Document Type and Number:

WIPO Patent Application WO/2007/114524

Kind Code:

A1

Abstract:

Disclosed is a wear-resistant particle which can be substantially uniformly dispersed in a molten pool. Specifically disclosed is a wear-resistant particle (13) which is dispersed in a matrix metal for improving wear resistance thereof. The wear-resistant particle is characterized by being composed of a material containing a first hard material and a second hard material while having a particle diameter of 0.2-9 mm. The wear-resistant particle is further characterized in that the material consists of 60-96% by volume of a carbide and the balance of a metal.
