In response to the demands of various plastic products, most of the ultra-engineering plastics currently in use contain additives such as flame retardants, glass fibers, calcium carbonate, and modifiers, which lead to rapid corrosion, wear, and shortened service life of the barrel and screw. This process ensures that the sprayed alloy layer is completely resistant to peeling, cracking, and porosity, and strictly controls issues such as workpiece deformation.

In the new-energy lithium-battery industry, various types of equipment—such as screw shafts, screw conveyors, battery raw-material crushers, mixers, conical hoppers, powder feeders, and feeding machines—are coated with wear-resistant tungsten carbide coatings on their surfaces.

Wear-repair and pre-protection reinforcement for automotive engine mounts, synchronizer rings, crankshaft components; wear-resistant coating repair for gearbox bearing housings, hydraulic cylinder pistons, front and rear axle support shafts, mast guide rails, main bearing journals of engine crankshafts, rocker arm shafts, half-shaft oil seal positions, pin shafts, cylinder bed sealing surfaces, wheel hubs, and universal joint wear areas; as well as spray-on manufacturing of piston rings and valve tappets. Wear-resistant coating application for dredger rake heads, wear-resistant rings, mud buckets, cutter blades, shovel teeth, mud pump impellers, ship propeller shafts, propeller shaft sleeves, eccentric shaft sleeves, gear transmission shafts, mud pump water seal necks, mud gate slides, sand-gravel machine scrapers, ship propellers, and thrusters; thermal spraying of corrosion-resistant alloy materials and plastics for decks, hulls, guardrails, iron anchors, and other components.

The zirconia coating on the surface of the graphite boat dish was processed using a plasma spraying device, and its surface roughness has been improved.

The threaded steel used in high-speed railway bridges and tunnels is coated with a rare-earth corrosion-resistant alloy material using Guangzhou Sanxin’s high-power arc equipment equipped with imported spray guns.
