Abstract: A hardfacing composition (32) that includes a plurality of hard particles (54) wherein the hard particles (54) include a mode particle size distribution, one particle size distribution smaller than the mode particle size distribution, and an other particle size distribution larger than the mode particle size distribution. There is an absence of any substantial fluctuations in the particle size distribution between the mode particle size distribution and the one particle size distribution. There is an absence of any substantial fluctuations in the particle size distribution between the mode particle size distribution and the other particle size distribution.
