Title:
COMPOSITE WEAR RESISTANT MEMBER
Document Type and Number:
Japanese Patent JP3707070
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve problems such as dispersion in the grain size of a product and a lowering of crushing efficiency heretofore unavoidable due to uneven wear from the functional point of view of a device, even in a composite wear resistant material formed of two materials.
SOLUTION: A wear curve M in a worn surface when the wear resistant member formed of only the material A forming a base material 1 reaches the limit of service, is empirically grasped, and the filling rate of a filler 2 which is a higher wear resistant material, is set every worn surface divided according to the wear resistance ratio of the material B to the material A. The worn surface in service thereby recedes uniformly over the whole surface while forming a nearly straight wear line H, thus solving the problems.
