LONG COLUMNAR CERAMIC PARTICLE-REINFORCED METAL MATRIX COMPOSITE WEAR-RESISTANT MATERIAL

摘要

A long columnar ceramic particle-reinforced metal matrix composite wear-resistant material, which relates to a macro ceramic particle-reinforced metal matrix composite wear-resistant material, the long columnar ceramic particle referring to a ceramic particle in which the lengthwise dimension thereof is significantly larger than the radial dimension thereof. The axis of the ceramic particle in the length direction is perpendicular to a matrix of a wear surface of a wear-resistant component, which overcomes the defect in which the ceramic particle falls prematurely from the matrix during wear resistance, increases the effective wear volume of the ceramic particle, extends the wear resistance time of the ceramic particle, fully and effectively exerts the wear resistance properties of the ceramic particle in the ceramic particle-reinforced metal matrix composite wear-resistant material, and increases the service life of the ceramic particle-reinforced metal matrix composite wear-resistant material.
