. 1 to 4, the embodiment provides a high wear-resistant inlaid casting, which includes a circular hammer disk 1, a plurality of stud layers 2 are uniformly inlaid and cast on the side surface of the hammer disk 1 along the axial direction, and each stud layer 2 includes a plurality of studs 5 arranged at intervals; the studs 5 are hexagonal prisms, parts of the studs extend out of the hammer disc 1, and the studs 5 between the adjacent stud layers 2 are arranged in a staggered mode.
