High-Temperature Oxidation Resistant DG.NiCrCoAlY Ceramic Primer Powder - Reliable China Suppliers & Factory

In the realm of thermal spraying, ceramic materials are essential, particularly in high-temperature and corrosion-resistant applications. These materials are increasingly utilized as thermal barrier coatings due to their outstanding resistance to high temperatures and thermal corrosion. They find extensive use in the coating of aircraft engines and various components that operate under extreme conditions. However, the significant difference in thermal expansion coefficients between ceramic materials and steel substrates often leads to inadequate adhesion when ceramics are directly applied to the substrate. To enhance bonding effectiveness, it is crucial to apply a ceramic material primer before the spraying process. As a leading China supplier and factory of premium ceramic materials, we ensure high-quality products designed to meet rigorous industry standards, delivering superior performance in thermal spraying applications

    Product Performance

    DG.NiCrCoAlY powder is produced by gas atomization, has good spherical shape and uniform fluidity, and is easy to spray. Its working environment temperature can reach up to 950 degrees Celsius, showing excellent high temperature resistance and thermal corrosion resistance. This makes DG.NiCrCoAlY often used as high-temperature primer and high-temperature anti-oxidation coating, which can effectively delay the oxidation failure of the substrate and extend the service life of the equipment.
    In addition, DG.NiCrCoAlY is often used as a base layer for high-temperature corrosion-resistant coatings and thermal barrier coatings to ensure reliability under extreme conditions. Its excellent high-temperature resistance makes it widely used in aerospace and industrial steam turbines.
