Boronizing is a new technology of chemical heat treatment, the iron and steel workpiece after boronizing treatment, the surface hardness of HV1300-2300 (equivalent to HRC70 above), can be glass, it not only has excellent wear resistance, also has the very high heat resistance (650) and excellent corrosion resistance especially adapted to all kinds of cold hot mold, all kinds of brick and tile cement slurry pump work under abrasive wear of the mold and accessories, all kinds of petrochemical machinery in sediment hydrogen chloride or other corrosive gas work under the working conditions of stainless steel heat resistant steel stem separator shell and nozzleMore suitable for textile machinery guide plate and other accessories working under high speed friction and friction loss after boriding, the service life of the workpiece can be increased 1-10 times.

Boron carbide used in carbon refractory antioxidant effect, can make the product densification, prevent the oxidation of carbon in carbon refractory, during 1000 ~ 1250 at the same time, the reaction of Al2O3 and B2O3, generate 9 2 B2O3 columnar crystal Al2O3, distributed in the matrix and the clearance of refractory, thereby the porosity is decreased, the increase in temperature strength, and the generated 9 2 B2O3 crystal Al2O3, volume expansion, can heal volume shrinkage, reduce crack.

Boron carbide in more than 1300 C, it is more hard than diamond and boron nitride almost the price advantage is an ideal substitute for diamond and boron nitride boron carbide flexure strength of 50000-70000 psi, the compressive strength of 414000 psi boron carbide thermal conductivity is very low (29-67 W/mK), the range of 0.1-10 ohm resistance coefficient - cm based on the above excellent physical properties, the purpose of the boron carbide is quite extensive.
