Product Name: Hafnium Carbide Powder

Brief Description of Hafnium carbide powder HfC: 

Hafnium carbide ( HfC) is a chemical compound of hafnium and carbon

With a melting point of about 3900 °C it is one of the most refractory binary compounds known.

However, it has low oxidation resistance, with the oxidation starting at temperatures as low as 430 °C

Hafnium carbide is usually carbon deficient and therefore its composition is often expressed as HfCx (x = 0.5 to 1.0). It has a cubic (rock-salt) crystal structure at any value of x

 Application of Hafnium carbide powder HfC:

1. Used for preparation of ultra-high temperature ceramics
2. The reactant in the synthesis of hafnium-containing organometallic polymers
3. Used as an additive in alloys
4. Used in coatings
5. Widely used in microelectronics, semiconductor, aerospace high-temperature resistant material, coating materials, ceramic materials, ceramic target material, etc.

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.

Product Name: Chromium Carbide Cr3C2 Powder

Chromium Carbide Cr3C2 Powder APPLICATION FIELDS

Chromium Carbide Cr3C2 Powder is a ceramic compound that exists in several different chemical compositions: Cr3C2, Cr7C3, and Cr23C6. At standard conditions, it exists as a gray solid.

It is extremely hard and corrosion-resistant.

It is also a refractory compound, which means that it retains its strength at high temperatures as well.

These properties make use as an additive to metal alloys. When chromium carbide crystals are integrated into the surface of a metal it improves the wear resistance and corrosion resistance of the metal and maintains these properties at elevated temperatures.

Cr3C2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a protective layer. This layer is essentially its own metal matrix composite, consisting of hard ceramic Cr3C2 particles embedded in a nickel-chromium matrix.

Cr3C2 prevents large grains from forming in the composite, which results in a fine-grained structure of superior toughness.

Chromium Carbide Cr3C2 Application:

1. Used as high temperature resistant and wear-resistant surface materials
2. Used for welding and flux-cored wire
3. Chromium carbide is useful in the surface treatment of metal components.
4. Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying.
5. Chromium carbide is used as an additive in cutting tools in order to improve toughness by preventing the growth of large grains.

Chromium Carbide Cr3C2 Properties:

There are three different crystal structures for chromium carbide corresponding to the three different chemical compositions. Cr₂₃C₆ has a cubic crystal structure and a Vickers hardness of 976 kg/mm². Cr₇C₃ has a hexagonal crystal structure and a microhardness of 1336 kg/mm².

Cr₃C₂ is the most durable of the three compositions and has an orthorhombic crystal structure with a microhardness of 2280 kg/mm². For this reason, Cr₃C₂ is the primary form of chromium carbide used in surface treatment.
