In chemistry a boride is a chemical compound between boron and a less electronegative element, for example silicon boride (SiB3 and SiB6). The borides are a very large group of compounds that are generally high melting and are not ionic in nature. Some borides exhibit very useful physical properties. The term boride is also loosely applied to compounds such as B12As2 (N.B. Arsenic has an electronegativity higher than boron) that is often referred to as icosahedral boride.
Iron boride refers to various inorganic compounds with the formula FexBy. Two main iron borides are FeB and Fe2B. Some iron borides possess useful properties such as magnetism, electrical conductivity, corrosion resistance and extreme hardness. Some iron borides have found use as hardening coatings for iron.
Properties
Iron borides have properties of ceramics such as high hardness, and properties of metal properties, such as thermal conductivity and electrical conductivity. Boride coatings on iron are superior mechanical, frictional, and anti-corrosive.
Iron monoboride (FeB) is a gray powder that is insoluble in water. FeB is harder than Fe2B but is more brittle and more easily fractured upon impact. Iron monoboride is only made in single layer.
Iron boride (Fe2B) is a submicron and nanopowder that is also insoluble in water. They have been found to be superconductive and ultra-incompressible. It can be made in both single or double layer.
Applications
Boriding is often used to improve abrasion resistance, corrosion resistance, wear resistance, and oxidation resistance. It is used in oil and gas refinery, chemical extraction, automotive, agricultural, stamping, textile extrusion and injection molding industries.
Iron based coatings recently gained attention for their mechanical, frictional, and corrosion resistant properties. As compared to the ceramic or cermet type of materials people have used before, iron based materials are relatively inexpensive, less strategic, and can be produced economically by various thermal methods with ease of fabrication and machining.
