FAQ
Thermal Spray Coating Applications FAQ
What are thermal spray coating applications?
Thermal spray coating applications are industrial uses of sprayed coatings to improve wear resistance, corrosion protection, thermal control, electrical function, dimensional restoration or other engineered surface properties.
How do I choose a coating based on surface performance?
Coating selection starts with the required surface function such as wear resistance, corrosion protection, insulation, thermal barrier, conductivity, low friction or dimensional restoration.
What coating materials are used in thermal spray applications?
Common thermal spray material systems include metal alloys, cermets, carbide coatings, oxide ceramics, MCrAlY coatings and thermal barrier material systems.
Which thermal spray process is suitable for wear resistance?
HVOF and D-Gun are often used for dense carbide or cermet wear-resistant coatings, while plasma or arc spray may be used for other wear or rebuild requirements.
Which coatings are used for corrosion protection?
Arc spray zinc and aluminum coatings, stainless steel coatings, nickel alloys and HVOF corrosion-resistant carbide or alloy coatings can be used depending on environment and part requirements.
