Abstract
A composite article (e.g., prosthesis) and method of preparing the article is provided. An article may include a body having a matrix of a first hardness having a plurality of particles of a second hardness embedded in the matrix in fixed locations, the second hardness being harder than the first hardness, and the matrix having an external wear surface with a portion of the particles being proximal to or exposed at the external wear surface. The matrix with the particles may improve the life and durability of the article.
