    Product Detail

    Characteristics
    Film properties
    Strong adhesion

    The chromium film has a strong bond with glass, metal, and polymer substrates, making it an ideal adhesion layer material.

    Hardness and wear resistance

    The film hardness can reach 800-1000 HV, which significantly improves the scratch resistance of the device surface.

    Corrosion resistance

    Stable in humid, salt spray and acidic environments, widely used in protective coatings.

    Efficient sputtering performance
    High sputtering rate

    High density (≥7.2 g/cm³) and low oxygen content (≤500 ppm) improve the deposition efficiency.

    Uniform and dense film formation

    The grain size is small (≤30μm), and the film thickness is unevenly distributed ≤5%, which is suitable for coating large substrates.

    Low particle defects

    Ultra-high purity (≥99.95%) reduces particulate contamination during sputtering.

    Compatibility of Chemistry and Technology
    Oxidation resistance

    Forms a dense Cr₂O₃ passivation layer in the air to protect the underlying material.

    Low-temperature deposition capacity

    Can form a film at a low temperature of ≤150°C, compatible with heat-sensitive substrates such as plastics.

    Excellent etching characteristics

    High selectivity with photoresist etching, simple graphic process.

    Frequently Asked Questions (FAQ)
    What are the primary film properties of chromium coatings?
    Chromium films feature strong adhesion to substrates like glass, metal, and polymers. They also provide high hardness (800-1000 HV) for scratch resistance and excellent corrosion resistance in humid, acidic, and salt spray environments.
    Why is chromium considered an ideal adhesion layer material?
    Chromium forms a very strong chemical bond with various substrate materials, including glass, metals, and polymers, making it widely used as an interface layer to improve overall coating adhesion.
    What factors contribute to the high sputtering efficiency of chromium targets?
    The efficiency is driven by high target density (≥7.2 g/cm³), low oxygen content (≤500 ppm), and ultra-high purity (≥99.95%), which together ensure a high sputtering rate and minimal particle contamination.
    Can chromium films be deposited on temperature-sensitive materials?
    Yes. Chromium supports low-temperature deposition capacity (≤150°C), making it fully compatible with heat-sensitive substrates like plastics and polymers.
    How does chromium protect underlying materials from oxidation?
    When exposed to air, chromium naturally forms a dense, stable chromium oxide (Cr₂O₃) passivation layer, which acts as a barrier preventing further oxidation of the underlying substrate.
