Welding Alloys: Thermal Spray Wires

Thermal Spray wires are used in arc and flame spray systems. These are austenitic alloys that prodcue dense, well-bonded coatings. These coatings are used for protection against corrosion and high temperature oxidation. They are also used as build-up coatings for dimensional correction.
