Plasma Spraying Equipment

Plasma Spraying Equipment is a high-performance surface strengthening and repair equipment that utilizes high-temperature plasma jet generated by plasma arc to heat spray powder to a molten or semi-molten state, which is then deposited on the workpiece surface at high speed to form a high-performance coating. Its core advantages lie in the extremely high temperature of the plasma jet (up to 10000K or above), which can easily melt refractory metals such as tungsten and molybdenum as well as special materials like ceramics. The coating bonds closely with the substrate, enabling precise preparation of coatings with low, medium, and high porosity. Meanwhile, it features a wide range of applicable spray materials and strong construction flexibility, capable of meeting diverse requirements for surface performance improvement.

Relying on advanced technological R&D capabilities and rich industry experience, we can provide customized plasma spraying equipment solutions for global customers. According to the spraying needs of customers in different industries, we can tailor-make solutions covering the selection of plasma spray gun models, matching of plasma arc power supply parameters, precise regulation of powder feeding systems, design of equipment automation integration, planning of spraying process paths, and adaptation of supporting consumables. Whether it is the local coating preparation of small precision components, surface strengthening of medium-sized parts, or repair and reinforcement of key parts of large-scale equipment, we can accurately match the customer's production conditions and technical indicators, helping customers optimize production processes and improve workpiece service performance.

This equipment is widely used in aerospace, power energy, automotive manufacturing, mechanical equipment, medical devices, rail transit and other fields. It can meet the diverse surface strengthening and dimension recovery needs of various core components, such as wear resistance, high temperature resistance, corrosion resistance, insulation, and thermal conductivity. Examples include the preparation of thermal barrier coatings for aeroengine blades, anti-corrosion and wear-resistant treatment of power plant boiler pipes, strengthening of automotive engine piston rings, and surface modification of medical device implants.

The spray powders suitable for this equipment are extremely rich, covering three categories: metal powders, ceramic powders, and cermet composite powders. Specific models include: Al₂O₃, ZrO₂, Cr₂O₃, NiCrAlY, CoCrAlY, WC-CoCr, Mo, Ti, etc. Among them, Al₂O₃ and Cr₂O₃ ceramic powders have excellent insulation and corrosion resistance, suitable for electrical components, mechanical seals and other parts; ZrO₂ powder has outstanding high-temperature resistance and thermal insulation performance, and is the core suitable material for thermal barrier coatings of aeroengines; NiCrAlY and CoCrAlY metal powders have strong oxidation resistance and can be used as transition coatings or working coatings for high-temperature components; WC-CoCr composite powder has both high hardness and wear resistance, suitable for the strengthening and repair of vulnerable parts of heavy-duty machinery.
