Hardfacing composition and article having hardfacing deposit

摘要

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.

1. A hardfacing composition comprising a plurality of hard particles wherein the hard particles comprise a mode particle size distribution present in an amount equal to a mode particle size weight percent of the hard particles in the hardfacing composition, one particle size distribution smaller than the mode particle size distribution and present in an amount equal to a one particle size weight percent of the hard particles in the hardfacing composition, and an other particle size distribution larger than the mode particle size distribution and present in an amount equal to an other particle size weight percent of the hard particles in the hardfacing composition; there being a substantially smooth transition between the mode particle size distribution and the one particle size distribution and there being a substantially smooth transition between the mode particle size distribution and the other particle size distribution; and wherein the one particle size weight percent ranges between about 40 percent and about 50 percent of the mode particle size weight percent, and the other particle size weight percent ranges between about 60 percent and about 72 percent of the mode particle size weight percent.
