Abstract

A material (200) is disclosed including a matrix (202) and a plurality of particles (204) dispersed in the matrix (202). The plurality of particles (204) include a plurality of tungsten semicarbide particles (206) constituting at least about 30 vol% of the plurality of particles (204). An article (100) is disclosed including the material (200). A method for forming the article (100) is disclosed, including applying the material (200). Applying the material (200) includes forming the matrix (202) and dispersing a plurality of particles (204) including a plurality of tungsten carbide particles (208) in the matrix (202). The plurality of tungsten carbide particles (208) are at least partially decarburized, transforming at least a portion of the tungsten carbide particles (208) into a plurality of the tungsten semicarbide particles (206) such that the plurality of tungsten semicarbide particles (206) constitute at least about 30 vol% of the plurality of particles (204).
