Thermal spray is a collective name for a set of processes in which coating material is heated quickly in a hot gaseous medium, and simultaneously projected at a high velocity onto a prepared substrate surface, where it deposits to produce the desired thickness of the coating. The coating materials (metallic, ceramic, cermet, and some polymeric) in the form of powder, wire, or rod fed to a heating zone to become molten and are propelled from there to the surface of the substrate material.
The production rate and adhesion strength of the thermal spray coating process are very high as compared to other coating processes. Due to its several advantages such as low cost, versatility, and high processing speed it is most widely used in aircraft engines, thermal power plants, bridges, the photochemical industry, automotive systems, chemical process equipment, dies, marine turbines, and power generation equipment.
It is mainly used to apply the coating to a numerous range of materials and machine parts to impart resistance to erosion, corrosion, wear, and cavitation. Except this, it provides lubricity, sacrificial wear, electrical conductivity, low or high friction, and chemical resistance.
Thermal Spray Equipment Manufacturer
We are the Manufacturer & Supplier of thermal spray equipment, thermal Spray Gun, Spray Gun parts, Products & equipment in Jodhpur, Rajasthan, India. Thermal spray is a term for a group of processes in which ceramic, metallic, cermet and some polymeric materials in the form of wire, powder, or rod are fed to a torch or gun with which they are heated to near or over their melting period. The resulting molten or generally molten droplets of material are expedited in a gas stream and projected against the surface to be coated .the droplets flow into thin lamellar particles adhering to the surface, overlapping and interlocking as they set. The complete coating thickness is usually generated in multiple passes of the coating device. we have Thermal Spray Equipment Manufacturers in India.
