Surface Engineering’s Ferro-Carboride Alloy Series is a revolutionary blend of boride and carbide forming elements suspended in a unique iron based matrix that forms a refined glass-like micron/sub-micron microstructure during welding. The high volume fraction of complex boro-carbide phases that form during solidification provides extreme abrasion resistance. As these phases are near nano-scale in size, concentration sites are reduced minimizing the initiation of cracking and crack propagation. The weld metal chemistries and resulting microstructure provide high to extremely high hardness, even at elevated temperatures. Combined with significant toughness, impact and galling resistance, the corrosion resistance of the series is incredible, and in some applications, supersedes nickel base super alloys.
