Product Name: Ferro Titanium Carbide Powder

Ferro Titanium Carbide Powder Applications Fields:

Ferro Titanium Carbide Powder is a ferroalloy, an alloy of iron and titanium with between 10–20% iron and 45–75% titanium and sometimes a small amount of carbon. Ferrotitanium can be manufactured by mixing titanium sponge and scrap with iron and melting them together in an induction furnace.

During steelmaking, titanium is usually introduced as ferrotitanium because of its relatively low melting temperature and high density.

Ferrotitanium is usually produced by induction melting of titanium scrap with iron or steel; however, it also is produced directly from titanium mineral concentrates.

Application of Ferro Titanium carbide powder:

In the present study, Fe-based hardfacing coating reinforced by TiC particles was obtained by manual shielded metal arc welding (SMAW) in which H08A bare electrode was coated with fluxes, to which different measures of ferrotitanium, rutile, graphite, calcium carbonate, and calcium fluoride had been added.

The microstructure and wear properties of the hardfacing coating were studied through scanning electron microscopy (SEM), transmission electron microscopy (TEM), an X-ray diffractometer (XRD), and a wear test.

The results indicate that TiC particles are produced by a direct metallurgical reaction between ferrotitanium and graphite during welding.

TiC particles are uniformly dispersed in the matrix of lath martensite and retained austenite with particle sizes in the range of 3–5 μm. Fe-based hardfacing coating reinforced by TiC particles is found to possess better wear resistance and a lower coefficient of friction than that of the AISI 1045 steel substrate.

Niobium Boride Powder

Product Name: Niobium Boride Powder

Niobium Boride Powder Related Information

Niobium boride powders having NbB, NbB2 and Nb3B4 phases in various amounts and single phase NbB powders were successfully synthesized by using powder metallurgy methods from related metal oxide raw materials in the presence of a strong reducing agent. Nb2O5, B2O3 and Mg powder blends were milled at room temperature

A high-energy ball mill for different time. Subsequently, an undesired MgO phase was removed from the milled powders by HCl leaching to constitute NbB–NbB2–Nb3B4 as final products, and they were subjected to an annealing process at 1500 °C for 4 h to observe probable boride transformation. Characterization was carried out by XRD, DSC, PSA, SEM/EDX, TEM, and VSM. The effects of milling time (up to 9 h) on the formation, microstructure, and thermal behavior of the final products were investigated.

The reduction reaction took place after milling stoichiometric powder blends for 2 h. Nano-sized NbB–NbB2–Nb3B4 powders in high purity were obtained in the absence of any secondary phase and any impurity via mechanochemistry by milling for 5 h and leaching with 4 mol/L HCl. After annealing, pure and nano-sized NbB–NbB2–Nb3B4 powders transformed into a single NbB phase without leaving behind NbB2 and Nb3B4 phases.

Tungsten Carbide Powder

Product Name: Tungsten Carbide Powder

Brief Description of WC Tungsten Carbide Powder

Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms.

In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

Physical Properties of WC Tungsten Carbide Powder

Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1.

Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600.

It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa.

It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31.

Chemical Properties of WC Tungsten Carbide Powder

There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C.

Both compounds may be present in coatings and the proportions can depend on the coating method.

At high temperatures, WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high-velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.

Application of WC Tungsten Carbide Powder 

1 Used for Producing high capability nano-crystalline or superfine horniness alloy, hard-face abrasion-resistant spraying and petrochemical cracking catalyst;

2. Used for chipless forming tools; Cutting tools; Mining tolls; Nano-composites (for enhanced hardness, strength, and wear resistance);
3. Used for erosion-resistant coatings; wear-resistance coatings; Corrosion-resistant coatings; Wear-resistant parts
4. To produce hard carbide.
