HIC Thermal Spray


What is Thermal Spray

  • Thermal spray is a coating process in which melted wire or powder materials are sprayed onto the surface of the work piece.
  • Thermal spray coatings not only repair damaged surfaces, but can replace worn surfaces with a stronger, better-wearing finish that can keep your equipment running better, longer.
  • Thermal spray can also extend the life of your NEW parts by coating them prior to putting them into service – this will maximize your investment in new parts for your process.

Benefits of Thermal Spray

  • Reduced CostInstead of making the entire part out of an expensive material, a high-performance material is sprayed onto a low-cost base material.
  • Low Heat InputThermal-sprayed coatings do not impact the substrates’ microstructure. The coating does not penetrate the base material, i.e., there is no heat-affected zone.
  • VersatilityAlmost any metal can be sprayed.
  • Thickness RangeCan build up from 0.001″ to more than 1″ thickness, depending on the coating sprayed.Coating thicknesses generally range from 0.001″ to 0.100″.
  • Processing SpeedSpray rates range from 3 to 60 lb/h depending on the material and the spray system.

Other benefits include:

  • Thermal Spray is a mature process dating back to the early 1900’s – with proven results
  • Application Specific – Engineered Coating
  • Superior Wear Resistance
  • Excellent Corrosion resistance
  • Dimensional restoration
  • Excellent Bond Strength
  • Provide textured surfaces for traction/grip
  • Heavy Build-ups More Quickly
  • Minimal heat build-up in base metal (<300°F)
