Providing a protective coating around different materials and items meant for daily use has become a mandatory norm of contemporary Industries across the world. Whether we are talking about industrial machines, raw materials to be used in construction, or anything else providing engineering coatings is required in every context. A wire flame spray gun is one of the most popular machines used for this purpose. This is a tool that is often used for engineering coating to make the equipment pieces corrosion-resistant. Besides, this form of spraying is also used in the construction industry as well as you can see the products like architectural and structural steels such as fences and gates. These are coated with some stronger coating like coating zinc or aluminum to combat adverse weather conditions.
The Machine
This wire flame spray gun makes use of a wire which is fed into the spray flame of the device. The temperature of this film will be near 10000 k which is enough to melt the wire. The Jet provides an air stream that leads to atomizing the heated particles which are there moved into the substrate. The process of wire flame spraying the atomized form of the heated wire, at the desired surface area, finally provides thermal spray coating. The substance which is applied in this spray coating is the wire frame which has been melted by the flame and it has been atomized by compressed air, which finally leads to the creation of a very fine spray.
Formation of the coating
The formation of the spray has been explained in the previous part of the discussion. When this spray comes in contact with the fixed surface the molten droplets of the spray quickly solidify and create the coating which is formed on the surface of the substrate material which is being sprayed. This process is also referred to as the ‘cold process. In this approach, the air which is used for atomizing can offer much finer droplets that can be used to create softer and finer coatings. In this approach, the rate of flow of the gas which is the oxygen or the fuel can be controlled to produce the range of thermal output needed to meet the requirement of the supply of speed stock. The downstream of the region of combustion, the air jet can also enhance the characterization of the thermal spray.
The advantages
This procedure offers several benefits which can be operational, economic, and technical.
- Technical benefits: Technically speaking these coatings can be easier to apply since they have a lower level of oxide in them.
- Operational benefits: In terms of the operational benefits it can be said that these machines require non-conductive wires which are used for spraying. Further, they create much lower levels of dust while the mechanism is in process. As a result chances of explosions and fire accidents are much lower. These machines are extremely handy, light, and portable and hence can be carried to different site locations for spraying purposes.
- Economic benefits: As compared to using powder using wire for praying coating often works out as more cost-effective. Further, investments for the initial equipment or machine buying are much lower as compared to other procedures. The spray coating deposit offers greater efficiency as compared to other materials like zinc and aluminum.
