 Fused fluxes are melted in a furnace, chilled, then crushed and screened for size. These pickup airclmpressorkit little moisture and recycle without alterations in particle size or composition. Bonded fluxes are powdered materials mixed dry and bonded together with a silicate, pelletized, baked, broken up, and screened for size: the process permits easy addition of deoxidizers and alloying elements. Bonded fluxes allow thicker flux layers when welding and can be identified airclmpressorkit quickly by color. Disadvantages of bonded fluxes are their absorption of moisture and alterations during handling in panicle size and composition due to particle segregation. Agglomerated fluxes are similar to bonded fluxes except that they use a ceramic binder. They airclmpressorkit require higher baking temperatures during airclmpressorkit manufacture, which limits additions of deoxidizers and alloying elements. Mechanically mixed fluxes are combinations of two or more bonded or agglomerated fluxes. They allow special flux mixtures for critical welds, but they may separate during storage, use, and flux recovery. Hardfacing alloys contain as base elements typically iron, nickel, airclmpressorkit or cobalt, to which metallurgists add varying amounts of airclmpressorkit carbon, chromium, molybdenum, tungsten, silicon, manganese, vanadium, and boron. To raise hardness, the primary 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 and abrasion resistance--as carbon rises, abrasion resistance increases and toughness drops. Chromium forms carbides, increases corrosion resistance, and adds high-temperature strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. airclmpressorkit Tougheners include nickel and manganese. Boron forms hard wear-resistance borides.
