Plasma Sprayed Chromium Oxide (Cr2O3) Insulating Ceramic Coating Service

Plasma Sprayed Chromium Oxide (Cr2O3) Insulating Ceramic Coating Service

Dense Insulating Coatings in Chromium Oxide

We spray high-purity Cr2O3 powder by plasma spraying to build dense, uniform insulating ceramic coatings on stainless steel, carbon steel, aluminium and titanium substrates. The coating raises high-temperature, wear and electrical insulation performance while extending service life and cutting maintenance cost.

Key Properties

  • High electrical insulation - prevents short circuits and leakage in high-voltage equipment
  • Stable above 1000 C with resistance to thermal shock and thermal fatigue
  • Hardness about 1200-1400 HV for outstanding abrasion resistance
  • Excellent chemical stability against acids, alkalis and salts
  • Strong bond strength to the substrate with low spalling risk

Typical Applications

  • Power equipment: high-voltage switchgear, breakers, transformers
  • Electronic components: insulators, capacitors, sensors
  • Industrial furnaces: linings and heating elements
  • Aerospace: engine parts and thermal protection
  • Petrochemical: reactors, piping, valves

Full Service Scope

Equipment assessment, surface preparation, plasma spraying, non-destructive quality inspection and follow-up maintenance support - delivered by an experienced team under strict quality control.
