Electric wire spraying
Electric wire spraying is a form of thermal spraying widely used for boiler walls of incinerators, repairs of shaft journal or bearing seats or corrosion protection of locks. Such parts are often susceptible to different types of wear. For example, corrosion, erosion or bearing fit wear. The service life of a part can be increased immensely using electrical wire spraying.
The electric wire spraying process
Electric wire spraying is characterised by the two electrically conductive wires transported through the gun. An electric arc is drawn between the ends of the two wires, causing the wires to melt. The melted material is sprayed with compressed air or nitrogen onto the treated surface. A drawing of this process can be seen above.
Advantages of electric wire spraying
The electric wire spraying process allows coatings to be applied quickly and at low energy costs. Essential advantages of electric wire spraying are the large spraying capacity and the excellent adhesion of the coating. But it is also possible to use a combination of different materials in the coatings. This way, we can realise the most optimal coating for your application. Because the equipment for this technique is easy to move, we can also offer this method on site.
Typical coatings for electrical wire spraying
The coating applied during this process may differ, depending on your preferences and environmental conditions. The materials we use for electrical wire spraying are;
- Various steel and stainless-steel alloys
- Molybdenum
- Aluminium bronze
- Tungsten carbide
- Copper and copper alloys
- Aluminium
- Zinc
