ChroMiuM boride Chemical Properties,Uses,Production
Chemical Properties
-150, +325 mesh with 99.5% purity; refractory material; high melting point, very hard, very high corrosion resistance; used as metallurgical additive and as a sputtering target to produce films, which can be wear-resistant and semiconducting [KIR78] [HAW93] [CER91]
Uses
Chromium boride,is been used in plasma technology and for high-performance electrodes in electron microscopes, metal matrix composites (MMCs), cutting tools and cermets for machining aluminum. chromium diboride is recognised as offering superior performance in corrosive-wear environments. Chromium diboride thin films possess desirable combinations of properties, which are attractive for a wide range of potential industrial applications. As a wear-resistant component of weld materials and powders for spraying in engineering and metallurgy, Protection of outer surfaces and bearing surfaces of machine parts against abrasive wear by plasma spraying, In aluminum evaporators manufacturing and for aluminum electrolyzes repair work, In nuclear engineering as neutron absorption material.
Flammability and Explosibility
Not classified
Industrial uses
Chromium boride occurs as very hard crystallinepowder in several phases: the CrBorthorhombic crystal, the hexagonal crystalCr2B, and the tetragonal crystal Cr3B2. Chromiumboride parts produced by powder metallurgyhave a specific gravity of 6.20 to 7.31,with a Rockwell A hardness of 77 to 88. Theyhave good resistance to oxidation at high temperatures,are stable to strong acids, and havehigh heat-shock resistance up to 1316°C. Thetransverse rupture strength is from 552 to 931MPa. CrB is used for oil-well drilling. A sinteredmaterial, used for gas-turbine blades, contains85% CrB with 15% nickel binder. It hasa Rockwell A hardness of 87 and a transverserupture strength of 848 MPa.
