Thermal Spray Outperforms Chrome in Many Applications

  • Thick Coating Capability
  • No Part Size Limitation
  • Bonds to a Wider Range of Materials
  • Does NOT Affect Base Metals

Thermal Spray has a
continuous surface.

Chrome Plate has
microcracks that
facilitate corrosion.

Thermal Spray Application is Faster than Chrome
Chrome “grows” slowly on a part and requires numerous process steps versus thermal spray.
