Plasmadize

Thermal spray for extended wear life

Plasmadize® is an enhanced thermal spray composite coating that protects and restores metal parts and has increased lubricity and better mold release than conventional spray methods. An infused matrix of metals, ceramics, polymers and dry lubricants create a structural integrity and non-porous, moisture-proof surface.

Resistance in salt spray testing can range from 300 to 4,000 hours depending on which polymer and substrate is used. The appropriate selection of infused polymer or another surface polymer provides a highly lubricious non-stick surface with a coefficient of friction as low as 0.13 on an 8 RMS surface.

Technical advantages

Plasmadize provides superior properties compared to common coatings such as thermal spray, plasma spray, HVOF, metalizing, twin arc, wire arc and thermal powder deposition. Plasmadize properties include:

  • Operating temperatures from -200°F (129°C) to 1,300°F (704°C)
  • Thicknesses from 0.002 to 0.010 inches
  • Hardnesses beyond the Rc scale
  • Abrasion, corrosion and wear resistance
  • Resilient under bending loads
  • An EWR as low as 0.1 mg per 1,000 cycles
  • A release or gripping surface
  • FDA and USDA compliance
  • Seals surface voids to eliminate porosity
  • Resistance to:
    • Acids
    • Alkalis
    • Most organic solvents
    • Chlorides
    • Sulfites
    • Thiosulfates
    • Pulp bleaching chemicals
