In the relentless environment of industrial sifting and particle separation, standard screens are often eroded by abrasive powders and high-speed friction. Our High Chromium Alloy Coating, applied through advanced Supersonic (HVOF) Spraying, provides a metallurgical shield that redefines component durability. By fusing a dense, chromium-rich matrix onto your screen surfaces, we ensure that your equipment maintains its precision and structural integrity under the most punishing conditions.
Process Technology: High-Velocity Oxygen Fuel (HVOF) Supersonic Spraying.
Primary Material: Cr3C2-NiCr (Chromium Carbide-Nickel Chromium) Alloy.
Core Benefit: Dramatically extends the wear life of vibrating and supersonic screens.
Operational Impact: Minimizes mesh blinding and maintains consistent particle sizing.
Customization: Tailored coating thickness and porosity levels based on your specific material abrasive profile.

Picture the interior of a high-capacity vibrating screen. Millions of sharp, abrasive particles strike the metal mesh every hour, acting like microscopic chisels. This is where most screens fail, leading to costly production halts. Our High Chromium Alloy Coating was engineered to solve this exact problem. When you inspect a screen treated with our supersonic process, you see a satin-like, ultra-dense metallic finish that feels incredibly hard to the touch—a surface that laughs at the friction of iron ore, carbide powders, or glass beads.
This coating isn't just a layer; it’s an evolution. During the supersonic application, the chromium alloy particles are propelled at speeds exceeding 800 meters per second. Upon impact, they "splat" and interlock, creating a coating so dense that corrosive agents cannot find a path to the base metal. The sound of a coated screen in operation is different—it’s a steady, solid hum of a system working at peak efficiency, rather than the rattling of a worn-out component. By investing in this surface defense, you aren't just buying time; you are ensuring that your output remains pure and your maintenance schedule stays predictable.
Our supersonic screen coating is a synergy of material science and aerodynamic force, designed for industries where performance is measured in years, not months.
Supreme Abrasion Resistance: The high volume fraction of chromium carbides provides a hardness profile that deflects the most aggressive particles, preventing the "rounding" of screen apertures that causes sifting inaccuracies.
High-Temperature Oxidation Defense: Unlike standard polymers or chrome plating, our NiCr-based alloy maintains its structural strength and chemical stability even at temperatures reaching 850°C, making it ideal for hot sifting applications.
Ultra-Low Porosity Levels: Our HVOF process achieves a coating density of over 99%. This prevents "under-film" corrosion, ensuring the coating never flakes or delaminates even in humid or chemically reactive environments.
Enhanced Flow Characteristics: The fine-grained surface reduces the coefficient of friction, allowing powders to glide over the screen more efficiently, which reduces energy consumption and mesh blinding.
To understand why this coating outperforms traditional hard-facing, one must look at the micro-structural level. In our supersonic process, we utilize a "cermet" powder—a ceramic carbide embedded in a metallic binder.
The NiCr Matrix Advantage
The Nickel-Chromium binder acts as a tough, ductile "glue" that holds the incredibly hard Chromium Carbide crystals in place. While the carbides resist wear, the NiCr matrix absorbs the impact energy of large particles, preventing the surface from becoming brittle.
Supersonic Kinetic Energy
Traditional spray methods rely on heat, which can oxidize the alloy before it hits the target. Our supersonic process uses kinetic energy. The particles are moving so fast that they forge a mechanical bond with the screen substrate upon impact, resulting in a coating that is essentially a part of the screen itself. This eliminates the risk of "peeling" that often plagues lower-quality electroplated or thermally sprayed alternatives.
Our High Chromium Alloy coating is the standard for high-stakes screening operations across the globe.
Advanced Materials Processing: Crucial for the sifting of tungsten carbide, nickel, and cobalt powders where zero contamination and high precision are required.
Mining and Minerals: Protection for screens handling crushed ores, abrasive minerals, and heavy aggregates that usually erode steel in days.
Chemical & Waste Incineration: Ideal for hot ash sifting and chemical separation where the combination of high heat and corrosive gases destroys standard stainless steel.
Energy Sector: Used in the screening of fly ash and solid fuels in power plants to ensure consistent particle feed for burners.
Q: Will the coating clog the screen mesh apertures?
A: No. We carefully control the spray parameters and utilize specialized masking techniques to ensure the chromium alloy is applied only to the wear surfaces, maintaining the original precision of your screen openings.
Q: Can this coating be applied to fine mesh screens?
A: Yes. We have developed high-velocity protocols that allow for the application of thin, dense coatings on wires as small as 0.5mm without causing thermal distortion or structural damage.
Q: How does this compare to Tungsten Carbide (WC) coatings?
A: While Tungsten Carbide is harder, Chromium Alloy is superior in high-temperature or corrosive environments. If your process exceeds 500°C or involves acid exposure, Chromium Alloy is the more durable choice.
Q: Is it more cost-effective to coat a screen or buy a new one?
A: Coating typically costs a fraction of a high-end stainless steel screen. Given that it can extend the life of the screen by 3-5 times, the return on investment is achieved within the first few weeks of operation.
