 Hardfacing alloys contain as base elements typically iron, nickel, or cobalt, to which metallurgists add varying amounts of carbon, chromium, molybdenum, tungsten, aircompressoraccesdories silicon, manganese, vanadium, aircompressoraccesdories and boron. To raise hardness, the primary aircompressoraccesdories property for wear resistance, alloy designers add elements that either form hard constituents (carbides, borides, or Laves phase), or that strengthen the matrix by going into solid solution. Carbon content determines toughness aircompressoraccesdories and aircompressoraccesdories and abrasion resistance--as carbon rises, abrasion resistance increases and toughness drops. Chromium forms carbides, increases corrosion resistance, and adds high-temperature aircompressoraccesdories strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. Tougheners include aircompressoraccesdories nickel and manganese. Boron forms hard wear-resistance borides. Select hardfacing materials based on weld-deposit microstructure and the wear situation the part will encounter, with consideration given to thermal treatments applied to the material before and after hardfacing. Deposit chemistry can be crucial in attaining the desired corrosion resistance or wear properties, or for minimizing the risk of solidification cracking. Acceptable deposit chemistry is achieved through the initial choice of consumables, using wire analysis and flux composition, and by specifying the number of weld passes needed to reduce parent-metal dilution to within acceptable limits. With the submerged-arc aircompressoraccesdories process, the flux and electrode govern the characteristics of the applied hard facing. For example, those fluxes neutral to manganese and silicon are not necessarily neutral to carbon and chromium, elements that matter most in hardfacing.
