Tungsten carbide spray coating for mixing equipment dispersing discs

Tungsten Carbide Coating for Mixing Equipment Agitator Disks—Our company uses the Plascoat JP8000 equipment from U.S. Plascoat to apply tungsten carbide coatings. The performance parameters of our tungsten carbide coating, applied using the U.S. Plascoat JP8000 equipment, are as follows: Hardness: Above HV1300 (HVAF); Porosity: Less than 0.5% (HVAF); Bond Strength: Greater than 80 MPa (HVAF). If your products have extremely high requirements for surface finish and dimensional accuracy, or if they will be in long-term contact with liquids and demand enhanced wear resistance and corrosion protection, you should choose our tungsten carbide coating applied using the U.S. Plascoat JP8000 equipment. We have accumulated extensive experience in material, equipment, process, and solution development for coating applications, and we are currently replicating these successful cases. We will guide you through the entire coating manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution covering materials, equipment, and processes all in one package; coating trials conducted either at your site or at our technical center; and consistently high coating quality and efficiency.

Lithium battery equipment spray-on wear-resistant and insulating coating made of tungsten carbide.

1. Roller pressing is the most commonly used compaction process for lithium-battery electrode sheets. Compared to other processing methods, roller pressing significantly alters the pore structure of the electrode sheets and also affects the distribution of conductive additives, thereby impacting the electrochemical performance of the battery. 2. Based on comparative analyses with multiple electrode-sheet rolling machines and in alignment with the needs of battery manufacturers, our company has developed a high-precision, high-strength coating for battery electrode-roll rollers. This coating specifically enables precise control over the shape of the electrode sheets, effectively addressing the issue of uneven thickness—where the center of the sheet becomes thicker while the edges remain thinner—caused by deflection and deformation of the rollers during the rolling process. We have accumulated extensive experience in coating application across materials, equipment, processes, and solutions, and we are now replicating these successful cases. We will guide you through the entire coating-manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution covering all aspects—from materials and equipment to processes; coating trials conducted either at your site or at our technical center; and consistently high coating quality and efficiency.

Tungsten Carbide Coating for JP8000 Device

Our company uses the American Plax JP8000 equipment to apply tungsten carbide coatings to highly wear-resistant, ultra-smooth rollers. The performance parameters of our tungsten carbide coatings are as follows: Hardness: HV1300 or higher (HVAF); Porosity: Less than 0.5% (HVAF); Bonding Strength: Over 80 MPa (HVAF). If your products demand exceptionally high surface finish and dimensional accuracy, or if they will be in long-term contact with liquids and thus require enhanced wear resistance and corrosion protection, you should choose our tungsten carbide coatings applied using the American Plax JP8000 equipment. We have accumulated extensive experience in coating application—covering materials, equipment, processes, and solutions—and we are currently replicating these successful cases. We will guide you through the entire coating manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution that encompasses everything—from materials and equipment to processes; coating trials conducted either at your site or at our technical center; and consistently high coating quality and efficiency.

Using the supersonic flame spraying process, a tungsten carbide coating is applied to enhance the mold surface’s hardness, wear resistance, and corrosion resistance.

It is indeed feasible and effective to replace rubber and resin linings with a ceramic coating applied to metal roller bodies via thermal spray coating technology. Industrialized countries such as the United States and Japan have developed ceramic coatings for corona rollers and have achieved successful applications on these rollers.

Spray-on repair for worn areas of fan impeller blades

Our company provides repair services for worn areas on fan impellers in cement plants, power plants, and other facilities, as well as surface enhancement coatings for new impellers, which can extend the service life of impellers by several times. We employ a supersonic thermal spraying technique using tungsten carbide coatings, resulting in dense coatings with high hardness and excellent wear resistance, thereby significantly prolonging the service life of components. Tungsten carbide powder coatings—Tungsten carbide (WC) is the primary raw material used in the production of cemented carbides and boasts exceptionally high microhardness. Commonly used WC-based powder coatings include WC 8% Co, WC 12% Co, and WC 17% Co. The addition of cobalt in varying proportions to WC primarily serves as a binder, enhancing the toughness of the coating while preventing excessive carbon burn-off during the spraying process. Chromium carbide (Cr2C3) features high hardness and exhibits excellent resistance to high-temperature oxidation and wear, with a maximum operating temperature of up to 800°C. Typically, Cr2C3 is mixed with Ni-Cr alloys and is mainly applied to high-temperature wear-prone areas. Mechanical component wear-repair coating process using tungsten carbide—tungsten carbide wear-resistant coating parameters: Processing steps: → Sandblasting → Preheating → Primer application → Tungsten carbide spraying (thickness: 0.04–1.0 mm) → Grinding; Processing methods: Plasma or supersonic flame spraying. Tungsten carbide coating performance indicators: Hardness: Up to HRC 70–80; Bonding strength: ≥90 MPa; High-temperature resistance: Above 1200°C; Coating thickness: 0.04 mm–1.0 mm; Service life: 3–6 times longer than that achieved by conventional methods. Processing range: Diameter—from tens of millimeters to hundreds of millimeters; Length—from several millimeters to several meters.
