Document Type and Number:
Japanese Patent JP2863768
Kind Code:
B2
Abstract:
PURPOSE: To prepare simply a shattering face member on the surface layer part of which a block with a low wear resistance and a block with a high wear resistance are alternatively arranged.
CONSTITUTION: The surface layer part is formed out of a matrix metal 1 with a low wear resistance. Channels 2 are provided on the surface of the matrix metal 1. A wear-resistant metal 3 is filled as one layer in each channel 2 by casting. Shrinkage caused by solidification of the wear-resistant metal 3 is absorbed by deformation of walls 4 and 4 on the both sides of the channel 2.
