<P>PROBLEM TO BE SOLVED: To further improve the wear resistance of a compound wear resistant material dispersed with high-hardness carbide particles in a matrix metal. <P>SOLUTION: The high-hardness variant carbide particles 20 are dispersed and mixed into the matrix metal 10 in such a manner that a sectional ratio of 20 to 70% is attained. The high-hardness variant carbide particles 20 have holding sections 22 projected from a part of the surface of main parts 21 so as to bite into the matrix metal 10 in order to suppress the elimination of the particles from the matrix metal 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
