Thermal Spray Gun

The thermal spray gun is a coating process in which finely divided metallic or nonmetallic materials. That consists of a heat source and a coating material in a powder. The coating material may be in the form of molten materials, powder, ceramic-rod, or wire, which is melted into small droplets and sprayed onto surfaces at large velocity.

Thermal spray coating is normally utilized to metallic substrates but also can be carried out to a few plastic substrates. This form of coatings uniquely complements and improves the performance of the thing.

Types of Thermal Spray Gun

There are numerous types of processes used to use a thermal spray coating. They may be the following:

·         Metalizing Gun

·         Flame Spray Gun

·         Arc Spray Gun

·         HVOF Gun

·         Zinc Spray Gun

·         Plasma Thermal Spray Gun

Metalizing Gun - In this metalizing gun the metal takes place with the help of heat. In this, heat melts the metal wire into the liquid. Then it is sprayed on the surface of the subject. On part of abrasive media, we can take rod, wire, and powder to feed inside the gun.

Flame Spray Gun – Flame Spray Gun spraying generally requires only low-cost equipment. It is appropriate for single-piece and series production may be used in both stationary and mobile configurations. Its main applications are corrosion and wear protection. The usage of wire or powder relies upon at the material and the application rate. Zinc, aluminum, and molybdenum are mostly sprayed as wire. Most metal and hard alloys are applied as a powder.

Arc Spray Gun – In this gun, two arcs of wire are generating with the help of an electric supply anode and cathode. These wires when touched generate the spark which leads to heat to the two-wire. Melts down and sprayed over the subject.

HVOF Gun - HVOF Gun known as High-Velocity Oxy-Fuel. HVOF Gun is a thermal spray system utilizing the combustion of gases or liquid. Combustion gases such as hydrogen and liquid fuel such as kerosene are used. Fuel and oxygen combine and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure required for coating.

Zinc Spray Gun - In this, different abrasive media can be used for spraying on the subject. Like anti-corrosive abrasive is used for protecting the surface from corrosion. Other times, a Zinc spray gun, the Aluminum spray gun is used.

Plasma Flame Spray Gun - Plasma fire spray gun is utilized for both huge surfaces just as little inward bore widths surface coatings. Plasma spray measure incorporates the spraying of liquid or warm mollified materials onto a surface to give a covering. Plasma spray gun creates adequate energy to liquefy practically any material in powder structure makes them appropriate for an enormous assortment of surface coatings.

Working of Thermal Spray Gun

Thermal Spray coating technology sprinkle can provide you with thick coatings (approx. thickness scope is 22 microns to several mm, depending on the technique and feedstock), over a massive place at a excessive announcement fee compared to more coating strategies including electroplating, physical and chemical vapor declaration. Thermal Spray gadget is ready for thermal sprinkles to encompass metals, ceramics, alloys, plastics, and composites.

Advantages of Thermal Spray Gun

·         Wear Resistance – It can improve overall product quality, reduce maintenance costs and downtime, and help improve energy efficiencies.

·         Performance Enhancement – It can enhance product performance in a number of ways. A copper-based coating can be used to improve electrical conductivity.

·         Extended Life – It can be used to extend the working life of treated parts and components.

Disadvantages of Thermal Spray Gun

·         Disguises the substrate – They are so efficient in many cases, what material the substrate was made of after the coating process, unless stringent records are kept.

·         Cannot precisely evaluate effectiveness – Once it has been applied it is often difficult to tell exactly how well the coating has gone on.

·         Costly set up – It require very expensive apparatus, which can result in a high initial set up cost.

Applications of Thermal Spray Gun

·         Wear Resistant Coatings against abrasion, erosion

·         Corrosion-Resistant Coatings

·         Heat Resistant Coatings

·         Thermal Insulation or Conduction Coatings

·         Electromagnetic Shielding

·         Medical Coatings

Uses of Thermal Spray Gun

Thermal spray coatings are more accepted for electrical purposes. Conductive elements such as copper slag can be applied for conductors. Ceramic elements may be utilized for electrical packing. Conductive metals are more applied to magnetically shield delicate electronics.

Very solid and thick thermal spray deposits have been applied on an innovative basis as cavitations tight materials and in combination with weld overlays as a replacement technique.
