The accessories for plasma spraying equipment in the thermal spraying industry are key matching components adapted to mainstream thermal spraying process equipment such as plasma spraying and plasma arc surfacing. They cover a full range of core components including plasma spray gun core assemblies (high-conductivity electrolytic copper electrodes, high-temperature resistant yttria-stabilized zirconia nozzles, insulating ceramic sleeves), precision powder feeding system accessories (anti-clogging powder feeding nozzles, variable-speed powder feeder stators, corrosion-resistant powder pipe joints), arc stability control components (high-frequency arc strikers, current and voltage feedback sensors, plasma gas pressure regulators), cooling and protection accessories (dual-circulation water cooling jackets, heat-insulating protective covers, arc radiation shields), as well as automation-adaptive parts (CNC stroke adjustment modules, spray gun attitude adjustment brackets, signal linkage controllers). All accessories are precision-manufactured from special materials with high conductivity, high-temperature resistance and arc erosion resistance (such as chrome-zirconium copper alloy, high-purity alumina ceramic, high-temperature resistant alloy steel). Among them, the plasma spray gun electrodes adopt the forging forming plus precision grinding process, featuring excellent electrical conductivity and extending the service life by more than 50% compared with ordinary copper electrodes; the yttria-stabilized zirconia nozzles have an inner hole precision controlled within ±0.02 mm, which can ensure the stable constriction of plasma arc column and realize the efficient melting and injection of powder; the dual-circulation water cooling jackets adopt a layered flow channel design, increasing the cooling efficiency by 40% and stably controlling the working temperature of the spray gun within 180℃ to avoid accessory deformation and performance degradation caused by high temperature. These accessories boast core advantages such as strong adaptability, high arc stability, outstanding wear resistance and low maintenance cost, which can significantly improve the coating deposition efficiency, coating density and composition uniformity of plasma spraying equipment, and reduce equipment failure rate and downtime. Backed by a sound R&D and production system, we can provide customized accessory solutions for plasma spraying equipment of different brands and models (such as F4 and SG-100 series), covering the entire process services including accessory size customization, material selection optimization and performance parameter matching. Widely used in thermal spraying fields such as aero-space component coating preparation, metallurgical machinery part wear strengthening, medical device surface modification and new energy equipment component anti-corrosion treatment, these accessories meet the stringent requirements for the efficient and stable operation of various plasma spraying equipment and the preparation of high-quality coatings.
