Selection of Thermal Spray Coating Materials

When selecting a coating material, you should first consider the service conditions of the workpiece and the performance characteristics required of the coating. You should also take into account the workpiece’s material, batch size, cost-effectiveness, and the thermal spraying method to be used.

Vacuum plasma spraying of titanium (Ti) and hydroxyapatite (HA) coatings; spraying titanium.

Compared with atmospheric plasma arc spraying, vacuum plasma arc spraying features a faster jet velocity, lower temperature, and controllable atmosphere within the spraying chamber. The coatings produced by this method are more dense, have lower oxygen content, and closely match the composition of the powder used.

Thermal Spray Application Industries and Components

The surface of the paper machine dryer cylinder has scratches, corrosion, and wear. Localized corrosion pits and depressions have formed on the surfaces at both ends of the cylinder body, requiring repair and reinforcement to prevent further corrosion and eventual scrapping. An arc-sprayed stainless steel anti-corrosion and anti-abrasion coating will be applied.

Tungsten carbide spraying on the rotor of an internal mixer

Guangzhou Sanxin utilizes the advanced, U.S.-imported PRAXAIR JP8000 supersonic spraying equipment to apply wear- and corrosion-resistant coatings to tungsten carbide spray-mixed rotor blades, mixing chambers, and sealing devices of internal mixers.

Tungsten carbide wear-resistant coating applied by dispersion disk spraying

Currently widely used in the lithium battery slurry industry, it is suitable for various equipment in the lithium battery sector, including dispersion disks, screw shafts and spiral mixers, wear-resistant components for pulverizers, tanks, cylindrical bodies, conical hoppers, powder feeders, material conveyors, electrode manufacturing equipment, and wear-resistant coatings.
