Do you know the boronization process of iron boride?

What is iron boride

Iron boride, the molecular formula is BFe, and the molecular weight is 66.656. It is a gray orthorhombic diamond crystal. It can also be a gray powder that is insoluble in water. Mainly used as a chemical reagent, can also be used as a hydrogenation catalyst. There are two main forms of iron boride. Some iron boride has magnetism, conductivity, corrosion resistance and extremely high hardness; some iron boride is used as a hard coating for iron. Iron boride itself has the high hardness of ceramics, as well as the thermal and electrical conductivity of metals. Iron boride coating has excellent mechanical properties, friction and corrosion resistance.

Ferro Boron

The iron alloy mainly composed of boron and iron also contains impurities such as aluminum, silicon, carbon, manganese, and copper. Iron boride is a boron additive for steel smelting, cast iron, amorphous alloys and magnetic materials. The physical and chemical properties of iron boride are non-toxic, odorless, non-irritating, good thermal stability and heat resistance, strong ultraviolet shielding effect, good dispersion and weather resistance, and have obvious sterilization, antibacterial and antibacterial properties against harmful bacteria. Antibacterial effect. , Can accelerate the degradation rate of plastic products.

Puffing process

The boron-rich compound can form an iron boride mixture on the iron surface through a thermochemical reaction. This process is called boronization. There are many methods for forming boride coatings, including gas boronizing, molten salt boronizing and filling boronizing. The typical boride layer is carbon tetraboride (b4c) or crystalline boron, which is sintered in a tetrafluoroboric acid flux to form a coating on the iron surface. Boron atoms can diffuse into the iron matrix in the range of 1023 to 1373 K. The range of compounds and composition they form depends on the reaction conditions, including temperature and surrounding environment. Iron and boron simply react in a high-temperature inert gas furnace or microwave to form massive iron boride.

Boronizing, this process can usually be used to improve wear resistance, corrosion resistance, wear resistance and oxidation resistance. It can also be widely used in oil and gas refining, chemical extraction, automotive, agriculture, stamping, textile extrusion, injection molding and other industries. Iron-based coatings have recently received extensive attention from the industry due to their special mechanical, friction and corrosion resistance properties. Compared with ceramics or cermets that people have used before, iron-based materials are relatively cheap, and can be produced economically by various thermal methods, and are easy to manufacture and process.

Overview of iron boride FeB powder

Iron boride (FeB) is a gray powder and is insoluble in water. FeB is harder than Fe2B, but it is more fragile and more likely to break on impact. Feb is a soft ferromagnetic compound that becomes paramagnetic at temperatures above 325°C (617°F). FeB powder begins to react with ambient oxygen in the air above 300°C. Although a large amount of FeB material is expected to remain stable in air, FeB is a very hard compound (measured by Vickers indentation at 15-22 GPa), which is not ideal for bonding steel. Because the FeB layer is fragile and easily peels off steel or iron.

In February there is a zigzag chain of boron atoms coordinated by seven iron atoms. The boron atom has a slightly twisted single-ended triangular triangular prism iron atom ligand and two boron atom neighborhoods. BB single bond pitch is 178 PM, Fe-B single bond pitch is 215-220 PM, Fe-Fe single bond pitch is 240-272 PM. Each triangular prism shares two rectangular faces with nearby prisms, thus forming an infinite prism sequence.

FeB single crystals are occupied by bond domains. The binding domain is parallel to the easy axis and perpendicular to the hard axis. The structure of the closed domain is described as "stars and twists". The key field has a clear direction on the boundary of the home field, while the closed field is diamond-shaped.

Application of iron boride FeB powder

Iron-based coatings have recently received attention due to their mechanical, friction, and corrosion resistance. Compared with ceramics or cermets used by humans before, iron-based materials are relatively cheap and less strategic, can be produced economically by a variety of thermal methods, and are easy to manufacture and process.

Iron boride is generally used to improve wear resistance, corrosion resistance, wear resistance and oxidation resistance.

Iron boride is used in oil and gas refining, chemical extraction, automotive, agriculture, stamping, textile extrusion and injection molding industries.
