Description and 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.
