Chromium Carbide (CrC) is a compound formed by chromium (Cr) and carbon (C), combining the electrical conductivity of metals with the high hardness of ceramics. Made from high-purity chromium carbide powder via processes such as hot-pressing sintering or spraying, chromium carbide targets exhibit high melting point, high strength, and excellent thermal stability.
In coating processes such as magnetron sputtering and physical vapor deposition (PVD), chromium carbide targets facilitate high deposition rates, resulting in dense, uniform thin films with superior adhesion. These coatings are characterized by exceptional hardness, outstanding wear resistance, and high corrosion resistance, effectively extending the service life and performance stability of the substrate.
With its superior comprehensive properties, chromium carbide targets are widely used in high-end manufacturing, aerospace, electronics, and other fields.
Excellent Characteristics of Chromium Carbide (CrC)
l High Hardness & Wear Resistance, Outstanding Thin Film Protection Performance
As a premier super-hard material, CrC coating offers wear resistance 5 to 10 times greater than conventional metallic films like Chromium (Cr) or Nickel (Ni). When applied to cutting tools, molds, and mechanical components, it significantly enhances wear resistance and anti-seizure properties, extending the operational lifespan of parts by 300% to 500%. It is engineered specifically for extreme wear environments, including high-speed machining and dry friction applications.
l High Temperature & Oxidation Resistance, Adapting to Harsh Environments
It boasts excellent oxidation resistance and can withstand harsh environments such as high-temperature gas, molten metal, and thermal radiation, addressing the problem of high-temperature oxidation and corrosion failure of traditional materials.
l Exceptional Chemical Stability, Superior Corrosion Resistance
It has good tolerance, does not react with most metals and non-metals, and is not prone to oxidation, rust, or degradation.
l Stable Sputtering Performance, High-Quality Thin Films
High Deposition Rate: Under conventional radio frequency sputtering parameters, the deposition rate reaches 50-150 nm/h (up to 120-200 nm/h for high-end Spark Plasma Sintering (SPS) targets), higher than that of similar ceramic targets, making it suitable for mass industrial production.
Wide Applications of Chromium Carbide (CrC)
l Cemented Carbide Tool Coatings
The CrC coating extends tool life by 3 to 5 times, reduces cutting forces by over 30%, and operates effectively at cutting temperatures up to 800–1000°C. These properties make it ideal for efficient processing in demanding automated production lines, such as the mass cutting of automotive components and the precision machining of aerospace structural parts.
l Coatings for Aerospace Engine Components
Specific Applications: High-temperature components such as turbine blades, combustion chambers, guide vanes, turbine discs, and fuel nozzles.
The CrC resists high-temperature gas scouring, hot corrosion, and wear, improves engine thermal efficiency and reliability, extends component service life by 2-3 times, and reduces aerospace operation and maintenance costs.
l Semiconductor Packaging & Protective Coatings
Protects chips from moisture, dust, chemical corrosion, and mechanical scratches, ensures stable electrical performance of devices, and improves the yield of semiconductor products.
l Coatings for Oil & Gas Transmission and Chemical Equipment
The CrC coating effectively addresses the critical challenges of corrosion and wear in pipelines and industrial equipment. By extending service life by 5 to 10 years and significantly reducing leakage risks, and is engineered for the most demanding environments, including deep-sea oil and gas extraction and the transmission of highly corrosive chemical media.
