| Need to improve you product finish?
Apply friction, porosity, conductivity or resistance with thermal spraying.
We know how.
Boosting productivity leads to increased demand on surface quality. When passing the limits for what are possible to achieve with surface treatment of solid materials the surface can be improved using coating methods such as the different thermal spraying methods.
Two types of energy are required to spray on a coat: thermal and kinetic. Both of these are generated by gases.
The move towards dense layers has resulted in equipment where the kinetic energy rises in line with reduced thermal input. The evolution of high-velocity thermal spray methods has led to Cold Gas Spraying where the surface material is propelled and plasticized as it hits the substrate, thus combining with the basic material. This procedure is similar to explosion welding.
Spraying is a real money saver and easy to carry out. For an exact surface finish, all you need is a flame, an electric arc/plasma or laser and the right coating material. It improves resistance to wear, corrosion and heat. You can even use this process to increase or decrease friction or change the electrical properties of the surface. Damaged surfaces can be repaired and faulty parts can be redimensioned. In most cases, the surface can easily be post –treated.
To find out more about Thermal Spraying the CD-ROM "Understanding Thermal Spraying" is a good tool.
